RAF man on light duty? (5)
I believe the answer is:
pilot
This clue might be a double definition.
'raf man' is the first definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'light duty?' is the second definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'on' acts as a link.
Can you help me to learn more?
(Other definitions for pilot that I've seen before include "Ship's guide" , "Plane operator" , "Steer, test (scheme)" , "trial episode" , "Flier or helmsman" .)
