How
the PIC deals with ATC
If the PIC knows and does as the FARs require there will be
little need for ATC to step in and save the situation. MSAW
is a low altitude warning system that exists at many ATC radar
sites. Even so MSAW will work only if properly calibrated
to the latest altitudes. The competent PIC, who is flying as he
should, will never need an MSAW save.
Every PIC on an instrument approach should brief every approach
so as to be familiar with the headings, altitudes and
procedures need to get on the runway. Knowing when and how to
get chart data takes practice. The latest Jeppeson
charts are greatly improved to make getting pertinent information
available. Do not depart until you are prepared.
Read and study the latest changes in the AIM and FARs. Changes
take place every week and most of them will not apply
to your flying. Still, you must read them all to catch those that
do affect you. A PIC makes a point on having all available
information. A PIC will remain current and proficient. A PIC will
confirm every clearance and instruction with a readback
even while performing the instruction.
A PIC will query ATC to confirm any unusual or seemingly inappropriate instruction. Recently, a student and I were given a vector by ATC in error. We acknowledged the vector at the same time ATC was admitting the error so neither of us heard the other. Had we not immediately asked the correct question about the vector and been advised by ATC that the previous vector had been cancelled we would have flown completely away from the published hold.
Pilot
Departure Operations:
The tower airport departure is a multi step procedure. First
you get the ATIS and talk to clearance delivery if radar is involved.
This will involve a transponder squawk, departure route, approach
frequency and a read back. Plan your call-up to ground just as
you would to tower. If you are uncertain or become uncertain don't
hesitate to advise ATC and get assistance as you taxi. ATC can
see the airport much better from the tower than you can from the
ground. On completion of your runup you will contact the local
control (tower).
You have looked in the direction you expect to depart before getting into the aircraft. On getting the ATIS you have planned your runway request for the most efficient departure. If you do not get the most efficient departure runway then you must plan your flight departure to establish the easiest interception of the planned route.
All too few pilots request the 270 departure that crosses them
over the airport on a course that corresponds to the line drawn
on the sectional. Why begin a flight two miles off course if you
don't need to? To help ATC you have named a specific destination
rather than a general direction or departure. This provides safer
traffic avoidance. A good departure call would be:
"Podunk tower Cessna 1234X student pilot ready (runway number)(right
270 on course Xandu)(have any reported traffic)"
ATC is required to 'point out' any known traffic that may affect your arrival or departure. You should acknowledge that you are looking and when seen you are expected to report 'traffic in sight'. Any time you report having reported traffic you make a friend of ATC since you then assume traffic avoidance responsibility. If after thirty seconds or so you have no visual contact be sure to advise ATC.
Tower Departure
Good operational procedures for initial tower call up suggest:
1. Select correct frequency
2. Practice for smoothness, accuracy, and completeness
3. Check for frequency congestion
4. Give full aircraft identification + student pilot
5. Give position and runway (in sequence)
6. Give departure request, direction or destination
With proper radio planning it is easy to go in any direction. A standard departure need not be requested but it is best to include such intent in your call up. Request must be made for straight-out, right/left crosswind, right/left downwind, right/left 270 crossing field 500' above pattern, direct VOR, on course to (destination).
Examples:
"Concord Tower Cessna 6185K ready 32R right standard departure"
"Napa Tower Cessna 6185K ready 18L request straight out"
"Livermore Tower Cessna 6185K ready 25L request right crosswind
departure"
"Oakland Tower Cessna 6185K ready 27R request downwind departure"
"Concord Tower Cessna 6185K ready l9L request left 270 departure
on course Napa"
"Napa Tower Cessna 6185K ready 24 direct to VOR"
While all of the above procedures are correct, I would again suggest a more appropriate call would be to request an 'on course' to you planned destination. This serves as a mini-flight plan on their tape recording and is a more accurate description of your planned route in terms of traffic advisories.
The aircraft is cleared for takeoff. Prior to taking the runway the plane is turned so that both the final and base can be easily viewed from the cockpit. The clearance is just ATC's way of saying go ahead but if anything goes wrong it is your fault. The basic flight rule of VFR flying is, "See and be seen". During the departure, flight checkpoints and any related radio communications should be identified as well as their relationship to your departure from the airport.
Since more and more airports are building parallel runways the pilot should make a practice of making a 10 degree turn away from the adjoining runway to assure no conflict with departing aircraft on the other runway. If in your opinion, traffic conditions permit, and you have some need such as opening a flight plan do not hesitate to request a frequency change even though you may still be within the Class D footprint. The tower may or may not accede to your request.
Pilot
Arrival Operations
If you are a passive pilot who lets ATC make all your arrival
decisions you can just follow orders. This works best if you are
quite familiar with the airport and its procedures. At unfamiliar
fields you need to work out an arrival with ATC. The easiest,
but less efficient way is to request to overfly the field and
let them work you into the pattern. Passive radio operations usually
require multiple transmissions involving questions and answers.
One incompetent pilot with poor radios can tie up the system.
Every light aircraft pilot should be wearing a headset. He should know that microphones are noise canceling. The closer to the mouth the mike the less extraneous noise will intrude. As a pilot you will speak at a measured pace without punctuation. Make no pauses for periods, commas, or thinking. As a student you always let ATC know that you are a student as part of your full aircraft identification so that they can keep an eye on you. ATC communications are practically the same in similar situations. With experience you can recognize the 'canned' aspects and include them in your call-up. The more assertive pilot will take charge of the situation as suggested below. Do all your planning and thinking before you key the mike.
Several planning steps should precede the call-up to a tower-controlled airport. You should get the ATIS well away from the airport. This means you will know the direction of the preferred runway. You will know if a substantial crosswind is involved. You will listen and orient other traffic with reference to your arrival. You will plan your arrival so as to make your initial call-up at a selected reference point and altitude. Reference points are best when they are specific identifiable spot locations. Altitudes below 3000 feet AGL are safest when not at even thousands or five hundreds.
As a student you would be well advised to write your expected
arrival out without any shortcuts. Have it so you can read it
off. After doing this a few times the writing will no longer be
required. Where multiple runways exist some variations are to
be expected. With the planning taken care of, you take a deep
breath and practice getting everything out in one smoothly paced
flow. While you are practicing you will be listening to the radio
for ATC references to both inbound and outbound traffic.
Ready begin:
"Podunk tower (Cessna 1234X)(reference point)(at altitude)(with
ATIS)(arrival path)(will report)
(looking for traffic)".
You win if the tower says, "34X approved as requested."
Properly presented and arranged radio work by the pilot helps the controller sort out the factors of aircraft type, position altitude, intentions, and expected report. Making it easy for ATC lets them make it easy for you.
Tower
Arrival
Towers are now acquiring BRITE monitors that give the controllers
a radar screen picture of their area. The pilot has no way of
knowing if this exists without a tower visit. There are different
types of BRITE with differing capabilities. By letters of agreement
(LOA) the tower may have been given, by the terminal facility,
a very specific area and transponder codes for use in that area.
BRITE (A radar screen) is used to determine position, provide
advisories, suggest headings, (not a vector) and to provide information.
The fact that radar is becoming increasingly available makes many
arrivals more controlled and seemingly easier. Do not rely on
a radar environment to protect you from other aircraft. Just be
aware that proper radio procedures are expected in the radar environment.
Also, should a suggested vector, heading, or heading fail to avoid
traffic or weather you as a VFR pilot bear the primary responsibility.
Under the present FARs anything bad that happens under VFR is
not necessarily the fault of ATC.
Always get the ATIS; communicate from a known (pre-planned) checkpoint 10 to 20 miles out. If you are unfamiliar, so advise ATC. If another aircraft is arriving so as to conflict relative to your position don't hesitate to give a progressive call as to your position and altitude. Awareness of the relationship between aircraft, their reporting points and your position/route is an important element in flying safety. For this reason report and confess if you are in an unfamiliar situation. ATC and other pilots can then be made aware of a potential surprise. Much better aware and watching than SURPRISED.
Standard terms for 'straight in' arrivals:
"34X 3-4 mile final" May include such terms as "approaching,
passed VOR 20 seconds ago, etc. with altitude.
"34X two mile final" This is a required call and if
not given by ATC as part of your clearance, give it anyway.
"34X Quarter mile final, low for 32 right"
"34X short final, high for 32 left"
Standard terms for "base' arrivals:
"34X two mile base" Again, this is a required call
if not given by ATC in your clearance, give it anyway.
"34X one mile base, high"
"34X close in base"
"34X wide base"
Standard terms for downwind arrivals:
(A left downwind to a left runway or a right downwind to a right
runway never need be requested just say that you will report.)
"34X right downwind, high"
"34X wide left downwind"
"34X extended downwind, call my base"
"34X Abeam numbers, request short approach"
Before and after your initial clearance the tower may communicate with another aircraft. Always listen and mentally calculate position/altitude information that may affect your safety. The tower may issue to you a traffic advisory and may ask your position. It is wise to keep a running reference as to your location referenced to known checkpoints. i.e.
"34X Willow Pass thirty seconds ago two thousand looking
for traffic"
"34X coming up on the BART yards at one-thousand five hundred
have traffic"
If the tower fails to give you an advisory, go ahead and give your own advisory as above for the other pilot's benefit.
Standard terms for 'straight in' arrivals:
"34X 3-4 mile final". May include such terms as
"approaching, passed VOR 20 seconds ago, etc. with altitude.
"34X two mile final". This is normally a required call
and if not given by ATC as part of your clearance, give it anyway.
"34X Quarter mile final, low for 32 right".
"34X short final, high for 32 left".
Standard terms for "base' arrivals:
"34X two mile base". Again, this is a required call
if not given by ATC in your clearance, give it anyway.
"34X one mile base, high".
"34X close in base".
"34X wide base".
Standard terms for downwind arrivals:
"34X right downwind, high".
"34X wide left downwind".
"34X extended downwind, call my base".
"34X Abeam numbers, request short approach".
As with Ground, acknowledge any tower clearance or instruction
with the word HOLD in it since it confirms your understanding
that at some point you are to STOP.
Tower: 34X taxi closer and hold short 19L...
Response: 34X understand closer and hold short
Tower: 34X taxi into position and hold...
Response: 34X position and hold
Acknowledge any traffic information
Tower: 34X # 2 behind Cessna on base...
Response: 34X looking
When you see traffic...
34X have traffic
When you don't see traffic...
34X negative traffic
The only clearance that need not be acknowledged is for take off, however, it is not wrong to acknowledge it if it can be done without causing delay in moving the aircraft.
--If the controller is obviously busy don't bother with making
requests...do that later. If the controller does not give you
time to acknowledge...don't.
--If you are given a command - EXECUTE and then use the radio
--If at any point you do not understand use "34X say again"
or "34X say again everything after..."
Class
D ATC Provides No Traffic Separation
ATC is required to provide aircraft separation only for the
length and width of the runways for arriving and departing aircraft.
Category I aircraft must have 3000 feet separation on the runway.
The landing clearance is issued in anticipation that the required
distance will exist on arrival. As ground control, ATC is required
to provide separation only sufficient to prevent accidents. At
night only one aircraft is allowed on the runway at a time. A
departing aircraft is allowed to be over the runway at the prescribed
distance. The entire airspace of Class Delta is the responsibility
of the see and be seen pilot. Even though communication is required
the responsibility of ATC does not include separation.
The rule(s) for intersecting runways require that only one runway will own the intersection at time. This means one aircraft owns the runway up to the intersection at a time. Once past the intersection its 'ownership' can pass to the other runway. The LAHSO can selectively limit the use of an intersection.
The few additional circumstances where ATC is required to provide separation or at least a notice of separation is for wake turbulence, restricted altitudes for opposite direction traffic and IFR separation for the entire Class Delta Airspace when below VFR minimums. Only one IFR aircraft is allowed into the Class Delta Airspace, when that airspace is below VFR minimums, at a time unless the controller can see and accept separation responsibility OR one of the pilots have a visual of the other and agrees to maintain visual separation. I have flown into the latter situation several times. I am above the airport and have visual with a departing IFR aircraft. I have been cleared into the airspace and to land as long as I have visual with the departing aircraft. It works.
Entering Class
D airspace
Suggestions by an ATC tower to answer questions and reduce
problems. Two-way communications must be established prior to
entry and must be maintained in Class D airspace. Pilots should
contact the tower with position, altitude, destination, and any
requests.
1. Listen before you transmit. Know what you want to say before
you key up.
2. Acknowledge instruction.
3. Advise tower as soon as possible if you request pattern work.
4. Request preferred runway on initial call. It's not guaranteed,
but they try.
5. Readback runway assignments. This is now a national requirement,
not just "roger" or two clicks of the mike button.
6. Readback runway hold short instructions. ATC is required to
obtain from the pilot a readback of all runway hold short instructions.
7. When ready for departure, say runway and departure request.
This saves you and ATC extra transmissions that add up when it's
busy.
Crossing Class
D Airspace
"Napa tower Cessna 1234X Crockett at l900 request flight
through your Class D airspace surface area enroute Santa Rosa
will report clear"
Tower will normally approve the transit, give you the current
altimeter setting and remind you to report clear.
Radar
Communication
The callup to every radar facility is the same.
Initial Call
Travis approach, Bay departure, Oakland Center
Name of facility, full aircraft identification + "Student
pilot " over
Travis Approach Cessna 6185K student pilot over
The reasons for this brevity is because the radar controller
has a multiplicity of tasks. In addition to your frequency he
may have a military one. He has a phone line for contact with
controllers of adjacent areas. He often records data and writes
notes. In low traffic periods one controller may have two areas
and two frequencies. Under certain workload/weather conditions
VFR advisories may not be possible. When this condition exists
you will be so advised. A visit to a radar facility will help
you be more understanding as to why the controller does not answer
immediately.
A more distant initial callup procedure allows the controller
to select when to contact you as his workload permits. Wait at
least 30 seconds before calling again. The more efficiently you
communicate the more likely it is that you will be accommodated
since good communications reduce the workload.
Your first flight into complex airspace can be made much easier
by planning the flight precisely for the radio procedures you
can expect. This means that you want to have a frequency list
with variables. During certain days and times ATC facilities combine
frequencies because of reduced traffic. It is usually difficult
to tell just when this occurs so it is important that you familiarize
your self with the possibilities. A phone call to the facility
is a good starting point.
A visit is even better.
Your initial callup consists of whom you are talking to, who you are and "Over". Do not try to squeeze all the Class Delta information into an initial radar callup. The radar specialist has a far more complex communication system than the 'Local' tower controller does. Let the specialist get back to you when he/she is ready. This factor means that you must make your initial call well away from the need for a clearance or transponder code. Allow yourself time according to aircraft speed.
When the specialist gets back to you, it is time for you to have prepared all the necessary information. Aircraft type and /code, location, altitude, destination w/ATIS, and any special intentions or requests. Always write down the transponder code assigned, read it back and then on 'standby' put it into the transponder. Acknowledge any heading/altitude assignments and comply as sequenced. If you are uncertain on any item of a clearance have that part of the sequence repeated by saying, "Say again ".
ATC Radar Acknowledgment:
Make NO response if told to standby. When the controller is
able you will be told to go ahead. However, you may be occasionally
'forgotten".
"Cessna 85K go ahead with your request"
When the controller acknowledges your existence give the particulars
of your flight and aircraft.
Full call sign
Type of aircraft
Present position, present altitude and final altitude.
(Altitude given is checked with radar encoder readout)
Destination
En route altitude
Request
You give all the data but ADD aircraft type present altitude and
final altitude. The controller will ask for anything you leave
out. The ATC specialist adds the type information to the radar
data block. The present altitude information is used to check
the accuracy of your transponder encoder. Once you are established
at an altitude do NOT leave that altitude without first advising
ATC. Your transponder code assignment will indicate IFR/VFR and
destination.
The response would be similar to:
Cessna 150 6185K Student Pilot two north Concord VOR out of
two thousand two hundred for five thousand five hundred enroute
Chico (The enroute altitude is determined by magnetic course.)
ATC will assign a squawk and confirm your Mode C operation by
saying,
"85K squawk 5234", say altitude.
The importance of correct, concise, and accurate communications
when dealing with a radar facility is essential. You are required
to fly assigned headings and altitudes. If you wish to change
heading or altitude advise ATC. If there is a traffic conflict
ATC may provide an alternative. Always write down squawk and frequencies.
Always repeat back squawk, frequencies, heading, and directions
as much as practical. If you need something repeated, say so.
If you cannot visually locate conflicting traffic, do not hesitate
to indicate that you will accept (want) a vector for traffic avoidance.
When given a handoff to another sector you just have to tell the
controller your altitude.
"Sacramento Approach Cessna 6185K level at 6,500"
Again, if no response, wait 30 seconds and call up again. When
work load permits they will respond. There is a more complete
radar study included with Cross-Country Procedures.
Do not believe that being on radar relieves you from 'see and
avoid' responsibility. As a VFR flight you are relatively low
on the ATC totem pole. When ATC radar advises you of nearby traffic
you should acknowledge the 'point out with.
"85K have traffic"
Do this only if you are sure of the traffic direction, distance
and aircraft type. If you are uncertain or have failed to see
any aircraft of the type indicated you say,
"85K negative traffic"
If after thirty seconds to a minute you still have not identified
the traffic and you feel that a hazard may be involved, you should
request vectors for avoidance by saying,
"85K will accept vectors"
The controller may indicate that traffic is no longer a factor
or may give your a vector by saying,
"85k turn to 030"
Your response will be the direction of the turn and the heading
given so as to establish the certainty of your instructions.
"85k left/right to 030"
When you are clear of the traffic ATC will instruct you to resume
your own navigation.
If your transponder is not making a reply or is giving the wrong
code ATC will request that you recycle. This means to turn it
off then on and roll through the numbers again. This often is
sufficient to fix the problem. If some aspect of transponder operation
is unsatisfactory ATC can usually work with a primary signal.
Under the escape clause "unless otherwise authorized or directed
by ATC" you can be given a waiver. The willingness to ask
for help when you need it from ATC is more important than whether
your transponder is working. Not only can ATC give you vectors
they can give you 'no gyro' aid that will get you out of IFR conditions
into VFR.
Squawk is assigned according to the National Beacon Code Allocation Plan. Centers are assigned different for different flight operations. There is a series for selected departures, another series for flights within a Center's airspace; and a different series for departures that will cross center boundaries. Squawks can be copied only by Centers far apart.
A given ATC facility will be given code sequence for different uses such as VFR, IFR or tower en-route. Within a given operation, they assign them in sequential order and then start over again. No two aircraft can fly with the same code inside the airspace of a specific facility. Pilots are occasionally asked to change their code if you are traveling a long distance. Certain codes are used to show your destination to each facility as you pass through.
FSS Procedures
The FSS may have up to 12 radios operating from one switch panel.
It is necessary for the pilot to know the differing dedicated
frequencies and how to obtain them. The emergency 121.5 and FSS
universal 122.2 frequencies do not usually appear on charts or
other sources. You, the pilot, are expected to know that these
are common to Flight Service Stations. If a frequency for an FSS
is followed by an R, it means that the FSS can only receive; if
a frequency is followed by a T, it means that the FSS can only
transmit on that frequency. Since some of the frequencies may
be far beyond the line of sight requirement it is important to
be careful in making your frequency selection.
Failure to mention the frequency you are listening on may require
an additional callup. You always save time in communications by
doing it right the first time. Your initial communication should
include the words, ....listening on (Frequency). You can improve
your FSS communications comfort level by making PIREPS when making
local flights. The FSS can offer complete weather service, frequencies,
airport information, navigational assistance and emergency assistance.
Except for the callup, other communications can be conversational.
Some FSS operations are now only part-time. Do not try to stretch
radio range. Use nearest available frequency. Know how to select
the appropriate FSS frequency, how to use it correctly and when
to use it. Some FSS operation are only part-time. The FAA is in
the process of making most FSS operations via remote facilities.
Oakland and Rancho will service most of Northern California as
the smaller stations are phased out. Reference the AIM Chapter
4-92, 5-81, 70-50/58.
An FSS briefer must master six different phases of operations.
1. Preflight
2. Standard briefing, abbreviated briefings, outlook briefings
3. Weather observation
4. Flight data
...............The getting flight plans, messages, search and
rescue,
5. Inflight
................All air to ground communications, inflight flight
plans, position reports, weather requests, lake and mountain service,
................flight watch and airport advisory service (AAS)
6. Airport advisories
FSS
Problems
Key question: "If you were a pilot would you go?
--Pilots who do not understand terminology
--Pilots who cannot listen and ask questions related to information
already given.
--Pilots who take offense at required "VFR not recommended"
when weather is below a specific point.
--Pilots who cut the briefing short. Allowed but presents problems
for briefer who is required to follow a specific format.
--Pilots who call flight watch for the wrong reason such as giving
a position report.
FSS Communications
The callup to an FSS uses the format.
"Name of FSS radio, aircraft identification listening on
(frequency)"
Listen for frequency congestion and check frequency. The initial
FSS contact is always the same....
34X Callup: "Oakland Radio Cessna 1234X listening 122.5.
Since the operator may be on any one of a number of radios at
a different frequency you must wait before trying again.
FSS: "Cessna 1234X Oakland Radio go ahead"
Flight
Watch
Sitting very near the FSS radio specialists is the Flight
Watch radio specialist. His duties extend from 6 a.m. to 10 p.m.
local times. This is a nationwide weather information service
operating on 122.0. The first Flight Watch station was activated
at Oakland about twenty years ago. Since this is the only frequency
he may have up to eight remote locations. Oakland has one at Reno,
Red Bluff, Oakland, Big Sur, Sacramento, Fresno, and Ferndale
near Eureka. There are three HiWAS frequencies for the airlines.
Any aircraft over 5000' should be able to contact Flight Watch.
The essential is that the pilot give the name of the nearest VOR.
Response may not be immediate because the specialist may be 'working'
another aircraft hundreds of miles away from your location. This
is an excellent frequency to monitor when flying cross-country
but contact should be related to weather. You may be able to give
another pilot valuable information about your route as well getting
real time information for your destination.
34X: "Oakland Flight Watch Cessna 1234X (NEAREST VOR) over"
Always include in initial call up your location related to the
nearest V0R. This allows the operator to select the best remote
transceiver for your location. This is a weather service and,
except in emergencies, should be limited to weather. Requests
and information have a regular format but conversational exchanges
are acceptable.
EFAWS: "Cessna 1234X Oakland Flight Watch go ahead."
34X: "Cessna 34X VFR CCR-RNO have hit stronger than forecast
head winds near Blue Canyon. Estimate winds to be 340 at 18-kts
at 9500. Light turbulence high cirrus 40-mile visibility. Do you
have additional information also current surface winds at Reno?
Uncontrolled Airport
Regulatory provisions relating to traffic patterns are found in
Parts 91, 93 and 97 of the FARs. ACs 90-42 and 90-66A are advisory
for safety and efficiency. See-and-avoid requirement fully applies.
All available information from AFD (Airport/Facilities Directory)
AIM and NOTAMs is required by FAR. Use of Visual indicators (segmented
circle, windsock) must be used. Statistically a midair is most
likely to occur in the pattern of an uncontrolled airport.
The one place you can reduce the cost of being wrong on the radio
at uncontrolled airports by always assuming the worst possible
situation at an uncontrolled airport. Make it a point to report
your positions and intentions several times on an IFR uncontrolled
airport arrival. Even an IFR approach that makes a straight-in
to an uncontrolled airport may increase the safety factor by doing
a circle with a standard pattern entry.
The straight-in approach to an uncontrolled airport is not, of
itself, inherently dangerous. Straight in approaches, while not
prohibited, must not be disruptive to normal pattern operations.
Possible straight in approaches (as with instrument approaches)
greatly increase see-and-be seen requirements. The straight-in
eliminates the need to overfly and make a 45 entry. AC 90-66A
advocates the 45 entry but indicates that the straight in, IFR
or VFR, should not require maneuvers that disrupt other traffic.
FAR ,91.127(b) Says that all turns shall be to the left unless
otherwise depicted. A straight-in requires no turns. NTSB Administrative
Law Judges have found the straight-in a violation of FAR 91.113.
Two
different kinds of Unicom.
1.) Every tower airport has a unicom on frequency 122.95. The
callup gives, "Airport name unicom, aircraft identification
and request".
Due to the personnel or physical constraints several calls may
be required to establish contact. Commonly used to order fuel,
services, or transportation. 122.95 is the universal nationwide
unicom frequency for TOWER fields. Such an airport unicom is used
for ordering fuel, taxis, making phone calls or personal requests.
It is frequently advantageous to contact the unicom a few miles
out so that transportation will be there when you land. Some fields
may have additional frequencies but 122.95 is standard. Only at
the very largest airports will this frequency operate on a 24-hour
basis.
2.) Many uncontrolled airports may offer unicom service on the
CTAF frequency given on the sectional. This means that there may
be someone on the field to respond to a radio call during normal
working hours.
The callup is:
"Name of field unicom, aircraft identification, location,
altitude, request traffic advisories( or other request)and name
of the field."
If there is a unicom response it may be limited to suggesting
a runway and traffic direction. (The Good Samaritan situation
has created liability they may not wish to assume with additional
advice) If there is not unicom response all further transmissions
should be addressed to "traffic".
Non-radio-equipped aircraft are expected to determine pattern
in use. Since one in five General Aviation aircraft do not have
radios. Radio use is not required but good sense dictates monitoring
and use. One of the problems at uncontrolled airports is radio
complacency. You begin to believe that if no one is on the radio
that no one is there. Don't you believe it.
Some of the CTAF frequencies are quite congested on weekends.
It is important that the NAME of the place/airport be the first
and last word of any CTAF communication. This alerts pilots in
your area and allows others to discount your presence. This change
is of relatively recent origin, about 10 years. You will still
hear many pilots failing to use this procedure because they were
not initially taught that way. Relearning is, perhaps, the most
difficult aspect of flying. Relearning is also one of the most
resisted phases of instruction. However, what was good enough
forty years ago or even five years ago is not good enough today.
Always include the runway number you plan to use. This provides
an additional alert if someone missed the place/airport name as
well as possible winds/ runways at nearby airports. Do not totally
rely on such runway calls for what you should use. Since the use
of the CTAF frequency nor the 45-degree entry is not REQUIRED
you must use see-and-be-seen vigilance in all directions. If you
have reason to believe density altitude over 1000' above AGL exists
it would be helpful to include your computation in your communications
with other aircraft.
The eyes and ears of the ATC controller augment situational awareness
at a tower-controlled airport. At the uncontrolled airport it
is only the pilot(s) who are responsible. The see and be seen
limits of situational awareness must be supplemented with what
you hear and orient over the radio. The radio, properly used,
tells everyone else where to look. Other pilots must use what
you say on the radio to both locate and anticipate your actions.
There is a vital supplement to visual contact in the radio communications.
The radio is the only way you can express intent and allow any
other pilot to anticipate what you are going to do. Situational
awareness relies on the pilots both speaking, listening, responding
and looking
Total awareness requires both the eyes and ears. You tell other
aircraft where you are, your altitude, and your intentions. This
can be give in specific words or by implication. "34X right
downwind for 25" tells other pilots that you are at pattern
altitude, flying to the left side and parallel to runway 25 and
will soon be turning base. Other pilots may (should) be listening
and interpreting your call to their situation. An aircraft with
pertinent information or in the immediate vicinity may well respond.
Communication only occurs when there is both a speaker and a listener.
This self-announcing process of giving position, altitude and
intentions is the only way to can fill in the situational awareness
of other pilots. If you fail to begin and end each announcement
with the airport name you just confuse the situation for all concerned
on the frequency. "What airport?, is a common call when airport
identification is left out.
Unicom frequencies now in use (1997) are 122.7, 122.725, 122.8,
122.975, 123.0, 123.05, 123.075
122.75 is air-to-air and private airport operations
122.9 is multicom at unattended and uncontrolled airports
122.925 is an environmental protection frequency.
122.85 air search and rescue

DON'T MISREAD WIND SOCK, TETRAHEDRON, OR SEGMENTED CIRCLE!!!!
Misreading is easy to do.
Depart over the field on a reciprocal 45-degree to the 45-degree
entry. Lose half of altitude to pattern altitude. Execute a left/right
course reversal while descending to pattern altitude on 45-degree
entry. You should be at pattern altitude before reaching the pattern.
This greatly improves your see/be seen opportunities. Arriving
slightly high is better with high-wing and slightly low with low-wing
aircraft for better visibility. Watch the ground for shadows.
Look for additional ways to determine runway in use, such as arriving
or departing aircraft, smoke/dust/waves. Nearby airports are good
indicators. Try to plan the most efficient arrival conducive to
safety. Avoid the pattern altitude until you are in it.
DON'T FLY INTO THE PATTERN ALTITUDE IN THE BLIND!!!!!

PRIORITIES:
1. Fly the plane
2. Maintain proper altitudes and headings
3. Keep eyes outside cockpit and watch for traffic
4. Communicate
122.9 Traffic only advisories at airports without frequency on
sectional
123.6 Uncontrolled field with FSS for arrival and departure only
Common
mistakes:
1. Not calling up soon enough to get advisory
2. Not observing traffic pattern/windsock direction
3. Turning downwind too close to runway
4. Becoming distracted and not attending to airspeed and pattern
orientation
5 Trying to hit the end of the runway
6. Delaying addition of power if low
7. Delaying go around if a poor approach/flare
8. Not clearing runway immediately
DEPARTURE:
1. Full 360 degree clearing turn on ground prior departure
2. Advise traffic of departure and direction
The addition of the name of the airport at the end of each radio
call is by an AD (Advisory Circular) June of 1985. When an omission
occurs you can be certain that the pilot has avoided additional
training since 1985.
Non-unicom Uncontrolled Airports:
All callups are made to the airport "Location name, traffic,
aircraft identification, position, altitude, intentions and location
name" on 122.9. Any responses to your "blind" communications
would be from other aircraft.
Aircraft to
Aircraft:
All callups must, according to FCC, include full identification
of both aircraft. 122.75 is the aircraft to aircraft frequency.
It is best to use this frequency by prior arrangement with another
plane.
Most airports have several special situations which require special
flight procedures. The best way to get this information is by
visiting the tower. Make a phone call to the airport and have
a list of prepared questions. I would suggest arranging a discussion
and analysis for any arrival and departure at neighboring airports
with a pilot familiar with the location. In my instructional area
there are airports in differing quadrants that vary from having
an ARSA underlying a TCA to uncontrolled.
Lost Communications
Being unable to communicate to ATC is not a VFR emergency.
There are standard arrival procedures to use and ways to let ATC
know that you have a problem. The most common causes of lost communications
are pilot error in use of his equipment. Low time pilots are most
apt to experience lost communications. Under high workload situations
a pilot is likely to not to catch a lost communications problem.
Lost communications are usually discovered when trying to communicate.
Experience has indicated the following order of difficulty. The
average time before problem recognition is nearly ten minutes.
--Misuse of audio panel causes over 50% of problems
--Using wrong radio
--Volume too low
--Incorrect frequency (Failure of pilot to write down frequency.)
--Forgot to change frequency
--Using wrong frequency usually from failure to write down frequency.
--Two simultaneous transmissions resulting in frequency whistle
--Stuck microphone switch (Causes 60% of blocked frequencies.)
--Electrical failure
--Given incorrect frequency by ATC
--ATC radio problem
--Asleep (64% of radio incidents occur in cruise flight.)
The use of a radio log sheet which is completed prior to each
flight is a good practice. When you have only one radio you have
a limited capability and a self-limiting problem. Always keep
the audio panel on speaker or phone. Monitor a frequency until
you are ready to communicate.
When using multiple radios, develop a technique of always making
your initial contact on the #2 radio and rolling that frequency
to the #1 as soon as contact has been established. If you have
dual flip-flops keep your communications in the #1 and ATIS frequencies
in the #2. This removes the audio panel as a problem. Develop
a sequence of movements for changing a frequency that will include
the setting of the next expected frequency. The next frequency
will often be given to a preceding aircraft, listen up and put
it into your radio. This will unload one facet of the next ATC
directive requiring multiple actions. Take all the help you can
get.
When radios get fancy some basic skills fall. Under single radio
operations you kept a written radio frequency log. With flip-flops
you may tend to neglect your log. No problem until your frequency
display LED fades out or loses a leg or two. Now you get to practice
locating a missing frequency by bird-dogging through other ATC
facilities. Towers can give your many of the radar frequencies
in their area.
Talking a flight
1. Study area maps and become familiar with all checkpoints.
2. Select call-up checkpoints and altitude for both directions.
3. Plan most economical departure/arrival traffic permitting.
4. Make a frequency list for both directions.
5. Before you get into the plane point the way you want to go.
6. Verbalize what you will say to the tower from all departure
runways.
7. Say 'STUDENT PILOT' when using full identification.
8. If radios do not appear to work, suspect yourself first.
9. Acknowledge all communications except, "Clear for takeoff".
10. Face approaching traffic while holding short.
11. Clear (turn toward base & final) the runway before takeoff.
12. Refuse "Cleared for immediate" as a student pilot.
13. Know your Class D airspace footprint line for frequency change.
14. Start listening to arrival ATIS as far away as possible.
15. Listen to other planes as they arrive/depart so as to be situational
aware of traffic hazards.
16. Verbalize what you will say to the tower for all arrival runways
with requested approach and reporting point.
17. Initiate descent to allow smooth entry into pattern.
18. Have the pattern altitude MSL written down on sectional.
19. Communicate well outside the tower controlled airspace.
20. If you start getting behind, so to slow flight.
21. Keep track of inbound/outbound checkpoints so that at any
time you can give the tower your position and altitude.
22. If traffic conflicts seem possible give position and altitude
without being asked.
23. If in doubt request to overfly above pattern altitude for
orientation.
24. If you become confused--communicate.
25. Acknowledge all traffic calls (looking-have-negative)
26. Advise ATC early if having any kind of difficulty.
27. Obey an ATC command and then acknowledge.
28. Fly with the microphone in your right hand
29. Get a good headset and mike switch as soon as possible.
30. In the pattern, verbalize your clearing and actions in flying
to keep normal approach.
31. Respond to the tower only if control of plane is assured.
32. Go to slow flight if you are #3 or more in the pattern.
33. Accept short approach only if certain of your capability.
34. Do not force clearing the runway; be smooth and gentle.
35. Put microphone in left hand while on the ground.
36. Taxi well clear of runway for following traffic.
37. Cross the hold bars before changing frequency.
38. Face possible approaching traffic if crossing a runway.
39. Request taxi assistance if you are the least uncertain as
to how to proceed.
Declaring an
Emergency
There are no requirements for the declaration of an emergency.
If you are having difficulty and have doubts as to your ability
to guarantee a safe outcome, declare an emergency. Use Pan Pan
if there is no immediate danger, if you have any doubts as to
the urgency use Mayday. You are more likely to be facing FAA paperwork
for not declaring an emergency than you are for declaring one.
Take the easiest/safest way out. Contact ATC and get all the help you can. You can expect an FAA interview concerning your judgment/decision to declare an emergency. FAA will not second-guess what happened in the cockpit. If the pilot is reasonable in saving life and property an FAR deviation will usually be considered justified.
ATC, "Say intentions".
Pilot, "Say suggestions."
