[SOLVED] Flight director not working correctly

[mosquito3]

Hallo

I've bought the CRJ just 2 days ago. Amazing addon...never seen something like this before in X-Plane

But....i'm having some trouble with the flight director. For example flying manually an ILS with flight director engaged, approach armed, the bars do not give the right indication to follow the glide and the localizer. Also in every vertical modes, when flying the plane manually, the flight director doesn't lead you to the desired vertical speed, or at the altitude hold, ecc. Another example: i'm flying north, i engage HDG and set the heading bug to 090. The vertical bar of the flight director never center when i reach 25 or 30 degrees of bank during the turn but remains all the way on the right. Never seen a flight director working that way. The problem is just mine or the FD is just not working correctly for every one else?

Hope my english has been at least understandable

Thanks in advance. Best regards

strange.. hope Philipp can reply.. because what it do when autopilot is follow the FD and it always follows correctly.

1. are you able to make the plane follow FD in automatic mode?

2. did you connect Yaw dampers?

3. did you tunned correctly the radios?

4. did you put source nav on correct mode?

cheers,

Hallo Japo and thanks for your reply

1. For example. I'm following the fms route with autopilot ON and flight director ON, Nav mode and alt hold engaged. Now the plane has to start a 90 degrees turn to the left to follow the route. Ok the vertical FD bar start to move to the left but when the plane reaches 25 degrees of bank the bar never centers and remain all the way to the left (center only when the plane reaches the target heading). Also with AP engaged the orizontal bar (vertical modes) sometimes do not center.

2. Yes

3. Yes

4. Yes

I'll make some test today and will take some screenshots to explain better the problem

Thanks again.

if stays in 25º is because you put maybe 1/2 bank mode. When starts to turn to the left the FD should stay on the left.. when near the desired heading angle, the vertical bar should go to the center or right to make the plane fly that direction (if not it won't never catch that direction), maybe is not big sensitive for you?.. don't know.. just asking. This type if things better on video if possible.

So my question is.. The plane finally is going where you want it to go? if so then FD must be right because the plane follow FD. Other thing is maybe is too much sensitive, or too much steppy in animation....

I don't want to be nagging but that's not the way a flight director should work.

A flight director should lead you to perform a manouver correctly.

Just another example: I'm flying heading 360 and want to reach heading 090. I set heading 090 than the flight director vertical bar SHOULD start to move to the right and CENTER when the standard angle of bank is reached (i believe 30 degrees normally and 15 when selecting 1/2 bank). Then the vertical bar SHOULD start to move to the left when near 090 (that mean that you have to level the wings to stop your heading on 090) and CENTER when my heading match the heading bug (090) and the wings are levelled.

A flight director should work just as above.

In the CRJ the vertical bar go in the center only when the selected heading is reached.

Sorry i can't explain better. The flight director is reproduced pretty well in the default X-plane AP so you could try to fly the same situation with the CRJ and with a default aircraft to notice the differences.

Anyway i'll try to record a video later.

Thanks again, best regards

ok.. now I understand.. Lets wait philipp what has to say. I just emailed this morning about this issue.

cheers,

Ok, thank you Japo for you fast reply

I confirm there is an error with the order of the transformations applied to the flight director.

Fixed for 1.1 version.

good!.. The good thing about this, it is that proove the autopilot is not the default one as someone said.

[mosquito3]

Good 8)

Nice to know that the bug is confirmed and will be fixed in the upcoming patch.

Thank both....expecially Japo for his patience

No problem, my fault not seeing this one when testing.
