Left tights off for check-up (6,4)

I believe the answer is:

flight test

'check-up' is the definition.
(a flight test checks if something works)

'left tights off' is the wordplay.
'off' indicates an anagram.
'left'+'tights'='lefttights'
'lefttights' is an anagram of 'FLIGHT TEST'.

'for' acts as a link.

I've seen this clue in The Guardian.
