Aggressive behaviour at elevated level? (3,4)
I believe the answer is:
air rage
'aggressive behaviour at elevated level?' is the definition.
I can't tell whether this defines the answer.
'behaviour at elevated level?' is the wordplay.
'behaviour' becomes 'air' (air is a kind of behaviour).
'at' is a charade indicator (letters next to each other).
'elevated level?' becomes 'rage' (I can't justify this - if you can you should give a lot more credence to this answer).
'air'+'rage'='AIR RAGE'
Can you help me to learn more?
(Other definitions for air rage that I've seen before include "heightened anger?" , "high aggression" .)
