Communications, Light Signals, and Runway Lighting Systems

The area note is short and consequential: the evaluator must select at least one Task from this Area of Operation. With only two Tasks — Communications/Light Signals and Traffic Patterns — nothing in the note stops the evaluator from selecting both, so prepare both to teaching depth.

Read the ACS verbs, because they set the standard for every card that follows:

• Knowledge — "the applicant demonstrates instructional knowledge by describing and explaining"
• Risk — "the applicant explains and teaches how to identify and manage risk"
• Skills — "the applicant demonstrates and simultaneously explains how to"

That last one is the trap. Flying a clean radio call silently is a fail. You have to fly it and narrate it, the way you would with a student in the right seat (AI.VI.A.S1–S4).

Teach it as workload management, not as chart trivia. AIH ch. 1 is explicit: reviewing the appropriate chart and setting radio frequencies well in advance of need reduces workload as the flight nears the airport, and checklists should be performed well in advance so there is time to focus on traffic and ATC instructions.

The ground lesson:

• Chart Supplement — the complete listing for the airport.
• Sectional and airport diagram — tower/CTAF boxes and the automated weather frequency.
• NOTAMs — frequency and tower-hours changes.
• Have the learner listen to ATIS, ASOS, or AWOS and then monitor tower or CTAF early, to build a picture of the traffic before arriving (AIH ch. 1).

Then make it a rule in your syllabus: frequencies loaded in the standby side before the descent begins. A student hunting a frequency at pattern altitude is a student not looking outside.

Fix the airplane first, then the workload, then the radio — never the radio call itself.

AIH ch. 2 names the behavior: responses to anxiety range from a hesitancy to act to the impulse to do something even if it is wrong, and many learners freeze and are incapable of doing anything to correct the situation causing the anxiety. That is a known reaction, not a character flaw.

In sequence:

1. Confirm who is flying. If the freeze has cost airspeed, altitude, or spacing, take the controls with the words "I have the flight controls" (AIH ch. 9).
2. Offload the radio. Make the call yourself. AIH ch. 1 lists delegating a radio frequency or chart task to another pilot as a legitimate workload-reduction option, and you are that other pilot.
3. Restore the priority. The instructional line is the same one AIH uses for an overloaded learner: stop, think, slow down, and prioritize.

Say nothing critical in the pattern. The debrief is where the learning happens.

The technique is to treat fears as a normal reaction rather than ignore them — countering anxiety by reinforcing the learner's enjoyment of flying and teaching them to cope with their fears (AIH ch. 2).

So:

• Name it as normal. "Everyone jams up on the radio. It is the most public thing you do in an airplane."
• Do not build the lesson on consequences. AIH warns against continuously citing the unhappy consequences of faulty performance; present good practice as conducive to satisfying, efficient, uninterrupted operations.
• Remove the uncertainty. Anxiety attaches to specific operations, and instructors should introduce those operations with care so learners know what to expect and what their reactions should be (AIH ch. 2). For the radio that means scripting the exact calls before the flight.
• Give a floor. Agree that any time it goes sideways, the student says the airplane's call sign and "say again" — never silence.

Watch for the difference AIH draws between normal reactions, which signal a need for special instruction, and abnormal reactions, which may signify a deep-seated problem.

Phraseology failures are communication failures, and AIH ch. 4 names four barriers you are fighting: lack of common experience, confusion between the symbol and the symbolized object, overuse of abstractions, and external factors.

Two apply immediately:

• Lack of common experience is "probably the greatest single barrier to effective communication." Your student has never heard the tape you have. Words are only stimuli — they do not carry meaning by themselves. So do not explain a call, play one, and fly the pattern on the ground first.
• Overuse of abstractions. "Make the call" is abstract. "Say: Riverside Tower, Warrior Three Alpha Bravo, midfield left downwind, runway nine, full stop" is concrete.

Teach the AIM/Pilot-Controller Glossary phrasing (AI.VI.A.S2) and the ICAO phonetic alphabet for identifying the aircraft (PHAK ch. 14, Figure 14-41). Remember primacy — what is learned first creates an almost unshakable impression, so teach the call correctly the first time rather than letting a sloppy version set (AIH ch. 3, The Learning Process).

(PHAK ch. 14, Figure 14-42.)

Acknowledgment: rock the wings in daylight, blink the landing light at night. Cite that one carefully — the sentence in PHAK ch. 14 attaches it to acknowledging ATC transmissions when the transmitter is inoperative, not to light signals as such. The technique is the same either way; the source is not, so answer with the procedure and let the evaluator supply the paragraph.

Teaching note: the column a student memorizes is almost always "in flight," and the one they get asked about on their own checkride is "on the ground." Drill the ground column separately.

Teach it as three separate failures, because the procedure differs (PHAK ch. 14):

• Receiver inoperative — remain outside or above Class D until the direction and flow of traffic is determined. Advise the tower of aircraft type, position, altitude, and intention to land. Continue, enter the pattern, report position as appropriate, and watch for light signals from the tower.
• Transmitter inoperative — follow the same procedures and also monitor the appropriate ATC frequency, acknowledging transmissions by rocking the wings in daylight and blinking the landing light at night.
• Both inoperative — remain outside Class D until the flow of traffic has been determined, then enter the pattern and watch for light signals.

Two judgment items your student needs more than the procedure: radio malfunctions should be repaired before further flight, and NORDO arrivals are not accepted at busy airports — so if radio comm is lost, landing at a nontowered airport with lower traffic volume is often the better decision (PHAK ch. 14).

Note the regulatory backstop for a tower in Class G: if the aircraft radio fails in flight, the PIC may operate and land if weather is at or above basic VFR minimums, visual contact with the tower is maintained, and a clearance to land is received (91.126(d)).

Most in-flight radio failures are a switch, not a box. Teach a fixed troubleshooting order so a nervous student has something to do:

1. Volume and squelch — a squelched receiver is silent, not failed.
2. Audio panel — wrong transmitter selected, or speaker/phone selection.
3. Headset and jacks — the cheapest and most common failure; try the hand mic.
4. Stuck mic — if the frequency has gone completely quiet, suspect your own push-to-talk and switch transmitters.
5. Active versus standby frequency, and a mis-set digit.
6. The electrical system — a comm failure accompanied by other electrical symptoms is an alternator or bus problem, not a radio problem.

Then teach the habit that saves the flight: transmit blind anyway, because only the receiver may have failed. And build the habit of positively identifying a control before actuating it — AFH ch. 9 makes that point about the gear and flap controls, and the same discipline belongs on the avionics stack.

Start with what the box is: the transponder is the airborne portion of the secondary surveillance radar system, and ATCRBS cannot display secondary information unless the aircraft is equipped with one. A code is four numbers from 0 to 7 — 4,096 possible codes (PHAK ch. 14).

Standard phraseology your student should recognize (PHAK ch. 14, Figure 14-43):

• "Squawk (number)" — operate the transponder on the designated code in Mode A/3.
• "Ident" — engage the IDENT feature. Teach that ident is pressed once, when asked — students hold it or press it unprompted.
• "Squawk Mayday" — operate the transponder in the emergency position, Mode A Code 7700 for a civil transponder.

If a situation becomes threatening, transmit on the emergency frequency 121.5 MHz and set the transponder to 7700 — most facilities, and even airliners, monitor the emergency frequency (PHAK ch. 16).

This is a teaching problem, not a radio problem: declaring an emergency is an appropriate reaction, and AIH ch. 1 assigns teaching that lesson to you by name. Once an emergency is declared, ATC gives the pilot priority handling.

The authority is 91.3, quoted in AIH ch. 1: "In an inflight emergency requiring immediate action, the pilot in command may deviate from any rule of this part to the extent required to meet that emergency."

The other half of the lesson is timing. AIH ch. 1: the learner who hesitates when prompt action is required, or who makes the decision to not decide, has made a wrong decision. Emergencies require the pilot to assess the situation, then choose and execute actions that assure safety.

So the standard you train to is not "declare when out of options" — it is declare while options remain. Students hesitate because they fear paperwork; say out loud that priority handling is the point and the paperwork is not the threat.

RWSL is designed to give a direct indication that it is unsafe to enter a runway, cross a runway, or take off from or land on a runway when the system is activated. Runway incursions develop quickly and without warning during routine traffic situations, leaving little time for corrective action (PHAK ch. 14).

• Runway status lights are red, and they indicate runway status only — they do not indicate clearance to enter a runway or clearance to take off.
• Runway Entrance Lights (REL) warn aircraft crossing or entering a runway from intersecting taxiways that there is conflicting traffic on the runway.
• Takeoff Hold Lights (THL) warn an aircraft in position for takeoff that the runway is occupied and it is unsafe to take off.

The lesson that has to stick: red lights, do not move — even with a clearance. And the converse, which students invert: lights going out is not a clearance.

The Task title includes runway lighting systems, so be ready to teach the whole family, not just RWSL. All of this is PHAK ch. 14.

• VASI — the most common system. Obstruction clearance within 10° of the extended centerline and up to 4 NM from the threshold. Light units in bars: a 2-bar VASI (near/far) gives one glidepath, normally 3°; a 3-bar (near/middle/far) gives two, the upper one ¼ degree above the lower. The whole system rests on red/white color differentiation — white in the upper part of each beam, red in the lower.
• PAPI — same idea, lights in a single row, normally on the left side of the runway. For a 3° glidepath: high more than 3.5°, slightly high 3.2°, on 3°, slightly low 2.8°, low less than 2.5°.
• Tri-color — one light unit: red below, green on, amber above. Teach the trap: descending below the glidepath there is a small dark-amber area students mistake for "above."
• Pulsating — one unit, two colors: steady white on glidepath, steady red slightly below, pulsating red further below, pulsating white above, with the rate increasing the further off you are. Useful range about 4 miles by day, 10 at night.

Teaching angle: demonstrate one approach flown to the indicator and one flown to the aim point, then ask the student which one the airplane agreed with. Mnemonic for VASI/PAPI both — "red over white, you're all right."

Ground the student in colors first, then exceptions (PHAK ch. 14):

• REIL — a pair of synchronized flashing lights on each side of the threshold, for rapid identification of the approach end.
• Runway edge lights — white, classified by intensity as HIRL, MIRL, LIRL. On instrument runways the last 2,000 feet or half the runway, whichever is less, is amber; the runway end is red.
• In-runway — RCLS centerline lights at 50-foot spacing, white until the last 3,000 feet, alternating white/red for the next 2,000, all red for the final 1,000. TDZL run from 100 feet past the threshold to 3,000 feet or midfield, whichever is less.
• Taxiway — edge lights are blue; centerline lead-on/lead-off lights alternate green and yellow. Land and hold short lights are a row of pulsing white lights at the hold short point, on only when LAHSO is in effect.
• Pilot-controlled lighting — key the mike on the published frequency: 7 times in 5 seconds for highest intensity, 5 times for medium, 3 times for lowest. Check the Chart Supplement for which airports and which frequency.
• Beacons — dusk to dawn, most effective 1–10° above the horizon. White and green civilian land airport; white and yellow a water airport; white, yellow, and green a heliport; two quick white flashes alternating with green military.

Seaplane base contrast: the water airport beacon is often the only lighting in the picture. The Seaplane, Skiplane, and Float/Ski Equipped Helicopter Operating Handbook (FAA-H-8083-23) draws the distinction directly — approaching a towered land airport, a pilot can expect the runway to be flat and free of obstructions, with wind and landing direction supplied by the tower; on water, the pilot must judge the safety and suitability of the landing area, evaluate the water surface, determine wind direction and speed, and choose a landing direction. Most established seaplane bases have a windsock, but when none is visible the surface itself supplies the cues. That is why Task VI.B has you teach a landing-area survey rather than a lighting-system lookup.

The method is divided into four phases — explanation, demonstration, learner performance with instructor supervision, and evaluation (AIH ch. 9, the flight-instructor treatment).

Know the other version before an evaluator quotes it at you: AIH ch. 5 splits the same method into five phases — explanation, demonstration, learner performance, instructor supervision, and evaluation. Same content; ch. 9 merges the middle two.

• Explanation — accomplished prior to the flight, with lesson objectives, completion standards, and a thorough preflight briefing. Convey the precise actions the learner will perform and describe the end result. Include safety procedures, and encourage questions before leaving this phase. For radio: write the calls out, in order, on the whiteboard.
• Demonstration — you make the calls and may describe the actions simultaneously (AIH's word is "may"; the ACS skill standard makes it mandatory for you on the checkride), avoiding extraneous activity so the learner gets a clear picture. If the demonstration does not conform to the explanation — the controller gives you something unexpected — acknowledge and explain the deviation immediately.
• Learner performance and supervision — the learner must act and do, and should get the opportunity as soon as possible after the demonstration. Do not let a week pass between the brief and the first call.
• Evaluation — record it, advise the learner of progress, offer concrete suggestions on deficiencies, and avoid ending on a negative note.

Three steps, and the middle one is what separates it from plain demonstration-performance:

1. Instructor tells — instructor does. A carefully planned demonstration with verbal explanation, in the same sequence in which it was explained. This is the only step where the learner is passive. Since learners imitate the instructor, demonstrate the skill exactly the way you expect it to be practiced.
2. Learner tells — instructor does. The learner plays instructor and tells you what to say. Freed from performing, the learner can organize thoughts about the steps, and perceptions begin to develop into insights. You get to evaluate their understanding, and by primacy, correct a misunderstanding before the learner becomes absorbed in controlling the aircraft.
3. Learner tells — learner does. Application. The thinking is done verbally, which forces total concentration and lets you tell whether an error came from a misconception or a lack of motor skill.

For the radio, step 2 is the whole lesson. Sitting in a parked airplane with the learner dictating your calls surfaces every misconception before it costs anyone airspeed.

AIH is blunt: instructors should avoid unnecessary jargon and technical terms their learners do not know, and clearly describe the actions the learner is expected to perform. "Communication is the key. It is neither appropriate nor effective for instructors to try to impress learners with their expertise by using language that is unnecessarily complicated."

Practical translations:

• Sequence the skill in the step-by-step order normally used to perform it.
• Use known to unknown when the new call relates to something already learned — a base call is the downwind call with one word changed.
• Use simple to complex when teaching several skills at once: start with the simplest so the learner gains confidence and is less likely to become frustrated.

The failure mode to avoid is the instructor who demonstrates fluent controller-speak at conversational speed and then wonders why the student sounds nothing like it.

AIH ch. 9 sets both the procedure and the limit.

Procedure. The preflight briefing must include the procedures for the positive exchange of flight controls — a three-step process is the strongly recommended, proven method. When necessary, take the controls and calmly announce, "I have the flight controls."

Why you take them completely. If you allow the learner to remain on the controls, you may not have full and effective control of the aircraft. Anxious learners can be incredibly strong and usually exhibit reactions inappropriate to the situation. If a recovery is necessary, there is absolutely nothing to be gained by fighting the learner for the airplane. This is the paragraph that matters most for a frozen student on the radio, because the freeze and the death grip come from the same place.

The limits. Learners should never be allowed to exceed the flight instructor's limits, and instructors should not exceed their own ability to perceive a problem, decide on a course of action, and physically react within their ability to fly the aircraft.

Usually not. AIH ch. 9: correction of learner errors does not include the practice of taking over from learners immediately when a mistake is made. Safety permitting, it is frequently better to let learners progress part of the way into the mistake and find a way out — "it is difficult for learners to learn a maneuver properly if they seldom have the opportunity to correct an error."

For the radio the calculus is easy, because a garbled call is rarely a safety-of-flight item. Let the learner hear the controller ask them to say again, and let them fix it. Then debrief it.

The exception is the other half of that section: a learner may perform correctly without understanding the principles involved. When you suspect that — a student who reads back "hold short of runway two-seven" perfectly but taxis across it — require them to vary the performance slightly, combine it with other operations, or apply the same elements to another maneuver. A learner who does not understand will not be able to.

The ACS asks you to analyze and correct them, so have both halves ready. Name the error, name the cause, name the fix:

• Frequency not set before it is needed — cause: no place in the flow for it. Fix: tie frequency loading to a geographic trigger, and set radios well in advance of need (AIH ch. 1).
• Flying the airplane second. Cause: fixation, which AIH ch. 3 defines as becoming absorbed in performing one task to the exclusion of other tasks, and notes is often a sign the task has not received enough practice in isolation. Fix: practice the calls on the ground until they are not a task.
• Nonstandard phraseology — cause: imitation of what is heard on the frequency. Fix: primacy, and the Pilot/Controller Glossary (AI.VI.A.S2).
• Reading back a clearance without hearing it — a readback is a check, not a courtesy.
• Stepping on transmissions — the learner does not listen before keying.
• Silence when confused instead of "say again."
• Wrong light-gun column memorized (see the Quick Review table).

Add the interruption failure AIH ch. 3 warns about: a learner interrupted mid-checklist by a radio call returns to a later point in the procedure, omitting one or more steps. Teach a physical place-holder.

Teach the capability honestly so the student neither over-trusts nor ignores it.

What it is. Radar measures the time interval between transmission and reception of radio pulses, correlated with the antenna's angular orientation, to give range, azimuth, and/or elevation (PHAK ch. 14).

Limits worth teaching (PHAK ch. 14):

• Radio waves are bent by temperature inversions, reflected or attenuated by heavy clouds and precipitation, and screened by high terrain.
• Signals degrade over distance and cannot penetrate solid objects such as mountains.
• The fastest radar updates every 4.7 seconds — the target you are being pointed at has moved.
• By contrast, ADS-B satellite signals do not degrade over distance, give better visibility around mountainous terrain, and let equipped aircraft update their own position once a second with better accuracy.

The instructional point: a traffic advisory is a cue to look, not a substitute for looking. Controllers cannot issue advisories on aircraft they cannot see.
