Where is the external canopy actuation switch located?

The external canopy actuation switch is located behind door 1111 on the Ladder Access Panel, making this the correct answer. This placement provides ground crew with safe access to operate the canopy without entering the cockpit, allowing for efficient maintenance and safety checks. Such design considerations are vital for both functionality and safety, ensuring that personnel can perform their tasks effectively while minimizing risks. Access through the Ladder Access Panel is also strategically chosen to keep the switch protected and away from potential accidental activation during ground operations.
