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

• A. 10 seconds
• B. 15 seconds
• C. 20 seconds
• D. 25 seconds

Answer: (B)

When you’re being vectored for a final approach on ASR FINAL and you don’t hear any transmissions, you pause for a short, defined time before trying again. The recommended wait is fifteen seconds. This interval gives ATC time to respond, re-acquire you on their radar, or issue further instructions, and it also helps prevent crowding the frequency with rapid repeated calls. After waiting, reattempt contact on the assigned frequency while continuing to follow the current vectors and altitude guidance. If contact still can’t be established, follow the established missed-approach or failure procedures.
