Absolutely -- at my home airport, for example, runway 14/32 (10,000 ft) has a significant hump in the middle. We have one old 727 that flies up north to Baffin Island every day, loaded so that it can barely climb. You can tell it's starting its takeoff roll because you see a cloud of smoke over the horizon -- a few moments later, the plane itself comes into view, struggling its way off the runway with the nose hanging high in the air. With all the drag, we give that one at least three minutes (instead of the normal two) when it takes off across our runway. The problem is that we're not generally getting that right now anyway -- we're just getting incorrect elevations. All the best, David _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
