I have a FSPainter 737-800 that I painted and when she kept over-flying the runway and doing missed approaches, etc. I supplemented the original .air & aircraft.cfg files with the defalult B734 she seemed to do fine in landing, so I then adjusted the contact points so she wouldn't be sunken into the ground. Well, today I watched the same aircraft bob up & down as she approached the runway. It would pull-up dramatically and then dive down and continue to do this. The first time it did a missed approach and when she came around again she did the exact same thing but this time she dove towards the runway and hit it and disappeared.  What is wrong with the aircraft? The weather was clear and winds calm..............I've never seen an AI act that way..............

Thanks Rollerball, I'll give it a shot..............

I was thinking about this again and I remembered that when I was doing the fde for the Mustang AI, just before it arrived I had a default Caravan amphibian approaching. I could watch it for several minutes and it did exactly what you said the whole way in from when it came into sight (something like 8 or 9 miles) until it turned finals.

So there ya go - even M$ programmers don't necessarily get it right!

Well most a/c on final on a straight in ILS approach will fly it good with nothing more than the typical hard landing of all AI aircraft, lol. But, the Cessnas, Caravans, Pipers, and the VFR turboprops will often fly too low around the corner of a 90degree approach, then turn hard right/left to land, shoot up to catch glidescope, overfly it, etc etc etc.
