I just wanted to see if anyone else has this issue, the setup as follows:

take of from any airport lightly loaded, maintain your speed below 190 knots and hold altitude any will do.  now change heading 90 degrees and watch how autopilot makes a turn, mine for some reason will literly hold the turn almost 3-4 seconds longer then needed thus plane will overshoot correct heading and then start correcting it back and eventually start flying the correct heading.  i tested this multiple times and can replicate any time, even in LNAV mode where there is a sharp turn plane will literly overcorrect or oversteer its course and wouble its way back to correct course.  

anyone sees this?


thanks.

I have the same problem when I fly the 757-300 V2.2

Andreas

i have the same problem with all the variants (-200,-300 and freighter)

giel

Same here.

I bet this has something to do with those parameters in aircraft.cfg:

Quote:

[Custom Autopilot] AP_Roll_speed=3.92 AP_Roll_window=5.5 AP_Roll_controlstep=2850 AP_Roll_mincontrol=-15884 AP_Roll_maxcontrol=15884 AP_Pitch_speed=1.2 AP_Pitch_window=1.8 AP_Pitch_controlstep=41 AP_Pitch_mincontrol=-12200 AP_Pitch_maxcontrol=14200 AP_VS_speed=320 AP_VS_window=930 AP_VS_controlstep=0.9 AP_VS_mincontrol=-15 AP_VS_maxcontrol=30 AP_FLCH_speed=1 AP_FLCH_window=16

i guess this bug was never addressed, since its this way since day one, anyone on fXs can confrim this too?

i guess now it wont be fixed ever.

Same here over steers

additionally I find using lnav it will either turn too early when following a route leaving the plane considerably to one side of the route. When it doesn't turn early over steers.

Was this addressed in the FSX version? Perhaps we can grab values from that release and copy it into the CFG for this version?
