Deceptive alien, or aircraft controller? (7)
I believe the answer is:
aileron
'aircraft controller?' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe there's an association between them I don't understand?
'deceptive alien or' is the wordplay.
'alien or' anagrams to 'AILERON'.
However, I'm unsure how this is indicated.
Can you help me to learn more?
(Other definitions for aileron that I've seen before include "Lateral control in aircraft" , "Wing control flap" , "Near oil (anag)" , "Aircraft control surface" , "Trailing-edge flap" .)
