Wind Shifts

[brodie4598]

As we all know FSX is prone to horribly unrealistic and violent wind shifts at cruise altitude(and everywhere else). From out of the NW at 80 kts to
out of the SE at 100+ kts instantly then back and forth every few seconds. Many times you're luckily if the plane doesn't stall. I got to thinking,
what if this happened while using FSP? Is there something built in to ignore these wind shifts so that your passengers aren't all bounced from one
side of the plane to the other. I cant imagine that would fare too well for your rating.

I belive there is a program to download and works with FSX to stop these annoying changes

I had no times to look at this and didn't find any reliable page on this from my fast check
yet but some value in fsx.cfg could maybe solve this issue ?

In particular in the weather section:

MinGustTime=10
MaxGustTime=500
MinGustRampSpeed=1
MaxGustRampSpeed=200
MinVarTime=5
MaxVarTime=50
MinVarRampSpeed=10
MaxVarRampSpeed=75

Maybe everyone overlooked those simple value to smooth wind change without using something external ?
I think it worth a look & test.

Wouldn't FSUPIC and/or Active SkyX solve this issue in FSX?

[DanSteph]

Yes but fsuipc at least is payware for wind smoothing... not that I don't want to advertise Peter's excellent program but I would have
preffered a simpler solution for peoples that might have VNE exceed in FsP... I had it only one time, I was flying near VNE wich is an error
in commercial flight, usualy peoples should not fly just above VNE. Now I keep a safety margin of 30kts and never had it again.

I'm suprised it seem no one did extensive test on those values, the "wind bug" exist since fs2002 at least.
I changed some value in my cfg, I'll see if it make changes.

the problem is that these aren't "gusts." At least I dont think it is. I have active sky and it helps, but unfortunately it doesn't completely get rid
of the problem. In the real world upper level winds are very vfast, but change very gradually so it's not noticed. But these shifts are instantaneous
and cause havoc with the plane (for me it's impossible to fly with crashes ON because the plane would break apart at cruises from these wind shifts).

I guess I'd just be pretty frustrated to get poor ratings on my FSP flights due to an FS bug. Im sure one of the beta testers have experienced this?

Brodie, this is a problem that has plagued both FS9 and FSX. Certainly in FS9 I have cured the problem with the registered version of
FSUIPC and will do the same when I decide to spend more time with FSX instead of FS9.

@Dan..I'll be interested in knowing your results of changing those values

[Tracker801]

I cannot help to ask Mr Brodie this question.... were you flying online and behind Joygirl?
In that case it would be wake turbulance...... get to know Joygirl and you'll know what I mean
Stay off the beans for a while Joy

To my knowledge, there aren't any payware programs that can solve this problem as yet, so I would naturally be sceptical of any 'freeware
solutions' that can...?

So I very much doubt whether a simple edit of the FSX.cfg will completely solve it.

Until a freeware solution does come to light that will completely eliminate this problem, maybe it would be best if a workaround solution could be incorporated into FS Passengers X in the meantime, i.e. maybe to give people the option of whether or not they will be penalised for exceeding VNE, or whatever the penalty is.

I love flying in real weather I've got some odd winds changes but ran only one time in "VNE" because I was near it..
I think in anyway that you should always fly VNE-30/-40 in commercial aircrafts. Doing this I never had any penalties.

PS I Didn't had time to check with new value yet. Gust might not solve the problem but the other look intteresting ?

So I very much doubt whether a simple edit of the FSX.cfg will completely solve it.

Life is sometime surprising... nobody ever tought to make a heating shield for orbiter addons
but it took me three line of codes when I tried. http://orbiter.dansteph.com/index.php?disp=dgIV
Was so "simple" that nobody tought about it before.

It's true many peoples tried to understand and tune the fs config since years but.. sometime ?

What is surprising as I wrote above is that this problem seem to exist since Fs2002 at least...

well I figured out the answer...flying DEN-CVG right now and had massive wind shifts...from normal cruise speed to almost breaking the sound barrier
then down to 80kts (stall) all within about 60 seconds.... My passengers hate me pretty bad, I'm sure I will get a severe penalty for my erratic
flying...oh well I guess I wont be saving this flight.

Ohh wait, in typing this my plane just hit 660 kts indicated...thats mach 1.4 almost...pretty good for an MD11

stupid FSX

[harryj79]

I have been flying in FS9 and FSX for a few years now and was well aware of the awful wind changes. However, I have never had an experience as bad as
the one I had today. I was flying at FL370 over the Pacific when my 767 lurched to the right, then to the left, then started overspeeding before two
seconds later going into a stall and plunging to FL290 before the aircraft eventually recovered. All this as a result of wind changes? As real as it
gets? Needless to say my passengers weren't overly amused but neither was I, considering I had spent half an hour setting the flight up and another
hour and a half flying. An afternoon wasted. I continued my flight anyway, but I have to confess I didn't record it in FSP.
I do sometimes wonder whether Microsoft tests Flight Simulator. Surely it should have noticed this horrific problem? I suppose this sums up my
love/hate relationship with FS9 & FSX and Microsoft, and computers in general.

[harryj79]

I have realised that the very violent wind change may be a problem with Active Sky X that is making it worse. This is the first flight I have done
with ASX installed so maybe it's connected.
