Ultimate Traffic 2 had a feature that would show you the number of landings and takeoffs by the hour, so you could determine the busiest time of day at a specific airport (at least that's what I used it for). The UT feature also allow you to filter the chart by airline and whether the traffic was Commercial or GA.
I think it would be nice to have it (or something similar) in AIGAIM. I usually want to start my flights at airport when they are at their busiest.
