Can't Change AP pitch

JetNoise

@martyn I'll do some more testing on my side, before i raise hell ;-)

@jetnoise I'm sitting here on the ground playing with it... are you using the GPS unit? I just tried without the GPS unit and with the GPS and it seem like it might be an issue when using the GPS unit. Because when not using the GPS unit I was able to move the pitch trim with the pitch hold reference without it immediately snapping back to whatever. However when the GPS unit was enabled it immediately started snapping to what it was before when using the pitch trim switch/binding.

Melon

@martyn I think it might be to do with the GNS being enabled. Shall submit a bug report though.

JetNoise

@melon great finding. Actuall i had the GPS "installed" but was doing the tutorial VOR/VOR.
I'll check on my next flight ... (later today)

@martyn is that of any interest maybe

@jetnoise Yeah, it definitely seems to be because of the GNS. Just did a flight without it and the pitch controls worked perfectly.

Martyn

@melon Thanks for confirming. We are investigating.

Just a comment, besides INCREASE/DECREASE AP PITCH HOLD control assignments, INC/DEC VERTICAL SPEED can be used as well to control pitch, for those that probably have a controller already mapped to these events.

With the GNS 530 NOT selected, I still have issues with pitch modes.

After takeoff setting AP on and controlling pitch works fine.
Having an altitude selected, makes the AP switch from Pitch to HT, but while it tries to level out, it keeps climbing through the set altitude.

Changing back to Pitch mode, the stabiliser seems to be stuck, and I can no longer change the pitch - the elevator trim wheel simply snaps back.

I have tried to disable the WT GNS 530 in the Panel.cfg file, but with no change.

Edit:
On my Stream Deck I can monitor the in-sim (Asobo) Autopilot settings.

When I engage the F28 AP, then the following in-sim (Asobo) AP functions are set to ON: AP Master & Level mode.
The F28 AP shows Roll & Pitch, and I can set the Pitch with the switch on the Pedestal or by pressing the V/S Inc./Decr. switches on my Stream Deck.

Once the F28 comes close to the Altitude preset, the in-sim AP changes to V/S and the V/S value decrease until it reaches the set altitude, where it changes to ALT hold mode.
But the F28 just keeps climbing and the Elevator trim wheel seems to be stuck, or rather snaps back to it´s initial position when I use either the Pitch switch (or V/S Incr./Decr. switches on my Stream Deck).

I wonder if any 3rd party addon can affect the AP.
I have alot of Aircraft addons, but most uses the standard (now WT) GPS units, PMS 750 or TDS GTNXi.

Edit 2:
I tried to disable all my addon aircraft in the Community folder to rule out any incompatibility with any of those , but to no avail.

Wothan

Just a thought...

Could the PMS GTN750 or TDS GTNxi 750 cause Autopilot issues ?

Also - is the F28 using standard MSFS AP functions, or are some of them custom coded ?
The reason is that when I look on which MSFS AP functions are actve on my Stream Deck, I wonder why the LEVEL mode always seems active.
Also when I use IAS mode, once I get near the Preset altitude, the MSFS AP switches from IAS to V/S mode with decreasing V/S as it comes closer tol the Preset altitude and then goes to ALT mode.
But while the MSFS AP indicates to be in ALT mode and V/S is set to 0 ft/min on my Stream Deck, the Aircraft keeps climbing.

taguilo

@wothan Yes, the autopilot uses custom code in the process of leveling off towards an altitude capture, both in PITCH and IAS modes. This is to smooth the capture form an otherwise different behavior with or without GNS selected. However, once altitude has been reached, the AP is totally controlled by MSFS ALT HOLD mode. It seems in your case there might be some controller mapping issues. We are going to investigate that.

Wothan

@taguilo
Note that I´m not using any controller for the AP other than AP ON/OFF Toggle on my Yoke and the V/S Incr./Decr. on my Stream Deck.
In the start I used the blue Pitch switch on the Pedestal, but with the same issue.

I have only tried the F28 4000, and will try one of the other versions this afternoon.

So I´m pretty sure that this isn´t a controller mapping issue, but rather some backround app intervening - or a F28 bug.

I was in a state today where pitching up would work while I held the switch but as soon as I let go it reverted. I resolved by cycling the AP once. Aside from that it's been working fine for me.

Melon

Was one of the 'manual' fixes this update resolving the pitch snapping issue?

Martyn

@melon The manual updates refer to the documentation. We are still trying to reproduce and identify the cause of the pitch selector issue(s).

Melon

@martyn ah, right that sort of manual... haha.

I'm having some problems with the AP

When I select GPS the autopilot is not able to sustain level flight. For example. When I select FL 280, the autopilot passes that level and I have to play a bit with the yoke so that it can be more or less close to the level of flight that I want. but it's hard to fly like that.
It may be that sometimes I select the type of flap and the V1/Vr for takeoff in the first officer's panel (I'm investigating)
It could possibly be due to a tail strike, sometimes the winds are so strong that I hit the runway gently and this can happen (I'm investigating)

all this could be a coincidence or just my F28 sometimes doesn't like to fly lol

Cedric Hunter

Have the same issue here...

There's a fix or not yet?

Cedric Hunter

Thank you guys ! With the 1.2 there's no more issue with the pitch !
