Is it a daylight only requirement to do the flightcheck?
Correct geh065. And in VMC. Its not just a matter of flying down the ILS. A lot of it is off scale laterally and vertically checking for course reversal etc. Visual positioning for the next run cuts down the time a lot as well.
Yeah I can, how about 05:00 - 06:00?
You think its not relatively busy then? A quick check shows every morning this past week there were ~25 arrivals between 0530 and 0630.
