What is the first step after pulling the door operating handle up during MED operation?

The first step after pulling the door operating handle up during a Manual Emergency Door (MED) operation involves pushing the door out through the door frame. This action is crucial because it helps to ensure that the door is fully opened and separated from the aircraft’s fuselage, which is essential for a safe and effective evacuation.

Once the handle is pulled, pushing the door out is the next logical step in the process to facilitate an unobstructed exit for passengers and crew. It aligns with the procedure designed to open the door against any potential resistance created by the cabin pressure or other factors, allowing for a clear pathway in an emergency scenario.

Moving directly to the subsequent actions, such as waiting for the slide to inflate or checking for obstructions, is important but only after the door is effectively opened. This sequence ensures that all necessary safety measures are adhered to, contributing to the overall efficiency and safety of the emergency evacuation process.
