no bug A-10A alt hold mode not engaging

[Coastiejeff]

Haven’t flown the 10A in a while, jumped back in for some fun but it seems the alt and path hold won’t seem to engage for me. Am I forgetting something? I’m doing alt+1 or 2 then A, but nothing. 
 

any suggestions are welcomed. Thanks

Enable the autopilot system first (LASTE) by Lalt + 4. Then do the rest as you described.
To turn the system off press Lalt + 5.

Also, vertical speed must be less than 1 (in the indicator, can't remember if it is x100 or x1000), if not it will not engage.

I don't have the A-10A, but I have the F-15C and I think the same philosphy applies: You need to hold the aircraft precisely in level flight and turn on the Path Hold mode before turning on the Alt Hold mode. That, and it will automatically disengage when you move the stick.

Arm the EAC then use the LASTE.

Hello. 

I'm new to DCS and started flying the A-10A moving from learning to fly using the basic Su-25T. I have a Thrustmaster Warthog HOTAS and T.Flight Rudder Pedals. 

I am not able to get the A-10A Autopilot to work. The AP is bound to both the keyboard default keys - "A" and "1-9 + LAlt" - and the Warthog Throttle switches 26, 27, 28, and M+28 for modes AP Engage/Disengage, AP Path Hold, AP Alt/Heading Hold, and AP Alt/Bank Hold respectively. 

I know that you're supposed to select the AP mode first and then the Engage switch. I've tried this both from the Keyboard and the Throttle, with no luck.

Hello and welcome to DCS.

I believe the answer you're seeking is here:

Yes that was it... EAC (Enhanced Attitude Control) must be armed - in the ARM position on my Warthog Throttle switch 24. The Autopilot settings now work. 

The Warthog Throttle faceplate shows an Autopilot bracket above switch 26 (AP Engage/disengage) and switch 27/28 (AP Path, Alt/HDG, Alt), nothing indicating switch 24 is needed too.

The first time I've seen this explained. I had thought EAC was somehow related to ECM (Electronic Counter Measures). 

Thanks.

You're welcome.

@cfrag had some excellent A-10A training missions...

Yes CFrag made some excellent A-10A training missions. I found them a few weeks ago and they're the reason I moved from the Su-25T as my basic training aircraft to the A-10A. Thanks.

I'm having the same issues. EAC is armed, buttons bound, but no autopilot regardless if I use the keyboard or bindings. No HUD annunciation, nada. I tried it in level flight, VV centered, still nothing.

Suggestions?

So, it seems in the kneeboard lua fix (change the lua file to declare_kneeboard_Device2 to make the kneeboard the size and position you want) there is an obscure line in the Eagle Dynamics\DCS World OpenBeta\Mods\aircraft\Flaming Cliffs\Cockpit/A10A/device_init.lua file, where it declares kneeboard_device_left vice the above.  Just above this entry is creators = {{"A10A::avAutoPilotInterface_A10A"}}. Once I got this figured out, the AP now works as advertized, AND the kneeboard renders properly where I want it (bottom right corner). The final file should look like this if you are using the kneeboard size fix:

attributes = {
    "support_for_cws",
}
creators = {
{"A10A::avAutoPilotInterface_A10A"}
}
---------------------------------------------
dofile(LockOn_Options.common_script_path.."KNEEBOARD/declare_kneeboard_device2.lua")
---------------------------------------------

this caused my plane to disappear.

Wow, mine was fine. Do you use the "kneeboard fix" thing?

Thank you!!  I've been looking for this!
