When is it appropriate to communicate aircraft movement intentions to the flight deck?

Communicating aircraft movement intentions to the flight deck once the pushback is initiated is appropriate because this is the point at which the ground crew takes responsibility for directing the aircraft away from the gate. Clear communication at this stage ensures that both the ground crew and the flight deck are aligned on the movements to be made, enhancing safety and coordination.

During pushback, it's critical to establish clear communication so the pilots are aware of the ground crew's actions as they maneuver the aircraft. This communication helps avoid misunderstandings and ensures proper sequencing with other ground traffic, as well as prepares the flight crew for any necessary preparations for taxiing or takeoff.

While communication may occur at other points during the flight operations, such as after landing or during taxi, these moments do not focus on the specific coordination related to pushback procedures. Therefore, initiating communication at the time of pushback represents the most appropriate point to ensure safety and clarity of movement intentions.
