Temporary setback as male dropped from aircraft (4)
I believe the answer is:
blip
'temporary setback' is the definition.
(I've seen this before)
'male dropped from aircraft' is the wordplay.
'male' becomes 'm' (common abbreviation).
'dropped from' is a deletion indicator.
'aircraft' becomes 'blimp' (blimp is a kind of aircraft).
'blimp' with 'm' taken out is 'BLIP'.
'as' acts as a link.
(Other definitions for blip that I've seen before include "Temporary setback - short high-pitched sound" , "Glitch" , "Unforeseen irregularity" , "Momentary deviation" , "Temporary exception" .)
