I was disappointed that the GTN 750 integration did not provide full modern AP capability as an alternative. Otherwise, why include the 530 or 750?
The real GTN 750/650 do not even have these AP features. They are a sim convenience. Representing GTNs as simply GPS devices, and autopilot devices as seperate, is realistic.
It seems that this aircraft does not (yet) talk via API to thirdparty products. This is why it does not work with GSX or Neofly4 etc.
I hope A2A will fix this asap
they are working actively on (at least with onair and FSe devs for what I know) Comanche Engine not recognized OnAir, or FSEconomy - The A2A Simulations Community
Thanks, I understand. E.g., the GTN 750 cannot add AP to aircraft that don’t have it such as the C170b (I wish it could!). In this case, I hoped the 750 could activate the Stec features, but apparently not. Although the Commanche has great flight modeling, I’m disappointed I have to handfly to desired altitude then activate altitude hold. But I appreciate it’s an aircraft from 1959…
IMO this is the most realistic and most fun GA plane to hand fly in the sim to date. Well worth doing so! Don’t let the AP have all the fun!
You’re right of course. Maybe the Comanche will get the AP out of my head and get me back to stick and rudder flying. Like when I got my high performance certification IRL, I spent ten hours in the Piper Arrow learning to use retractable gear and constant speed prop without ever using an AP. Ah, the good old days…
you can activate the AP, and then set the trim more or less high, it will act close to a VS mode
And mainly for me what makes it fun and realistic is that I can actually trim the dang thing out to fly straight and level 
I might use heading hold if I wanted to punch something into the GPS. That’s usually about it for me.
I did notice something yesterday about my yoke binding, which is the same for all planes. On the right I have a trigger button that is to connect/disconnect the AP. With this what it actually does is cycle though the AP modes. Somewhat useful, and I’m working out how to get a long press of the button to equal a disconnect. It will be tricky because right now if I hold it down it cycles really fast through the modes without stopping.
Oh for sure…I can set power and trim to maintain a proper climb then capture the desired altitude when I get there. Just thought with the 750 integration, I might be able to set VS/IAS to get there. I realize it’s just a different sort of aircraft.
The Comanche itself has some unique things about it that don’t fit well into my set up and that’s made me hold off on purchasing it so far. But admittedly I think I’m just being stubborn and stuck in my ways.
I fly with a Honeycomb Alpha / Bravo set up. The gear switch as opposed to a typical gear lever, the overhead elevator trim as opposed to a typical wheel / electric yoke switch, the manual flap lever, and the autopilot, all have me hesitant to move out of my comfort zone. Not because I’m scared of something new….but because I’m usually so intent on flying planes that match up realistically well with my setup.
I fly 100% in VR, and I’m using the mouse quite a bit to control things anyway…so I guess I’ll just use it a bit more for controlling this plane than I would with most others I fly. I don’t mind using the mouse at all in VR. It doesn’t deter from my experience at all, as I know it does for some people…and if I’m going to fly the plane, I’d rather fly it in all of it’s unique glory, rather than using unrealistic controls that aren’t actually part of the plane.
Sorry for the long windedness. I’m just thinking out loud, trying to combat my stubbornness.
Look at it this way.
The virtual cockpit switches, buttons, and dials can all be abstracted away in the form of simvars, LVAR’s, and so on.
The difference between the VC model, and your cockpit is to a greater degree inconsequential.
The Comanche doesn’t have a Logitech radio panel, yet I can drive the radios just fine.
It also doesn’t have a Logitech switch panel, yet my gear lever works just fine.
The simvars are the abstraction layer that make it all possible.
But since you mention VR later on, yes that makes using physical controls more tricky, doing it by touch, then mouse control or VR controllers is the way to go.
Which reminds me. Instead of those VR controllers you hold, isn’t it about time someone came up with a VR glove, perhaps with single finger that you could wear, and jab at things with that finger. The gubbins could be on the back of the glove, it would know where your hand, and finger tip are at all times, you could hold the yoke, and simply reach out to an invisible cockpit panel.
All the physical controls (flaps, trim, etc.) work fine with the Bravo. I grew up IRL with Pipers, so I’m not put off by the flap lever or overhead trim crank animated in the VR cockpit. I spent a lot of hours in Cherokee 140’s getting my private license and much of that in one that had the overhead trim crank.
Trim it level & you can fly it without touching the yoke anyway, just nudge the throttle for altitude corrections & the rudder can handle anything else. Have flown some distance in it & never tried the AP.
Oh yeah, none of it actually puts me off in a dislike type of way. In fact, the uniqueness is really awesome to me.
It’s just me being stubborn and feeling weird using a gear lever to control a gear switch, or a trim wheel to control a trim crank, or an electric flap control to control a manual flap lever.
So for me, it’s either get over my feeling of doing it this way, and just enjoy the darn plane. OR, use the mouse to control these things, and not my hardware…and again just enjoy the darn plane. 
Mouse or not?
With complex aircraft like the BAE146 I need to use the mouse a lot, just because I don’t have as many switches and axis as would be necessary to handle the overhead panel alone. Still, for standard actions like battery, alternator, beacon, strobes, nav light, taxi and landing lights, cowl flaps, landing flaps, gear, carb heat, and everything that is common to so many aircraft, I want to use my hardware.
I understand, that, as an example, the landing gear switch on the Comanche is different and unique and I’m willing to use the mouse for it (or customize it with Spad, FSUIPC or Axis and Ohs).
Yes, you can trim for a sustained climb attitude with hands off and just add power and a little right rudder during the climb. I flew my C140 across the USA years ago and could trim such that I didn’t need to touch the yoke for fifteen minutes at a time in still air. I could make small altitude corrections in level cruise just by leaning forward or back in my seat.
I’m with you there. Although I really want to use my beloved hardware to its full extent, there are plenty of aircraft where I run out of hardware levers or switches – I don’t resent that at all. I just get peeved when any plane won’t allow me to set ALT, IAS, HDG etc. without a mouse. I was really put off when the Comanche required a mouse to turn on the battery – the first button when you’re cold and dark.
Yes, I agree. This is what has got me back to the sim after a break of around 3 months. I know it’s not perfect (nothing is) but to me this is the first GA I have flown in the sim since it launched that actually feals as if I’m flying a real AC.
Not wishing to denigrate the devs of many other fine GA in the sim here but despite a few hiccups here and there (yes, there are a few) I think it is the best GA so far.
If you use MobiFlight you can assign long / short bindings
