If no transmissions are received on PAR FINAL while vectored, you should wait for how many seconds before attempting contact?

• A. 5 seconds
• B. 10 seconds
• C. 15 seconds
• D. 20 seconds

Answer: (A)

When guiding an aircraft to a PAR final, two-way radio communication is essential for keeping positions and instructions clear. If you’ve vectored the aircraft to final and you don’t hear any response, you pause briefly before trying again. A short pause gives the pilot time to hear your instruction, respond, and for the frequency to clear so your next call isn’t garbled or overlapped. Five seconds is the standard interval because it balances promptness with giving the aircraft a moment to react; it keeps the approach flow moving without unnecessary delay. Waiting longer than that would slow the approach and potentially disrupt sequencing, while a shorter pause might not be enough time for a reply in a busy comms environment. After the pause, you would reattempt contact with a clear instruction.
