What does the "enroute phase" not include?

The enroute phase of flight encompasses the period where the aircraft is flying between the departure airport and the destination airport after reaching cruising altitude. This includes aspects such as climbing to cruising altitude and maintaining that altitude during the majority of the flight. Additionally, cruising at a constant altitude is a key component of this phase, as it signifies the stable cruise operation after the aircraft has ascended.

Landing and final approach procedures, however, occur after the enroute phase is complete. These procedures are part of the landing phase of flight, which is distinct from the enroute phase focusing on travel between departure and destination airports. Understanding the boundaries of these phases is essential for the safe and effective management of flight operations.
