Airport Operations, ATC & Communications

Correct

The answer is A: unlawful interference (hijacking)

7500 is the hijack code and 7700 indicates an emergency. VFR gliders use 1202.

Correct

The answer is C: change to 2200 first, then to 7200

When making routine code changes, avoid inadvertently selecting 7500, 7600, or 7700. The AIM example is switching from 2700 to 7200 by going first to 2200 and then to 7200, not to 7700 and then 7200.

Correct

The answer is C: Never; it is reserved for military interceptor operations

The AIM states that under no circumstances should a pilot of a civil aircraft operate the transponder on code 7777; it is reserved for military interceptor operations.

Correct

The answer is B: Only when ATC requests it

Transponder/ADS-B equipment must be operated only as specified by ATC; activate the IDENT feature only when requested by ATC.

Correct

The answer is B: turn on automatic altitude reporting (Mode C)

SQUAWK ALTITUDE means activate Mode C with automatic altitude reporting. STOP ALTITUDE SQUAWK means turn off automatic altitude reporting.

Correct

The answer is B: Turn off altitude reporting and check your altimeter setting

STOP ALTITUDE SQUAWK means turn off automatic altitude reporting. A readout that differs may mean the encoder is wrong or your altimeter is mis-set, so verify the altimeter setting. 'Stop squawk' would be the instruction to stop transponder transmissions.

Correct

The answer is A: standard pressure (29.92 inches Hg)

Altitude encoders are preset to standard atmospheric pressure, so they report pressure altitude. The ATC facility applies the local altimeter correction before displaying it. An incorrect altimeter setting therefore doesn't change the encoded altitude but does change your true altitude.

Correct

The answer is A: Any time the aircraft is on the airport movement area

Aircraft should operate with the transponder in the altitude-reporting mode and ADS-B Out enabled at all airports any time the aircraft is on any portion of the movement area, including taxiways and runways, so surface surveillance systems can see it.

Correct

The answer is B: set code 4512 with altitude reporting, then press IDENT

'Squawk (number) and ident' means operate the transponder on the specified code with altitude reporting enabled and engage the IDENT feature.

Correct

The answer is C: continue the flight under VFR and land as soon as practicable

If the failure occurs in VFR conditions, or VFR conditions are encountered after the failure, the pilot must continue the flight under VFR and land as soon as practicable. The route and altitude rules apply only if the failure occurs in IFR conditions.

Correct

The answer is A: stay outside the Class D until you know the traffic flow, then call your intentions and request light signals

With a receiver failure, remain outside or above the Class D surface area until the direction and flow of traffic are determined, then advise the tower of your aircraft type, position, altitude, and intention to land, and request control by light signals.

Source: AIM 4-2-13 · ACS PA.III.A

Correct

The answer is A: 3 to 5 miles

The AIM says that when approximately 3 to 5 miles from the airport, advise the tower of your position and join the pattern; from then on watch the tower for light signals, and report downwind and/or base if a complete pattern is flown.
