When is a controller required to advise a pilot if the purpose of a radar vector?

• A. After the vector is completed
• B. When initiating the vector
• C. Only if requested by the pilot
• D. If the vector exceeds 5 minutes

Answer: (B)

When you issue a radar vector, you should tell the pilot the reason for that vector at the moment you initiate it. This gives the pilot immediate context for the turn or heading they’re being assigned and helps them understand why ATC is guiding their path—whether it’s to maintain proper separation, sequence for another arrival, or align with a final approach. Knowing the purpose from the start keeps the pilot oriented and ready for subsequent instructions. Waiting to explain the purpose after the vector is underway isn’t as effective, because the reason for the maneuver can be forgotten or misunderstood as the aircraft adjusts. It’s not required to wait for the pilot to request this information, and there isn’t a standard rule about a five-minute limit driving the need to advise. The guiding idea is to establish the purpose right when the vector begins so the pilot can comply confidently.
