upper winds fixed in sp2?

Recommended Posts

It may be that disruptive transitions are not a universal artifact in ASX.I just completed a flight from Tampa to KNEW without much variations in wind at FL310 while asc and descending, and in level flight. It varied slightly along the path but never once did I notice any abrupt twisting like before in a different flight.So things may be OK after all,I add that the flight was a dream, with not a single instance of bizarre visibility extremes, everything went wuite smooth with only some stepping through the diff vis. I was not bored throughout the flight, whereas before, I'd get annoyed when all of a sudden I had unlimited vis then haze, then unlimited...allen

Agreed Peppy, they don't happen everywhere. I've now done 5 decent flights with SP2 and some of them have been completely uneventful "upstairs". So far I've done: EGPF-EGSS (LDS 767X) - nasty wind shifts and wind reversal on finalEGPF-EGGW (Wilco A319) - smooth as silk cruise, QNH a country mile wrong on approach (1006mb v 987mb)ENGM-EGPF - (Wilco A320) Nice cruise, one or two wind shifts but not violent. Winds were completely wrong at destination, 275 degrees when should have been 050 degreesBIKF-EGBB - (LDS 767X) Suspicous CTD climbing through FL270, my first ever CTD with FSX. Restarted and cruise absolutely fine, a few subtle shifts, nothing nasty. Approach winds fine.LOWI-EGSS - (Wilco A320) 100% the whole way barring the QNH on arrival being 5mb too high

Hi All,Thanks so much for the continued feedback, positive and not so positive. It does look like many times things are working as designed, but other times there are wild shifts. Everyone knows that we are still on this!Thanks again,Jimhttp://www.hifisim.com/banners/hifi-community-sigbanner.jpghttp://www.hifisim.com/

On a more positive note Jim - the cloud depiction is now nothing less than stunning! The graduations climbing up through the layers is now awesome, fingers crossed on getting both wind and pressure smoothing to match!

Hello all,KLAX-NZAA in a PMDG 744.Beautifully smooth on the way up and at cruise however descent and landing were a different story with IAS yo-yoing between 320kts and 195kts in a matter of seconds. Winds on approach were a nightmare.I know there ahs been a huge amount of effort put into SP2 but unfortunately things do not seem to have improved for me in the one area I was hoping :( However, I will keep trying flights to see if there are any determining factors.Out of interest, are the developers seeing these issues when they run ASX or is it only something that certain people started reporting when ASX was released?Dan.

I havent had most of the probs seen in this forum and I'm running an older single core.

>I wonder if its CPU core related. I havent had most of the>probs seen in this forum and I'm running an older single>core.>I am running a single core and I have gotten violent wind shifts on every upper level flight (which is only two flights...) I've done so far with SP2.Perhaps it is region specific in terms of not many stations? I am flying in the Middle East right now. Perhaps I need to uncheck Virtual Stations and just let the actual stations govern what gets into the sim?Here's my SP2 flight list and what happened:OMDB --> OKBK (default A321) great up until last part of the cruise; then violent wind shifts over the northern persian gulf. Cruised at FL34OKBK --> OIII (SGA DC-10-30F) wind shifts within 1 minute after takeoff from Kuwait City; then the rest of the flight all excellent! ?? Cruised at FL31OIII --> OERK (default A321) good first part of flight; then over northern persian gulf, n saudi arabia, wind shifts at cruise altitude. Cruised at FL36OERK --> OEJB (Eaglesoft Twin Comanche) great flight all around, no wind shifts at all. Cruised at 9000 feet.Sometimes I notice gradual shifting, which is good, and I can see the program incrementing speed and direction. But other times it seems like the data it's getting it doesn't know how to handle.Maybe I need to try a flight in the US, where there are more reporting stations (hence a finer grain of data).RhettAMD 3700+ (@2585 mhz), eVGA 7800GT 256 (Guru3D 93.71), ASUS A8N-E, PC Power 510 SLI, 2gb Corsair XMS 3-3-3-8 (1T), WD 150 gig 10000rpm Raptor, WD 250gig 7200rpm SATA2, Seagate 120gb 5400 rpm external HD, CoolerMaster Praetorian

I see your setup is closer to mine then I've seen on here. Im running all this on a 2400+ XP 2ghz. 2Gb Kingston PC2100, Geoforce 7600 GS OC'd to 504 Mhz 512MB. Asus A7V8X-X. 7 Drives too many to list (grin).Anyhow I do alot of flying along the eastern seaboard and so far has seemed pretty stable. I have an unattended Level-D flight going on right now just to see what happens from KEWR-ESSA as I flew this IRL 8 years ago when I moved here. When I woke up so far so good.Had an interesting flight 2 days ago in a Mooney Bravo from PAPB-PADU. 0 visibilty in snow w/40mph gusts. Was getting kicked around from left to right the whole way but the gusts and kicks were very very smooth compared to SP 1.

Forgot to mention I dont run enhanced route or virtual stations either but I do have wind smoothing, Vis grad and foglayer enabled. Also Skyscape and skyscape

Hi all,Installed SP2 and I experienced wind shifts "as usual" with Virtual Station option set to on.Once switched it off situation has greatly improved! Not shifts on Cruise FL but only few ones on my descending path...One more question: should SP2 have fixed the so called "Overcast Issue"?I still believe my ASX's weather deciption on bad weather situations is not as real as ... it should be...ThanksNick

I am aware of all of those threads, in fact I am probably in some of them :) I am saying, that on my system, I am getting convincing overcasts using FEX and ASX set to 7 cloud layers max.I think part of the OVC issues people see are:1) overexpectations as to what FSX can physically do2) bad settingsRhettAMD 3700+ (@2585 mhz), eVGA 7800GT 256 (Guru3D 93.71), ASUS A8N-E, PC Power 510 SLI, 2gb Corsair XMS 3-3-3-8 (1T), WD 150 gig 10000rpm Raptor, WD 250gig 7200rpm SATA2, Seagate 120gb 5400 rpm external HD, CoolerMaster Praetorian

Hi,two things...1) what program made that map?2) for HiFi: what is the source of upper wind data? Unisys? Accuweather? I ask because I'd like to know how you are determining upper air wind speeds for overwater portions of a flight like Karl is describing. What what is described above, there are no upper-air updates overwater and the last land-based station report is used until the aircraft is in proximity to a new land-based station. Is this correct?Thanks,Jeff

Thanks for the reply.Are these sources a trade secret? Do they cost money? Do you know of any free sources of upper air data?Thanks,Jeff

I am getting some very bad wind shifting at altitude during the cruise as well.. Throwing the PMDG 747X around all over the place... I'm even getting into overspeed and near stall.. This cannot be right..I've got SP2 installed in ASX.. Perhaps someone could tell me what settings to use so I can get rid of this problem for the time being while it's looked into?CheersCraig

And another thing, how come when I click disable winds aloft.. and FSUIPC is off.. and the MSFS weather control says there are no winds.. I still have winds aloft!CheersCraig

Hi Jim,I actually found that one since posting. I just wish they provided the data as one big download... I'd like to put the data in a spreadsheet for flight planning. Your brief feature is nice, but it lacks a total average groundspeed for the entire length of the route. I need this groundspeed to calculate fuel burn.Thanks for the tip.Jeff

Just to add my comment, i know you are working on it Jim.Sometimes I get Turbulence while on the ground no other aircraft around, shakes me up pretty good.More often than not while in cruise my air speed drops drastically or the plane speeds up to disintegration. Cross winds so severe it makes it difficult to stay on track.When I enter a station at the main ASX screen, I do this to check departure and landing runway choices, I get an unrealistic wind reading due (according to the notes) wind smoothing? Makes it very difficult to use the ASX interface for weather planning purposes. Case in point departing CYQG actual wind 110 07kts, ASX says 210 08kts. The difference between departing rwy07 (which it should be as it is the active) or rwy 25. Also noticed that switching from "download" weather and Vatsim weather made no change in my example, (doesn't mean anything just a statement). I usually use Environment Canada for weather planning and it is rare that Vatsim weather is as updated.Graphics are gorgeous and I have been with Activesky since it was free, love the product look forward to the repairs.Vista 32QX6700 Quad 2.66 @ 2.94XFX GTX 8800 PCIEStriker Extreme MBHDD Seagate 400GB 2x Raid 0RAM 4GB 800MHZ PC2-6400CH YokeCH PedalsGoFlight GF45, GF-MCP, GFp8, GF-TQ6, GF-LGT, GF T8UTX CanadaScenery TechFSGenesisFS scene all seasons North AmericaPMDG 400X FSX Deluxe with SDK and SP2ASX SP2ASX Graphics SP2FSUIPC registered weather off.FSINN 1.3 Weather off.
