Remote RAF manoeuvre (3)
I believe the answer is:
far
'remote' is the definition.
(similar in meaning)
'raf manoeuvre' is the wordplay.
'manoeuvre' indicates an anagram.
'raf' with letters rearranged gives 'FAR'.
(Other definitions for far that I've seen before include "A long, long way to go" , "Distant" , "Remote" , "Very much" , "At a great distance way" .)
