When can personnel approach the aircraft cargo doors after it has stopped?

Personnel can approach the aircraft cargo doors only when the engines have spooled down and the beacon light has been turned off to ensure safety. The spooling down of the engines indicates that they are no longer generating thrust and are safe for personnel to approach. The beacon light serves as an important visual signal that alerts ground crew of potential hazards associated with engine operation. When these conditions are met, it is safe to assume that the aircraft is secure and that ground personnel can conduct their tasks without risk of injury or accidents. This protocol is crucial for maintaining safety in the aircraft environment, where moving parts and engine operations can pose significant dangers.
