[Flightgear-devel] [BUG] fgfs core-dumps with --airport=kemt

2003-03-28 Thread Melchior FRANZ
Just out of curiosity I've recently tried to request a few invalid airports and noticed that lower case IDs crash fgfs. The reason is the following: runways.cxx:314 searches for the "kemt" airport (320) and "kemt" is indeed found, despite the lower case letters. But then the loop (329) compares the

Ron, I must admid it, you have made my day. :-) Erik Very few MSFS AC have 'realistic' flight models. ;) Though AVSIM reviewers and a bunch of desktop pilots often think they are. FS2K+ can't use realistic values of Cm_q and Cn_r at Mach 0.7/30,000 ft or higher I've had to increase th
