Picked up flight goggles (6)
I believe the answer is:
stares
'goggles' is the definition.
(I've seen this in another clue)
'picked up flight' is the wordplay.
'picked up' indicates a 'sounds like' (homophone) clue.
'flight' becomes 'stairs' (flight of stairs).
'stairs' is a homophone of 'STARES'.
(Other definitions for stares that I've seen before include "Assert with long looks" , "Looks hard" , "Looks lengthily at" , "Long gazes" , "Looks fixedly" .)
