Q21. In the event of distress the correct radiotelephony distress ATC Phraseology is?
Correct answer is C – MAYDAY MAYDAY MAY DAY. Explanation: MAYDAY is the internationally recognized spoken distress signal indicating grave and imminent danger that requires immediate assistance.
Q22. What phrase should precede an urgency communication?
Correct answer is C – PAN PAN. Explanation: PAN PAN is the urgency signal used when an aircraft or crew needs help of a non-immediate nature (lesser than distress but more than routine).
Q23. Distress traffic must normally be maintained on:
Correct answer is C – The frequency where distress was first established. Explanation: Distress traffic should remain on the frequency where distress was initiated to help all relevant parties coordinate.
Q24. How many times is “MAYDAY” usually spoken at the beginning of a distress call?
Correct answer is C – Three. Explanation: Three times (“MAYDAY, MAYDAY, MAYDAY”) is the standard protocol for clarity and to get immediate attention.

Correct answer is C – Any other station receiving the call. Explanation: If not acknowledged by the station called, any other station that hears the call must assist.
Q26. Which of the following is a distress condition?
Correct answer is C – Losing height , no thrust. Explanation: Serious loss of height threatens flight safety and demands immediate help, placing it in the distress category.
Q27. What is the main difference between distress and urgency?
Correct answer is C – Distress needs immediate help; urgency does not. Explanation: Distress requires immediate help (e.g., fire, major malfunction), while urgency is serious, but not immediate (e.g., sick passenger).
Q28. What priority does distress traffic have on air-ground frequencies?
Correct answer is C – Absolute/First priority. Explanation: Distress traffic always takes absolute priority; nobody else should transmit on that frequency unless assisting.
Q29. If a station is controlling distress traffic, what authority does it have on frequency use?
Correct answer is B – May impose silence on others. Explanation: The station in control of distress can order all others to stop transmitting to clear the frequency for the emergency.
Q30. The correct phrase for the urgency signal is pronounced:
Correct answer is B – PAN PAN. Explanation: The urgency signal “PAN PAN” is pronounced as “PAHN PAHN”, similar to the French word “panne.”
Q31. When does the requirement to inform the aircraft operator during urgency apply?

Q32. What information is not essential in a distress call?
Correct answer is C – Name of Pilot. Explanation: Current weather is not mandatory in a distress call; items like position, identification, and nature are more important.
Q33. Which frequency is commonly used as a VHF distress frequency?
Correct answer is B – 121.5 MHz. Explanation: 121.5 MHz is the internationally designated VHF emergency and distress frequency.
Q34. What should other stations do after hearing a distress call and being unable to assist?
Correct answer is C – Maintain listening watch. Explanation: If you can’t help during a distress transmission, you must at least maintain listening watch in case help is needed.
Q35. If an aircraft is no longer in distress, it must:
Correct answer is B – Transmit a distress cancelation message. Explanation: When the aircraft is no longer in distress, they must transmit a message canceling the distress.
Q36. What does “DISTRESS TRAFFIC ENDED” signify?
Correct answer is C – Distress condition is over; silence is lifted. Explanation: “DISTRESS TRAFFIC ENDED” tells everyone the frequency is released and silence is over.
Q37. What phrase should be used to impose radio silence during distress?
Correct answer is A – SILENCE MAYDAY. Explanation: To order silence, the controlling station uses “STOP TRANSMITTING” along with “MAYDAY.”
Q38. What condition does NOT justify an urgency call?
Correct answer is C – Minor technical snag. Explanation: A minor technical snag is routine, not urgent; urgency covers sick passengers, minor failures, etc., but not distress-level cases.
Q39. Urgency traffic has what level of priority?
Correct answer is C – Lower than distress, higher than routine traffic, above VIP. Explanation: Urgency traffic has priority below distress but above normal/routine traffic.
Q40. How distress and urgency messages be transmitted?
