Vintage ATCO,
first thank you for your time.
I've just checked my original posting and realised that I misused phrase "24/7". What I ment is "whenever there is t/o or ldg". I realy don't care if they turn everything off and take a coffee brake in idle periods.
I also think the table is for licencing. Finaly, during night would you turn all the lights on (including TDZ lights) few minutes (or 15 as cAP says) before estimated ldg time or not?
