Part 4/8:
Pushback is one of the initial steps before a flight can actually take off, and it involves reversing the aircraft away from the gate. The transcript reflects this operational phase well, as multiple aircraft, such as US Air 1973 and FedEx 369, communicate their pushback readiness.
For example:
Continental 842: "Push back company discretion, let me know when you're ready for the taxi."
US Air 1973: "We're ready to push gate 37."
This exchange illustrates the procedures involved in pushback and taxi operations, requiring pilots to confirm readiness and then wait for instructions from the ground control.
