According to the FOM, what are the restrictions on altitude changes during a flight?

Altitude changes during a flight must adhere to specified operational limits and require coordination with Air Traffic Control (ATC). This is essential for ensuring safety and maintaining separation between aircraft. The regulations outlined in the Flight Operations Manual (FOM) would emphasize compliance with air traffic instructions, as they are critical for managing the complex airspace and ensuring that pilots operate within controlled parameters.

By coordinating altitude changes with ATC, pilots contribute to the overall safety and efficiency of the air traffic system. This practice allows ATC to provide the necessary information and ensure that altitude changes do not conflict with other aircraft, especially in busy airspace or during critical phases of flight. Thus, following the specified operational limits reinforces the importance of teamwork and communication in aviation, ultimately helping to prevent accidents and incidents caused by unauthorized or uncoordinated altitude changes.
