What is important to confirm when the airstair is extended?

When the airstair is extended, it is crucial to ensure that there are no obstructions around. This is important for the safety of passengers and crew members who will be using the airstair to board or disembark from the aircraft. Confirming that the area around the airstair is clear helps prevent accidents or injuries that could occur if someone were to accidentally trip over an object or if there were any unexpected obstructions that could hinder a safe exit or entry.

While locking the airstair is also important for stability and safety, the immediate priority upon extension is to ensure the area is free of any hazards. Weather conditions are relevant for overall flight operations, and the speed of the plane is not applicable when the airstair is being extended, as it is typically done when the aircraft is stationary on the ground. Therefore, the focus should be on the surrounding environment.
