When should a pilot confirm assigned altitude on initial contact?

Confirming assigned altitude on initial contact is essential for clear communication and safety in aviation operations. Pilots should confirm their assigned altitude especially when it has not been explicitly stated. This practice ensures that both the pilot and air traffic control are aligned on the expected altitude, which reduces the risk of misunderstandings that could lead to altitude deviations. It is particularly crucial in busy airspace or during complex air traffic situations where clarity is paramount.

In contrast, if an altitude is clearly stated in the initial instruction, repeating it back becomes redundant. Thus, the emphasis on confirming assigned altitude only when it has not been stated helps streamline communications without sacrificing safety.
