Which action is NOT part of the final preparation for taxi-out commands?

In the context of final preparations for taxi-out commands, performing cabin checks is not explicitly part of the actions needed at that moment. Final preparations typically focus on ensuring that all safety measures and systems are ready for the aircraft to move on the ground.

Cabin checks are often performed earlier in the pre-flight process to ensure that everything inside the cabin is secure and that safety protocols are adhered to, but as the aircraft is preparing to taxi, the emphasis shifts to immediate readiness tasks such as cross-checking the status of doors and waiting for the all call from the cabin crew to confirm that everyone is ready for departure.

Therefore, while cabin checks are important, they are not considered a specific action taken during the final preparation phase just before taxiing.
