My apology for the bandwidth on this one. I just never noticed that checkbox with the time of day/night for the flight dialog.
Again, I appreciate your help ... I think I've done 50+ flights, last night was LGA to DTW, then MBS to ORD. Learning something new with every flight.
I have not started upgrading the 737 for XP12, but it already "runs" in it.
The other variants are not going to be part of the version 1 run, but we are not ruling out doing a V2 at a later time with greatly enhanced extra functionality and variants.
