[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

A pilot familiar with that plane is almost certainly going to find it very unstable in the pitch axis, and complain that the nose bounces up and down too much. In the real plane, the dynamic pressure from the relative wind tends to hold the control surfaces in one spot, and it takes a

Major A writes: Is the null zone there in a real aircraft (backlash), or just a feature of the sim to allow the pilot to go and grab a cup of coffee? I think it's a different attempt to compensate for the lack of control loading. -1.0 = -1.00 -0.5 = -0.25 0.0 = 0.00

This is a good response, but it also implies that at 0 deflection, the control is totally nonresponsive (gradient is zero). Shouldn't we simply add a linear term here? That would make the control linear around the centre and transition into a square response at higher deflections.

Major A writes: Yes, but wouldn't it be better to have at least a small amount of control around the centre? You do. Unlike a dead zone, this approach has no location where moving the joystick will not produce some kind of input. All the best, David -- David Megginson, [EMAIL

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
