Emergency Procedures: DGCA Radio Telephony (R/T) questions

A few emergency facts have to come without thinking: which frequency, which call has priority and what overrides ATC. 121.5 MHz is the international aeronautical emergency frequency.

Across 22 questions, this set leans on frequencies, priority order and warning systems more than message wording. Exam sessions have included 8 of these emergency questions.

Do not confuse 121.5 MHz with 123.45 MHz, the air to air frequency between pilots. SSR interrogates on 1030 MHz and the aircraft replies on 1090 MHz, not the reverse. Priority runs distress, urgency, direction finding, then flight safety. Respond to a GPWS terrain warning at once, ahead of a conflicting ATC instruction.
