When should the cabin door be cracked open during provisioning?

The cabin door should be cracked open after the doors are disarmed because this step is part of the safety protocol for preparing the cabin for passenger boarding or deplaning. Disarming the doors ensures that the emergency slide systems are not activated inadvertently, making it safe to open the doors for provisioning and allowing crew members to control the cabin environment effectively.

Cracking the door at this stage also allows fresh air into the cabin and assists with the preparation for passenger movement while keeping safety as the foremost priority. The timing is critical to ensure that everything is secured before opening the doors, helping prevent any potential incidents that could arise from opening the cabin door while it is still armed.

Opening the door too early could create safety risks, and waiting until instructed by the pilot could delay the boarding or deplaning process unnecessarily. Therefore, the procedure dictates that the door must be cracked only after the appropriate safety measures have been followed.
