Avtaar is framed in conspiracy by Commanding Officer who is a member of a flying squad (2-5)
I believe the answer is:
co-pilot
'is a member of a flying squad' is the definition.
I can't tell whether this definition defines the answer.
'avtaar is framed in conspiracy by commanding officer' is the wordplay.
'avtaar' becomes 'i' (I can't justify this - if you can you should give a lot more credence to this answer).
'is framed in' indicates putting letters inside.
'conspiracy' becomes 'plot' (I've seen this before).
'by' says to put letters next to each other.
'commanding officer' becomes 'co'.
'i' put inside 'plot' is 'pilot'.
'pilot' after 'co' is 'CO-PILOT'.
'who' is the link.
Can you help me to learn more?
(Another definition for co-pilot that I've seen is " Part of a flight deck team".)
