Shows pilot and flight attendants the propeller (8)
I believe the answer is:
airscrew
'propeller' is the definition.
(I know that airscrew is a type of propeller)
'shows pilot and flight attendants' is the wordplay.
'shows' becomes 'airs' (shows on TV).
'pilot and flight attendants' becomes 'crew' (I've seen this in another clue).
'airs'+'crew'='AIRSCREW'
'the' is the link.
(Other definitions for airscrew that I've seen before include "whirling blades" , "Plane's propeller" , "means of propulsion" , "Part of plane" .)
