Solved Can't engage Autopilot
-
I’ve tested this on the Navigation TE, Landing TE, and both F-16 packages in the AAR TE. I can flip the ROLL toggle switch fine, but I can’t move the PITCH toggle, or if I can, it’ll come up with a FLCS fail.
I’m not sure if I’m doing something wrong and that’s why the PITCH won’t engage or if I have a switch set up wrong in my physical cockpit that is messing with the AP so much that the PITCH won’t engage. Please let me know what I’m missing here?
Thanks!

On the Manual Trim Panel, Check the “Trim/AP Disc” switch is in the Norm position. When it is in Disc position, the auto pilot will not engage.

Is the fuel door open?

In this U4 version, the autopilot logic is triggered if, while it is connected, the stick is pulled above a certain force that exceeds the joint command threshold.
Apart from other physical variables such as switches, fuel doors and others, they limit the connection of the autopilot, a very important one that is always hidden is the MPO that is hidden when the throttle is advanced in the flight regime. In this case the switch is controlled with the O key, check that it is normal.
In a few hours I’ll take a look at that TE.

@CriticalMass @VIPER-0
Problem solved. PICNIC.
Thanks for your help!
I knew it was not the fuel door as I would notice the indexer light.
Definitely wasn’t the control input or aircraft attitude as I was trying to engage AP without control input and at level flight.@Abe
Thanks! The switch was in the “correct” position, but I’ve wired it the wrong way 'round. Fixed now! -

Wait what ??? What are you talking about ??
There should be no change in the AP logic in U4 and should there be a change that is a bug then
Could you precise how you trigger the bug you describe ?

When I connect the AP in any vertical mode, aptitude or altitude hold and pull, the stick disconnects from the AP and the FCS failure alarm goes off and if the FCS is not reset it cannot be reconnected.
I don’t know if this happens with a joystick but I fly with the keyboard.
As soon as I get home I’ll post a photo and more examples.

Are you talking about F15 or F16 because I’m lost here
The AP disconnects when reached max bank angle or pitch. it’s been like this since day 1 of real FLCS modeling

F-16
I know that it is disconnected by pulling the stick and other flight regimes.
What I mean is that it is in the U4 is that apart from the fact that it disconnects when I pull the stick, it causes an FCS error in the PFL and the AP cannot be connected until it is reset in the FCS
-
MAV is simple.
IN FLIGHT
CONNECT THE AP (ATTITUDE HOLD OR ALTITUDE HOLD)
PULL THE STICKresult
THE AP IS DISCONNECTED
FCS FAULT ALARM GOES ON IN THE PFL
THE AP DOES NOT CONNECT UNTIL FCS IS RESET -
@VIPER-0
I wonder if it is a keyboard issue?
I flew the AAR TE, engaged, AP, then pulled into vertical. No FLCS issues or faults in the PFL. -

@VIPER-0

I flew the AAR TE, engaged, AP, then pulled into vertical. No FLCS issues or faults in the PFL.It has to be something related to keyboard controls.
I realized that no one reported it and MAV’s reaction saying you are talking crazy.so that has to be the stick with the keyboard.
As soon as I get home I’ll try it again, but if it happens, it happens.

There is a video, it is completely HIDDEN, only we here can see it.
First step, connect the AP, pull hard, FCS FAULT lights on in the PFL, reset the FCS and the AP can be connected.
When the afterburner is on and the FCS fails and I try to connect the AP, the aircraft decelerates, which is seen in the head camera as the pilot moves facing the ICP.
FCS FAULT is triggered below 500 knots

Yes I remember leech make me do this fix for U4
@Leech do you confirm ?
-
@Mav-jp Yeah. When the AP disconnects for any reason ( in this case exceeding AOA) you get a FLCS FAULT.
You will need to FLCS RESET,so that the fault clears to re-engage the AP. -

I see no such action

Watch the video when I zoom in on the nozzle position indicator, see how it instantly decreases and recovers, that happens all the time while I intermittently press the A key trying to connect the AP.
Then I try it again with a distant view and since the afterburner is cut off instantly, the pilot goes forward when the afterburner is cut off and backwards when it resumes.

No problems from my end
Is you flight model realism set to accurate ?
Does the same thing happen when you click onto the AP switch with you mouse ? -

Is it normal for FLCS to fail when the stick is pulled?
Is you flight model realism set to accurate ?
yes, correct, flight model in ACCURATE, always
Does the same thing happen when you click onto the AP switch with you mouse ?
The same thing happens with the A key trying and with the mouse.
Leave the afterburner at maximum for about 20 seconds allowing the aircraft to accelerate to +450knots and then touch the A key or click AP switch several times and watch the nozzle position indicator as it tries to drop to zero each time the autopilot tries to engage. -
