CWS and OAT

Camo

@Buzz I can be climbing with AP/YD/NAV/IAS mode selected and an altitude set. With the SIMCONNECT binding I get no CWS message and the AP does not release pitch control. I push the nose down to increase the IAS but it just reverts to the previous attitude/IAS.

I also tried it by pressing the actual CWS on the Sim yoke - the CWS message appears but control/AP response is the same. Happens with either the G530 or PMS GTN 750 installed.

@Camo The pitch sync adjusts only the pitch axis, not the IAS reference.

Try this..

Load the 850 on to the runway threshold ready for takeoff.
Align heading bug with runway heading.
Press the TO/GA button.
Make sure FD is visible on the AI..The FD should be commanding about 5-10 degrees nose up and wings level.
Takeoff and handfly the aircraft to 500 feet on runway heading.
at 500 feet engage the autopilot.
The aircraft should be in a stable climb.
Press and hold the pitch sync button and push the yoke over to command a lower pitch.
let go of the pitch sync button.
The plane should hold the new attitude you just set..

Hi @Buzz - In essence, that was what I was doing in the explanation above - change in pitch changes IAS. The TO/GA function works fine (as you indicated).
I get no CWS message in the AI so the CWS function is not active.

When I press the CWS button on the Sim yoke, I get the CWS message but when I push my hardware yoke forward, the FD bars do not follow and settle at the new pitch commanded with the yoke - it just pitches back up to the original commanded FD pitch angle. It appears that the AP is not releasing the servos to allow the pitch change.

I have tried a different hardware button (and no other buttons are mapped to SYNC_FLIGHT_DIRECTOR_PITCH.

@Buzz - Ahhhhhhh. I finally see the light. I had IAS mode selected on the AP panel and it doesn't work in this mode (as you suggested but I didn't get :) ). I guess I thought it should work in that mode as it does on the BAE146.

It works now but still don't get the CWS message in the display (as you do when you select it on the actual Sim yoke). I'll raise a Ticket with JF.

Mate, thanks heaps for you help - old blokes are sometimes a bit slow on the up-take.

As of this moment, there is no way for a developer to detect if the pitch has been resynchronized without intercepting input events, which raises its own can of worms that I try to avoid whenever possible. I'm glad the functionality is working for you now, though!

@Black-Square Thanks for the response re IAS and CWS. Will you be able to get the CWS message up on the AH when the CWS button is held-in?

Black Square

That's the part my message was in reference to. I can't display the CWS indicator on the screen if there is no variable I can use to detect it.

Camo

@Black-Square - Ahh got it. How about the IAS/CWS mode working? Thanks heaps.

I understand that the CWS indicator can't be displayed via the MSFS native command because there is no variable to detect it.

However if I assign one of my hardware button to the sim yoke button, with an external software like FSUIPC or AAO, will I have the CWS display on and the CWS work too?

I'm using only MSFS native commands now so this is just a pure inquiry out of curiosity.

Buzz

Right on @Camo. I'm just glad you got it sorted out.

Cheers
