Interesting about the red X's. I've used different browsers and have yet to recreate. The forum is operated by XMB, so I've not much knowledge in the inner-workings of the code behind it. I'll definately be looking into that.
A lot of the numbers for the aircraft were thrown together, and will be tweeked during beta testing. There are a few numbers you can't see, however, such as a fixed cost applied for each take-off and landing. To calculate the turn times, we used several factors such as, powerplant (turboprop/jet), seats, and typical range. The 747 and A380 both max out the equations. The reason being most 747 flights are international with long catering, fuel, cleaning, and boarding times. Granted, none of these equations have been tested yet. That's what beta is for. I see what you mean about the 328 and 328jet. I'm skeptical about the 328prop price, but can't remember what source the info came from, so I'll have to do some more research.
Thanx for the input! Keep the suggestions coming.
