Disabling Flight Director

Postby tfreriks » Sat Apr 13, 2019 1:13 pm

Especially in the Citation II, the Flight Director checkbox comes on automatically and I can't turn it off until I get above 1500'. Then, again, it engages when I get below maybe 500'. Both conditions really screw up my flight plan. Can I disconnect the Flight Director, or stop it from engaging by default? Route Manager works fine without FD.

That makes no sense, a flight director is just a set of bars which would guide you along the A/P commands. It has nothing to do with the route manager or flight plan.

The AP is fine above 1500', but with the Citation II, the FlightDirector box is checked and I can't uncheck it. I set up on a heading or the RM GPS course and a climb in the AP, but when I uncheck the FD, the flight goes whacky. On approach, I have APP engaged (HSI and GS) but at about 1000' or so the FD box re-engages and wants to do whatever it wants, which is usually plow into the buildings. In all the other planes, I can disengage it before takeoff.

That sounds like a generic autopilot controller. :(
Is this the default FGAddon one? Perhaps I'll look and see if I can see the issue.

I don't know what AP it is. I'd appreciate it. The Citation II is my favorite long-distance aircraft, and it's disconcerting to crash on final approach every time.

The AP on the Citation II can not land the aircraft, therefor it disengage it self below 500 AGL (radar altimeter).
This means, you must fly the short final and touch down manually.

PS: i see now what you mean. This checkbox is wrong wired up. The checkbox is checked if the FD is OFF (annunciator light on the panel) and vice versa.
Will try to turn arround it.
Thanks to point it out.

Are you sure the flight director trips off too? That is rather odd, on most planes with no auto land. A/P trips, but FD continues LOC and G/S guidance.

I have only improved that aircraft, not build.
The FD activate/deactivate all modes off AP.
On the Citation II, the FD is linked with the AP. If you deactivate FD, it will also deactivate AP and vice versa.
The AP can bring you down to DH, but not land. So its unnecessary if the FD show you the right controls. Otherwise it can also land.

@ tfreriks
The AP will now disengage at DH set on radar altimeter (but dont set it to 0).
Pushed update to trunk.
Please check behavior.

Hi,
Not quite true, LOC and G/S guidance is not auto land guidance. There is no technical reason that it couldn't guide you, and obviously you deviate when close enough to flare and align yourself.

But yes FD killing AP sounds okay.

Kind Regards,
Josh
