DGCA CPL Radio Telephony — question bank and syllabus
Radio Telephony (RTR(A)) — phraseology, standard words and numbers, distress and urgency, and the regulatory framework behind the licence examined orally alongside your CPL theory.
What is in this paper
Every chapter we cover for Radio Telephony, with how many questions sit behind each one.
These counts come straight out of the question bank and are regenerated whenever it changes —
they are not a claim, they are what is there today.

060137 · Distress, Urgency and Communication Failure
VFR flight, you suspect receiver failure (can't hear others but they can hear you). How do you proceed?
- ASay it twice on the first call, then transmit normally.
- BPreface each call with "Transmitting blind due to receiver failure" and state intentions, only on first call.
- CSay it twice on the first call only.
- DPreface each call with "Transmitting blind due to receiver failure" and state intentions, on every call.
Why that is the answer
With a suspected receiver failure, transmit blind on EVERY call, prefacing each with 'transmitting blind due to receiver failure' and stating your intentions, since you cannot hear any reply.
- A receiver failure means others can hear you but you cannot hear them, so you must transmit blind and cannot rely on any acknowledgement.
- ICAO procedure is to preface each transmission with 'TRANSMITTING BLIND DUE TO RECEIVER FAILURE' and to pass your position and intentions so ground stations and other traffic can build a picture.
- This preface goes on EVERY call, not just the first, because a station tuning in later must still be told why you never answer.
- Option B is the trap: it uses the correct phrase but limits it to the first call only, which leaves later listeners unaware of the failure.
- So the correct answer is D — preface each call with 'Transmitting blind due to receiver failure' and state intentions, on every call.
060153 · Standard Phraseology and Message Construction
Under FIS with a single radio, you need to contact another station for an ATC clearance. What phraseology should you use?
- AG-ACZG, changing to ONE TWO FIVE POINT SEVEN SEVEN FIVE.
- BG-ACZG, request contact ONE TWO FIVE POINT SEVEN SEVEN FIVE.
- CG-ACZG, request monitor ONE TWO FIVE DECIMAL SEVEN SEVEN FIVE.
- DG-ACZG, request change to ONE TWO FIVE DECIMAL SEVEN SEVEN FIVE.
Why that is the answer
To leave one frequency for another for a clearance you request the change; frequencies are spoken with the word DECIMAL between the numbers.
- When you wish to move to another station's frequency you ask permission with 'request change to', giving your call sign first.
- ICAO Annex 10 Vol II sets the decimal point in a frequency as the spoken word 'DECIMAL', so 125.775 is 'ONE TWO FIVE DECIMAL SEVEN SEVEN FIVE'.
- The full transmission is: 'G-ACZG, request change to ONE TWO FIVE DECIMAL SEVEN SEVEN FIVE.'
- Option A ('changing to ... POINT SEVEN SEVEN FIVE') is wrong twice over: it announces rather than requests, and it says 'POINT' instead of the standard 'DECIMAL'.
- So the correct answer is D — G-ACZG, request change to ONE TWO FIVE DECIMAL SEVEN SEVEN FIVE.
060284 · ATC Communications and Readback
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.
060367 · ATC Communications and Readback
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'.
