When expecting an altitude change, how should a pilot be informed?

The correct answer emphasizes the importance of communication and coordination between pilots and air traffic control when it comes to altitude changes. In aviation, pilots must be informed ahead of time about when to expect climb or descent clearances. This advance notice allows pilots to prepare their aircraft and adjust their flight plans accordingly. Additionally, notifying the appropriate facility about the desired altitude change ensures that all parties are aware and that the airspace is managed safely.

While sequencing through different steps during altitude changes is crucial, simply waiting for an approved change or checking with the next facility does not provide the proactive approach needed to ensure a smooth transition between altitudes. Requesting an altitude change only from another facility without prior knowledge of when to expect it may lead to misunderstandings or conflicts in airspace management. Thus, the emphasis on knowing when to expect clearance and coordinating properly is key in aviation operations.
