Been using Skyvector and FS Global Real Weather to monitor IRMA while flying folks out of harm's way. Been experiencing some pretty intense weather, depending on which airport I fly out of!  My wishes are with the millions of folks being effected by this massive storm.

Was sitting parked at KEYW and after a about 3 hours my plane had been pushed about 20 feet with the parking brake on. Peak winds were gusting to 32 knots when I started and were at 46 knots when I stopped.

I often have wondered how Real Weather simulates these storms, ie. does it model the turbulence and wind directions, as well as the cloud density and coverage.

Does the video I linked above give you any indication? Using ActiveSky, mind you.

Just watched it--you got bounced around quite a bit there and the Airspeed was jumping up and down quite a bit.  Tough flight!

Yeah, that was not fun. Crazy to think it took only just a matter of seconds to go from me calmly explaining the situation to me full on yelling whilst simultaneously pushing the thrust levers all the way up.

i love flying in bad weather so i've been cruising aroudn the caribeean a lot lately. the activesky hurricane modeling is really cool. it's fun to fly through the eye. i've been doing passes in the p-8 pmdg variant, it would be cool if there was a high end p-3 payware for what the NOAA guys use. 

i notice on the p-3 videos that both pilots have hands on the yoke and there's a 3rd pilot just riding the throttles, it seems like it requires a lot of constant input changes. i read that they do runs at different altitudes like 5,000, 10,000 feet stuff like that but i ahven't really seen a detailed description of how they normally fly one.

in activesky when you enter the eye it's great how you get the circular walls and calm conditions, really neat! i know other people are doing it too, on their PIREPS map there's usually quite a few reports tracking eye position and flights in the vicinity.

good luck to everybody in the path of this storm and those affected by harvey

Amazing how the weather can be modeled so accurately as to replicate passing into the eye of the storm.  I usually configure my weather manually since I like clear sky VFR flight over my photoreal scenery in P3d.  Sometimes I will add a layer of cumulus just to watch the clouds and their shadows on the landscape, which really adds a new dimension to flying that was not there in FSX with no noticeable hit on performance.  I often wonder why it took so long to add cloud shadows since we've had mountain twilight shadows since FS2002, which did not seem to impact performance on iota.  I often think FS2002 was the major shift in simming we had waited for, quite a change from FS98.  It's legacy, such as landclass, is still found in Prepare3d and other sims today.  Clouds were its only weakness but I usually flew with just the realistic looking high cirrus.

Can someone post a pic of how it looks on active sky weather map?

 

Thanks

I'm still using AS2012.  Yes, I know, it's old, outdated, but so am I as well as my computer.  I captured these images of the AS2012 map and the National Weather Service radar mosaic map with just a few minutes between the captures.

From the NWS:

Wow, that's as close as possible I think. Almost a mirror image, looks awesome. 

Hmm may have to make a new weather engine purchase as I'm not happy with what I use, compared to those images.

Thanks for posting.

I found it very realistic too.  Radar images match up almost exactly.

I agree, I am using AS16 and the RW radar images match up very well with what I can see in the X gauge. I have flown into the eye a few times in the past few days using a CS C-130 to simulate 'Hurricane Hunter' flights and certainly the abrupt drop in wind strength within the eye seems very well modelled.  I did however notice that the winds never seemed to exceed 99kts even within the eye wall although they should have been significantly higher and wondered if this was an AS16 limit?

Must be a limit I would presume.  Anything over 100 mph breaks the instruments at times.  I've seen that before in FSX days.

As I'm still flying FSX, you're probably correct!

I was seeing the same thing in the PMDG 737. Wind woundn't go above 99 mph when airborne and sitting at the gate I was getting fluctuations in the airspeed with engines off and config warnings with flaps up along with 80 knots call outs. Taxi was almost impossible at times and it would throw the plane left or right and sometimes I couldn't get it to move when advancing the throttles. Also while airborne I always got pressuratuon failure in auto every time I took off. Anyone else see the same issues?

Is this seriously an attempt to complain about sim physics while trying to taxi and fly a commercial airliner in a simulated hurricane?  Pmdg makes great sims, hi-fi makes a great weather program.  A hurricane is outside the normal envelope of flight conditions.  737's dont fly in hurricanes, and because they don't fly in hurricanes, there's not a wealth of aircraft data available about how 737's handle hurricane conditions for pmdg to base their modeling on.  That said, a lot of things you describe are things I would expect to see if I were trying to taxi and fly a 737 in a hurricane,  the pitot tubes would give the aircraft all sorts of strange readings.

I can get the fascination with trying a sim out in these conditions,  it's fun, but claiming these are "issues" seems strange.

I don't see anyone complaining but merely reporting there findings and how the plane reacts in the hurricane conditions and checking with others. I know that wind speeds effect the pitot/airspeed and that the barometric pressures from the storms will effect the pressurization of the 737. I was making sure I didn't have some crazy settings in ASP4 was my main concern because on a normal flight with thunderstorms ASP4 settings too high can cause unrealistic effects. The only other thing I saw was the windspeed didn't go above 99 so I was wondering if that is a set parameter in the coding or a setting in ASP4. And yes we know the 737 does not fly in hurricanes but when you only have so many options in v4 you fly what you have available.

I didn't attempt a take off within the hurricane as both the missions I simulated involved taking off outside the hurricane zone and flying into it and eventually finding the eye. I couldn't however resist the temptation to try a landing in hurricane conditions but both attempts not surprisingly ended in disaster with a sudden stall in from around 1500ft due to severe wind shear from which I failed to recover. On checking my AS16 configuration settings I had set the maximum level of wind shear well above the default setting which probably didn't help but clearly wind shear is very well simulated in AS16! As far as wind speed is concerned, on my setup I didn't realise that I had left the Maximum Surface Wind in the AS16 settings at the default value of 100kts which might explain why I didn't see the wind rise above 99kts.

With regard to ShawnG's post, I don't think any of us were complaining about simphysics, HiFi Tech (Active Sky is an amazing weather engine) or anything else. We were simply making some observations on what might happen when you try to simulate flight within the extreme weather conditions encountered in a hurricane! We all know that aircraft would not attempt to take off or land in these conditions in the real world but in the flight simulation world some of us enjoy severe weather challenges and a hurricane scenario allows us to take weather challenges to the extreme.

I don't think this would have solved anything, as I had mine set to the maximum of 200 knots and still didn't see the winds go any higher than 99 knots. Somebody said in another post that the instruments taking the wind reading don't go higher than that. I, of course, have no way of verifying the validity of that claim, but I guess it is possible.

the FSX red text menu cannot display higher than 99 but if you use a plane with a display that shows the winds you can see that it goes higher than that.

it's also slightly confusing because if you make custom weather in activesky it won't let you set a speed higher than 99 either for surface wind for some reason. (well, i can think of a good reason which is that you'd never actually take off or land in that i guess haha!)   but you can set if higher for the other wind zones.

i know when i flew through the hurricane i was seeing winds up to 150 or 160, pretty crazy!

here is an example where i set 130 for the winds you can see that the FSX measurement is capped but it shows 130 on the 737 display

I was flying the PMDG Boeing 747-400, and it wasn't showing any higher than 99 knots. I have the surface winds capped at 200 knots. It's weird because I know in the past, I've seen the winds display over 100 knots before.
