AP disconnect logic
-
When or how does AP disconnect on its own? I am still puzzled when I am on the final legs of an approach and the AP disconnects randomly. I try to keep the aircraft well above approach speeds, but it still disconnects. It only happens on approaches that are part of STARs.
-
I have a similar issue: Once the AP is on, whenever I move my mouse it turns off then on etc. If I have to say change my heading bug; once I do that I have to slowly position the mouse until the green AP triangle lights illuminate then I let go of the mouse so it’ll work.
I have checked and my mouse is not mapped to anything autopilot. Also, it only happens with this airplane. All the others (stock, PMDG, BlackBox, etc) work normal.
Strange.Another note… wonder how the UNS-1K is coming. I recall a JustFlight Dec FB post saying a January release. Hopefully soon :-)
Cheers

@big-brown
Thanks. I am surprised that more users don't report this AP anomaly. tc -
@flyforever It does seem rather sensitive and I’ve had problems getting to grips with it myself but the manual lists conditions in which the AP will disconnect.
-
@flyforever well I figured it out. Being that this anomaly was only occurring on the 146 I knew the answer had to be close. So I tore through all of the control sections and it ended up that my mouse was mapped to “afterburner.” So whenever I moved my mouse with the autopilot engaged, it was actually activating the SYNC feature of the AP. After deleting the mouse afterburner assignment it works perfect. Nine months of agony and now I can really enjoy this bird. But being that I’m a real world cargo “freight dog” it’ll have to wait… starting a long trip tonight. First stop ANC.

@big-brown Gald you got it fixed. I’m having a nightmare with changing altitude with autopilot. It’s just not sinking in!

My method is to
- disconnect ALT if in level flight
- increase or decrease Altitude and then activate ALT SEL
- use PITCH toggle to lower or increase VS
- Once desired VS is obtained, quickly press the VS button to maintain VS.
I've learned that the PItch toggle does not work is the ALT light is on. ALT must be disabled first in order to change altitude.

@flyforever Thanks, yes I realised last night (when I had only six hairs left) that there was a 'clutch' system to quickly disengage the AP then make changes to altitude then re-engage it. I'd been totally disconnecting the AP, changing altitude then switching it all on again. Sheesh. :/
All sorted now I think. Now just absorbing the differences between IAS mode and VS mode.
...once I get the hang of the Airspeed / Mach Speed Indicator Hideously Flexible Ever Changing Complicated thingy with adjustable bugs to set to 'something' which is... daunting.
I'll get there but at the moment it's like pulling teeth. :)

I use the IAS soon after the gear retracts and I establish a climb speed, at which time the IAS button will hold the airspeed by adjusting the VS rate of climb. So in order to climb at a specific VS, sometimes the throttles need to be pulled back. If not, you can find the aircraft climbing at an excessive rate of climb. Similarly, the VS will hold the rate of climb or descent once established with the pitch toggle switch next to the AP switch on the console. In sum, I use IAS only after takeoff in order to establish correct climb speed, and the VS when I descend and want to stick to a specific rate of descent.
