How do you request an altitude assignment verification in level flight?

Requesting confirmation of the assigned altitude is crucial when ensuring effective communication and maintaining safety during flight operations. When an air traffic controller wants to confirm that an aircraft is maintaining the correct altitude, the phraseology used needs to be clear and unambiguous. By explicitly asking for confirmation of the assigned altitude, the controller is seeking assurance from the pilot that they are at the correct altitude as per the last instruction given.

This kind of request is particularly important in level flight, as it helps to prevent altitude deviations that could increase the risk of conflicts with other air traffic. It emphasizes the mutual responsibility of both pilot and controller to maintain safe vertical separation.

In contrast, requesting to hold the current altitude may imply that the controller wants the pilot to remain at that altitude without specifically confirming if they are already there. Asking the pilot to report altitude simply puts the onus on the pilot to provide that information without a direct verification request. Similarly, requesting details about the aircraft is unrelated to altitude verification and does not address the current need for expedited communication regarding altitude compliance.
