Equipment that checks aircraft on carriers (8,4)

I believe the answer is:

arrester gear

I'm a little stuck... Click here to teach me more about this clue!

'carriers' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'equipment that checks aircraft on' is the wordplay.
'equipment' becomes 'gear' (gear is a kind of equipment).
'that checks aircraft' becomes 'arrester' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'on' says to put letters next to each other.
'gear' after 'arrester' is 'ARRESTER GEAR'.
