Aviation Phraseology & Standard Terminology Flashcards

When a pilot transmits 'UNABLE' in response to an ATC instruction, it means:

Answer: The pilot cannot comply with the clearance or instruction for any reason

'Unable' is the standard term to inform ATC the pilot cannot comply with an instruction, regardless of the reason.

In aviation phraseology, 'STANDBY' means:

Answer: Wait — I will call you back

'Standby' instructs the pilot to wait for further contact; it does not require a full readback or continued acknowledgment.

When a pilot reports 'FINAL' during a traffic pattern, it indicates:

Answer: The aircraft is aligned on the final approach course to the runway

Reporting 'final' indicates the aircraft has turned onto the final approach leg and is aligned with the landing runway.

The instruction 'CONTACT DEPARTURE on 124.7' requires the pilot to:

Answer: Switch to 124.7 and initiate two-way communication with departure control

When instructed to 'contact' a facility on a given frequency, the pilot must switch to that frequency and actively initiate communication.

What does the ATC phrase 'RESUME NORMAL SPEED' signify?

Answer: Cancel all previously assigned speed restrictions

'Resume normal speed' cancels any speed restrictions previously assigned by ATC, allowing the pilot to fly appropriate speeds at their discretion.

Standard aviation phraseology uses 'AFFIRM' instead of 'YES' primarily because:

Answer: It is less likely to be misunderstood over noisy or distorted radio channels

Standard phraseology reduces the chance of misunderstanding; 'affirm' is phonetically distinct and less likely to be confused with other sounds under poor radio conditions.

Which element is NOT typically included in a standard en route position report?

Answer: Number of passengers on board

Standard en route position reports include identification, position, time, altitude, and next position with ETA — passenger count is not part of the report.
