Air TV broadcast about band, after a pilot (7)
I believe the answer is:
aviator
'pilot' is the definition.
(thesaurus)
'air tv broadcast about band after a' is the wordplay.
'broadcast' indicates anagramming the letters.
'about' is an insertion indicator.
'band' becomes 'o' (I've seen this in other clues**).
'after' says to put letters next to each other.
'air'+'tv'='airtv'
'airtv' anagrammed gives 'viatr'.
'viatr' placed around 'o' is 'viator'.
'viator' after 'a' is 'AVIATOR'.
(Other definitions for aviator that I've seen before include "Aircraft pilot" , "Flyer, pilot" , "Pilot; style of sunglasses" , "Woman in a flying machine" , "Air pilot" .)
