While on a VFR flight, Air Traffic Control (ATC) instruct you:

‘Golf Delta Juliet, squawk conspicuity’

What code should be set, and what should your reply be?

  • A

    You would set squawk 2000, and reply: Squawk conspicuity, Golf Delta Juliet

  • B

    You would set squawk 7000, and reply: Squawk conspicuity, Golf Delta Juliet

  • C

    You would set squawk 2000, and reply: Squawk 2000, Golf Delta Juliet

  • D

    You would set squawk 7000, and reply: Squawk 7000, Golf Delta Juliet

In aviation, squawk conspicuity refers to the act of setting the transponder code to

  • 7000 for VFR (Visual Flight Rules) flights or
  • 2000 for IFR (Instrument Flight Rules) flights when no specific code has been assigned by air traffic control (ATC).

This allows ATC to easily identify and track aircraft, particularly in areas where they are not actively managing traffic.


Looking at the answer options:

You would set squawk 2000, and reply: Squawk conspicuity, Golf Delta Juliet --> INCORRECT. VFR is 7000.

You would set squawk 7000, and reply: Squawk conspicuity, Golf Delta Juliet --> CORRECT.

You would set squawk 2000, and reply: Squawk 2000, Golf Delta Juliet --> INCORRECT. VFR is 7000

You would set squawk 7000, and reply: Squawk 7000, Golf Delta Juliet --> INCORRECT. The correct radio response is to read back exactly as ATC gave you the instruction, and so say 'squawk conspicuity' and not the actual code number.
