Special Options: PPR?

[Rhinozherous]

Hello!

No info in the Manual about this special option... what does "PPR. Pedals override heading hold" exactly do?

Thank you

Instead of holding the trim button to make changes on your heading, and relase it to keep the new one, just press on the rudder pedals to change that heading makes turning Heading hold off while you keep pushing the pedals, until you release them.

Thank you very much!

My question would be; is this behaviour that was found in the real helicopter? Or is this a "game-ism" for ease of use? I imagine this is going to be quite a difficult question to answer given the relative obscurity of the helicopter and lack of surviving examples.

 

Yeah, interesting question. I guess it could be similar to the Hind, which has microswitches on the pedals, you can push them in to tell the autopilot you're intending to change heading. Not seeing those visually in the cockpit but I guess it could in theory be a similar system?

Doubt this would work for me though, since I have unsprung pedals, so they're _always_ pushed.

I might be corrrected, but in my discussions with Volk I was told to the best of his knowledge there are no switches in the pedals like Mil helicopters. I think it’s a gameism trying to make the helicopters UI a little similar 

I still think Apache has best way to disable heading hold

Not exactly!!! 

Thanks ED for adding this option for BS3...would of been nice to have also on BS2. But probably not worth doing for BS2 since it will probably get phased out soon.

Makes flying and navigation corrections much easier and less painful. When activating "PPR. Pedals override heading hold" in the special setup of the Ka-50 III, making heading corrections via rudder input allows course changing stabilization to be done without turning off autopilot Heading Hold (AHH). So, Heading Hold is not turned OFF when rudder input is done (not on my installation of DCS OB). Once course is changed via rudder input, gently releasing the rudder stabilizes to the new course and Heading Hold keeps doing its thing.

However, one could say that AHH is overridden by the rudder input without being turned off, soo the statement by @Esac_mirmidon is true.

A very nice user friendly feature indeed. And if you find this does not respect real machine operation, and it bugs you, then just turn it OFF. 

Everest...Out!

Well, when i said Turning Heading Hold OFF i mean the Heading Autopilot Channel is not fighting your pedal inputs anymore, but the Heading Dampers are still doing its job.

Thats how the TRIM button works, when you press the trim, and keep it pressed, the autopilot channels are still on but only in the damper function. What you are disengaging is the authority of those channels to keep the helicopter last trimmed position on those channels. 

So resuming, any press on the rudder pedals is like keeping pressed the trim button, the autopilot channels are disabled in they authority to keep the last trimmed position, but the dampers are still working, and when you release the pressure, the autopilot channels retake the authority to keep the last trimmed attitude.
