ATC says: "Globe Air 345, line up and wait runway 23 left." What is the correct response?
- ALine up and wait runway 23 left, Globe Air 345.
- BGlobe Air 345 line up.
- CLine up runway 23, Globe Air 345.
- DGlobe Air 345 line up and wait runway 23 left, awaiting take-off clearance.
Why that is the answer
'Line up and wait' is a safety-critical instruction that is read back in full, including the runway designator, followed by the call sign.
- Runway-related instructions such as 'line up and wait' must be read back in full under ICAO Annex 10 Vol II, because entering a runway is safety-critical.
- The readback repeats the instruction and the runway exactly, ending with the call sign: 'Line up and wait runway 23 left, Globe Air 345.'
- The designator '23 left' must be retained, as reading back only '23' could be actioned on the wrong parallel runway.
- Option B ('Globe Air 345 line up') is wrong because it drops both 'and wait' and the runway designator, so it is not a valid readback.
- So the correct answer is A — Line up and wait runway 23 left, Globe Air 345.

A TCAS RA requires deviating from ATC clearance. How should the pilot report this? Call sign plus...
- A"TCAS Conflict".
- B"TCAS Alert".
- C"TCAS RA".
- D"TCAS TA".
Why that is the answer
When a TCAS RA forces you off clearance you tell ATC with your call sign plus 'TCAS RA'; a TA is only advisory and does not prompt this report.
- A resolution advisory (RA) commands a vertical manoeuvre, climb or descend, that may take you off your assigned ATC clearance, so the controller must be told the moment you begin to follow it.
- The standard phrase is the call sign followed by 'TCAS RA', for example 'BIGJET 591, TCAS RA', which tells ATC you are manoeuvring in response to the ACAS and are momentarily not following clearance.
- When the encounter is over you report 'CLEAR OF CONFLICT, RETURNING TO...' or 'CLEAR OF CONFLICT, ...RESUMED' so the controller knows you are back on your clearance.
- Option D ('TCAS TA') is wrong because a traffic advisory only alerts you to nearby traffic, requires no manoeuvre and is not reported to ATC; only an RA prompts this report.
- So the correct answer is C — 'TCAS RA'.

How much of the Radio Telephony paper is ATC Communications and Readback?
The DGCA does not publish a per-chapter breakdown of its papers, so nobody can honestly tell you — and we will not guess. What we can tell you is what students who have just sat a paper reported meeting, which is measured rather than rumoured: that is the exam recall report inside the app.
What is the best way to revise ATC Communications and Readback?
Sit a short timed set on this chapter alone, tag how sure you were of each answer, then drill the two that actually leak marks: the ones you got right while guessing, and the ones you got wrong while confident. Avielevate does that tagging for you and puts anything you got wrong back in front of you on a spaced schedule.
