Having to do so makes a pilot a bit dejected (5)
I believe the answer is:
eject
'having to do so makes a pilot a' is the definition.
I can't judge whether this definition defines the answer.
'bit dejected' is the wordplay.
'bit' indicates the answer is hidden within the clue (I've seen 'bit of' mean this).
'EJECT' is hidden within 'dejected'.
Can you help me to learn more?
(Other definitions for eject that I've seen before include "Deport" , "Throw out (e.g. of plane)" , "Throw out forcibly" , "exile" , "Evict" .)
