ATPL Air Traffic Control Practice Test 2025 – The Complete All-in-One Guide for Exam Success!

When a pilot is vectored across the final approach course during an IFR approach, the appropriate action is to contact approach control to notify them of this situation. This communication is crucial as it allows air traffic controllers to assess the aircraft's position and intentions, ensuring safety and proper sequencing with other traffic that may be on approach.

Notifying approach control helps maintain situational awareness, both for the pilot and for air traffic control, allowing for timely adjustments to the flight path if necessary. This interaction can prevent potential conflicts or misunderstandings about the intended approach procedure, keeping the operation safe and efficient.

Remaining on the last heading or returning to a previously assigned altitude without notifying approach control could lead to confusion or potential safety risks, as the exact situation regarding other aircraft on final approach may be unknown. Therefore, contacting approach control is the best course of action in this scenario.
