Q1. What is the correct way to transmit the number 500 in RT phraseology?
  • A.  Five hundred
  • B.  Five zero zero
  • C.  Five-oh-oh
  • D.  Five hundred hundred
Show answer & explanation
✓ Answer: A. Five hundred
Whole hundreds and thousands are spoken as the number followed by the word 'hundred' or 'thousand', so 500 is 'five hundred'. Numbers that are not round hundreds/thousands are transmitted digit by digit instead.
Q2. When joining the circuit at an aerodrome with an Air/Ground Communication Service (AGCS), what is the correct term to use when asking for traffic information before joining overhead?
  • A.  "Traffic"
  • B.  "Airfield information"
  • C.  "Request join"
  • D.  "Circuit details"
Show answer & explanation
✓ Answer: C. "Request join"
The standard R/T call to obtain joining instructions and traffic information from an AGCS or ATSU is "request join", giving your position, level and intentions. "Airfield information" is not a defined CAP413 phrase, and "traffic" alone is used only when reporting or requesting specific conflicting traffic, not a full join request.
Q3. A pilot reads back a level clearance incorrectly and the controller does not notice the error (a 'hearback' failure). Who bears ultimate responsibility for the safety of the flight if a level bust results?
  • A.  The pilot-in-command, though the controller shares responsibility for correcting an incorrect readback if noticed
  • B.  The controller alone, since ATC issued the original clearance
  • C.  Neither party, as hearback errors are considered unavoidable system limitations
  • D.  The pilot's employer or flying school administration
Show answer & explanation
✓ Answer: A. The pilot-in-command, though the controller shares responsibility for correcting an incorrect readback if noticed
The pilot-in-command remains responsible for flying the correct clearance, but CAP 413 places a duty on controllers to listen critically to readbacks and correct any discrepancy immediately — this shared safety net is why full, clear readbacks matter so much.
