Light fixture that helps passengers leaving the plane (9)
I believe the answer is:
parachute
'that helps passengers leaving the plane' is the definition.
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for parachute that I've seen before include "Drop from plane" , "Equipment to break a fall from the sky" , "Devise for making descent from an airplane" , "Eat up char for something to break your fall" , "Equipment for making a descent from an airplane" .)
