I have FSX with accelerator pack, Radar Contact 4, Active Sky Advanced, and Its Your Plane Running while flying a Beechcraft Duke. ATC is giving Altimeter checks every 3-5 minutes while enroute. It's bad enough that they are so frequent but they change quite a bit. As a result the autopilot is constantly readjusting altitude and ATC is on my case for not maintaining proper altitude. Anyone know how to correct this? I know from flying real aircraft that Altimeter checks never come in every 3-5 minutes (unless the pilot is crazy enough to ask for them). Also, I have rarely seen settings change so drastically over such a short time period for a travel distance of less than 20 miles.

Hi,Is DWC On or Off in ASA?

The altimeter settings are extremely important below 18,000 as you must fly to a certain altitude and, if your altimeter is wrong, ATC will be telling you that you are above or below your assigned altitude. Above 18,000 and the altimeter setting is always 2992. But, if you don't change it to 2992 after 18,000, ATC will tell you again and again you are at the wrong altitude. If you're at the wrong altitude, you may end up colliding with a heavy and you don't want to be doing that in January!Best regards,Jim

That is the point I was trying to make with my post. The altimeter settings are changing so often and so drastically that I cannot maintain the proper altitude. After logging about 3000 hours flying multi's in the USAF and SEL as a civilian my "flying" these days is restricted to flight sims and I really want realism. These altimeter settings are just NOT realistic..both in frequency and pressure change.I have probably set something improperly but don't have a clue as to what it might be. At the moment I don't recall what DWC is in ASA but will check tomorrow. Should it be on? Any help appreciated.

Don't know if you know this but all you do is press the 'B' key (on your keyboard) and it will reset the atomospheric pressure (which is 29.92 JIM, not 2992). If above 18,000 ft you reset it as you climb thru that altitude. When you're descending, your press the 'B' key again when you pass thru 18,000 ft on your way to a lower altitude. That simple. PRESS THE 'B' KEY, PRESS THE 'B' KEY.This also works to put the aircraft you see 'on the ground' when flying online. They will show hovering if you don't press your 'B' key. PRESS THE 'B' KEY ( I love saying that-PRESS THE 'B' KEY, PRESS THE 'B' KEY-try to forget it now (hehe)).Chuck BNapamule

FS weather gives you 'somewhat' realistic weather. FS ATC is 'kinda' like what happens in the real world. these are limitiations in a game that costs <$60 (US)don't expect all that much ... just fly and enjoy.

Both my "B" key and my left index finger are worn out from all these altimeter changes. My RC4 co-piloy has rebelled and will not acknowledge then after the first 20 or so. He is not long for this world unless he shapes up soon.All I REALLY need to know> is there some setting I need to change to decease the ffreqency of altimeter setting reports?

My recommendation: re-read and answer Jim Skorna's question - he can answer ASA questions for you. Then ask this question again in the Radar Contact forum here in Avsim if you are using RC for ATC in this case.

Don't reset the altimeter using that "B" key. Reset using the proper method--turn the knob. This will not solve that frequent altimeter report problem but will eliminate others.

I have the same problem using ASX. Altimeter settings below 18000 ft keep changing everycouple of minutes. Not very realistic.I also use RC4.I brought this up on the HiFi forum, but didn't get any solutions to the problem.I stopped using ASX and now use FSX static weather.Arnold

Hi All,Please be aware that I did answer Seaox on the very same day that he posted and he never responded and that was in November 2009.Now, baro. smoothing is not something that FSX models. With ASX, every weather station gets set with its own pressure and as you move from one station to another the data is going to jump. With ASA running with DWC on, some of this is going to be smoothed out, but it still can happen.The fix is to use registered FSUIPC and use the baro. smoothing option located there.

Hi Jim,Excuse my ignorance- but what is "DWC"?Thanks Bruce.

On a flight made the other day in the Learjet above FL180, the barometric pressure, while enroute, kept changing every few minutes (My altimeter was set to a constant 29.92 but the A/C kept increasing and decreasing altitude). I'm surmising that this altitude fluctuation was caused by the reported change in baro. pressure, which is downloaded into the sim. I understand that, in reality,baro pressure changes to some degree, as you fly along your route, but these frequent changes got to be somewhat annoying.I always use Real Weather w/15 minute updates. My guess is that the problem lies with the wx engine from Jeppesen. I don't know how Jeppensen gets it's data but it seems that the baro pressure changes "too frequently" over relatively short distances, more than what happens in reality. I'm not a RW pilot so I don't know this for certain. But I think this is something that originates with the wx data that is downloaded to our computers.

DWC is "direct Wind control" in Active Sky. In general, if you are using ASA, disable DWC as its' being enabled seems to lead to a variety of problems.I have been using HiFi Simulations products since AS6.5 (including ASX and now ASA) and have never had the problems with too frequent baro pressure changes being required. I usually seem to only get baro read outs when I request them or as I am passed off from center to center. Sounds to me like there is some other culprit at work here than either Active Sky or Radar Contact (I run it too).

Thanks for all the thoughtful responses.I'm slowly learning how all these add ons may interact . DWC was already turned off so today I tried it on and got what seems a proper number of altimeter checks. I also registered FSUIPC but haven't tried FSX since doing so.This sim with a few good ad-ons really does put the "feel" of real flying back, especially during an ILS approach on a rainy night. Now if they could only work in a GCA approach and shut down all those super nav aids.......
