Which of the following will not detach the slide/liferaft?

• A. Pulling yellow manual inflation handle
• B. Automatic detachment in emergency
• C. Pulling red manual inflation handle
• D. Jettison lever

Answer: (C)

Detachment versus inflation controls for an emergency slide/raft is the key idea. Detachment happens when the slide is released from the door either automatically in an emergency or via the manual jettison mechanism. The inflation controls, on the other hand, are there to inflate the slide or raft after it’s detached or deployed—they don’t release the slide from the aircraft.

In this system, the red manual inflation handle is used to inflate the raft/slide and does not trigger detachment. The other actions can lead to detachment: automatic detachment occurs when the door is opened in an emergency and the slide deploys, and the jettison lever is a deliberate release to detach the slide from the door. The yellow manual inflation control is associated with the detachment pathway in this configuration, so pulling it would result in detachment rather than simply inflating.

So, pulling the red manual inflation handle will not detach the slide/liferaft.
