What are the PDIs on the loudhailer?

The correct choice involves several critical steps to ensure the loudhailer is fully operational and safe for use. Firstly, checking stowage ensures that the loudhailer is properly secured in its designated location, preventing it from becoming a projectile during flight. Squeezing the handle is a practical means to test whether the device is functioning, as it typically activates the loudhailer. Finally, looking for a green light serves as a visual confirmation that the device is powered and operational. Each of these steps plays an essential role in verifying the loudhailer’s readiness for use in emergency situations, aligning with safety protocols and best practices for aircraft emergency equipment.

Other options simplify the checks inappropriately or focus on incomplete assessments, which could jeopardize safety during an actual emergency, underscoring the importance of thorough checks as outlined in the correct choice.
