What must personnel ensure before the aircraft is chocked?

Before an aircraft is chocked, it is critical that all personnel are in their positions to ensure safety and proper handling of the aircraft. Chocking the aircraft is a step that secures it in place and prevents it from moving. If personnel are not in their designated positions, there is a risk of accidents occurring during this procedure, as someone may be in harm's way or not able to respond appropriately to an emergency situation.

While other factors, such as completing maintenance checks or ensuring sufficient fuel levels, are important for the safe operation of an aircraft, the immediate priority before the aircraft is secured with chocks is to ensure that all personnel are safely positioned. This enhances safety by making sure that everyone involved in the operation is aware and prepared for the steps that follow. Stable weather conditions can also be a consideration, but they do not directly relate to the critical safety of personnel at the moment of chocking the aircraft.
