AWOL a question for twr controller....
Quite often in my ga days we'd be cleared a visual approach 'when within your ccl area' (At night)
Was ok out with low lsalts but in places like CNS and even EN it was a bit of challange with a 2.6nm ccl area from 3700+ feet!
Whats the go with that clearance? I would have presumed the guys would know about the profile before issuing the clearance?
