Fly heading 232 for 35, qfe 29.............

Ah, I see. That still has nothing to do with millibars :D Unless it's an assumption I'm not aware of!

 

But yeah.

So how do you set the altimeter? I must have missed that part of the manual (unless I'm not there yet, but I'm true the first section on instruments). If anyone has a page number that'd be good enough for me. :)

There's a dial at the bottom left of the altimeter. Mouse over it and scroll up/down to change the pressure setting.

Well, being a guy that only flies stateside, I, for some reason, always thought the QNH call was for the millibars... but even still, instead of QNH it should be "Altimeter".

 

It shouldn't be "altimeter" nor should it be "QNH". It should be QFE, just like real world operations over there. :)

 

 

Even still, assuming 29 in place of 30 doesn't seem to give you proper QFE. I was wondering if maybe adding/subtracting QNE would give you a correct reading. Don't know. Fingers are crossed for 1.1.0.8 though!

And the pressure setting is displayed in the numbers on the bottom right of the altimeter?

 

If I understand correctly, this essentially then sets the proper ground altitude for the airstrip?

Yeah, the four digits in the altimeter are the altimeter setting. The setting the ATC gives you is currently broken, but that is how you set the altimeter.

 

There are a couple different ways to set it.

 

There's QFE (field elevation), which is what the ATC will give you. This is basically setting the altimeter to 0 on the runway

There's QNH, which is elevation above sea level of the runway. This is setting your altimeter to the runway's elevation (above sea level)

QNE is a standard elevation - "pressure elevation" - 29.92. This won't necessarily give you an exact reference to the ground, but it's useful when you're trying to maintain separation from other aircraft or other such things.

 

Wikipedia has some more on the subject.

There are no USAF operations out of airports in Russia so there's no "real world" to compare it to. In real life A-10s would fly out of Incirlik AB, Turkey. In Georgia (where most of DCS flight takes place) QNH is the standard for civilian and military aircraft. In the fantasy scenario where USAF A-10s are flying out of local airports, controllers are going to be USAF personnel and use USAF procedures, meaning QNH.

 

The only example of USAF using QFE is operating out of RAF bases. I don't know if they still do that any more.

 

Even if for some perverse reason QFE was used, it would only be valid in the terminal environment. More ATC would be needed to provide QNH outside of the airport proximity and definitely before conducting any CAS. Since DCS does not attempt any such ATC, ATIS, or AWAC functionality and the A-10 avionics are heavily biased toward the use of QNH, QFE (or rather QFE alone) is not an option.

 

Even still, assuming 29 in place of 30 doesn't seem to give you proper QFE. I was wondering if maybe adding/subtracting QNE would give you a correct reading. Don't know. Fingers are crossed for 1.1.0.8 though!

 

QFE given by DCS ATC always gives you an altimeter indication of 7,780' on the airport surface. I don't know why but no matter the air pressure or field elevation, it's always 7,780'. The ATC reported QFE and the actual QFE differ by approximately 10" Hg (between 9" and 11") which makes the "subtract one" thing only very, very grossly applicable.

Nor was I saying there were USAF operations out of Russia, but airplanes do fly in Russia, and when they do, ATC gives them the altimeter calibration setting in QFE, unless at QNE altitude. :)

 

Altimeter setting isn't a preference of the Air Force, it's a mandatory flight rule. The "real world" example you can compare this to, is by looking at the Russian Federation flight rules, which the USAF would adhere to.

You know what's also normal procedure? The entire Russian ATC system. Where is it? Where's approach, departure, center? Where's IFR at all? Not in DCS. Russian aviation is almost exclusively IFR in real life. In DCS it's missing.

 

Sure it is very happy to send out A-10s with Nalchik QFE setting to go bomb a target? What? How does that work exactly? Please describe to me how that works. Your last clearance was 300m height on take off. ATC doesn't say a word after that. What do you do?

Bumping this thread since the new patch dropped...

 

I haven't had any time to fly or install the patch...but is this one fixed now? :D Specifically the correct numbers that were way off in the last patch...
