Windshear and ASN

Recommended Posts

Any intention from the developers to create a WORKING windshear detection system in the NGX? Now that ActiveSky Next will have windshear, the excuse that "FSX does not simulate a windshear" is no longer valid...

Cart before horse issue.

 

It's no longer valid if they pull it off.  I'm optimistic, but it's not really fair to say various limitation arguments are no longer valid when the final product hasn't been delivered yet.

 

I think it's best to wait for the product to live up to the promises before jumping to conclusions.

From the Video they posted it looked like a complete joke, really terrible. I have a lot of respect for the AS developers but they need to do better then that. At least it is still in Beta so they have time to improve the system, I doubt very much they can pull it off with such a limited engine.

I can't understand based on what you say it's a joke... Further, the beta is almost over, ASN will be released in 5 days....

have you seen the video posted on the main FSX forum? The video entitled MICROBURST that consists of a 767 happily rolling down the ILS in some moderate chop with GPWS shouting Windshear Windshear! :)

Yes, I've seen it, if I remember well the airplane performs a go around in the end... What's wrong with it?

I already explained what is wrong with that vid over on the main FSX forum.

 

1. Real life microburst - At first windshear callout, set TOGA thrust and follow the windshear escape procedure, likely whilst fighting the stick shaker and praying.

 

2. Active sky video - cruising down the ILS, Windshear warning sounds around eight times with no pilot reaction, aircraft behaves like an average day into Tokyo, no sink rate, in fact nothing even mildly threatening about the weather. He does go missed because he is screwing up the approach.

 

Anyway good luck to the guys at AS! I will still be purchasing, just taking a lot of the hype with a pinch of salt, with the amount of weather addons available they all have to shout about being the next big thing.

 

Regards

If it was possible to ask the Delta 191 (KDFW 8-85) crew they would tell you it is a life and death struggle and not a couple of bumps in the road.

Exactly.  I think a lot of people assume that I'm trying to take them down or something because I keep holding out on getting excited until it's released.  Having seen claims about groundbreaking advances before, I know how people latch onto the hope that their dreams will be answered, only to be disappointed later.  I'll still buy it for the other advantages it'll bring to the table (because most of those are improvements on earlier versions), but I don't think people should be posting topics like these in the assumption that all problems will now be solved by the program before even seeing the final product.

Talking about  the wind shear warning and using  asn I got it  using the other aircraft which iam not going to mention,  I got the audio warning  when taking off in thunderstorms

You mean this one:

?

 

Hardly just mild chop or happily rolling down the ILS. It looks like a textbook micro burst with headwind followed by tailwind. Ended up full scale below the glide with  -2000 fpm and bouncing off the barbers.

 

I don't know what the 767 product is, but the weather radar showed predictive windshear, the call was for reactive windshear and seems to chime in a before the effect became apparent, which isn't my experience in real life.

 

The video appears to be manually flown to demonstrate the effect rather than demonstrating procedure or a/c systems so I wouldn't read too much into the actual flying.

 

All in all, I would say that that ASN effect is pretty good!!

Does that look like a 767 to you? :)

 

 

Edit - It seems AS have removed the old video from youtube, very good move, the video was terrible! I have feeling some overly excited beta tester posted a video before the product was completed.

The ASN W/S calls are 'predictive'; I got up to five of them during an approach before actually encountering it. After the fifth callout ASN smashed my B744 to the ground ... (ASN with first SP applied)

If it's predictive the call out should be 'Windshear Ahead' But that is down to the aircraft developers I suppose.

 

Nice videos, looking forward to purchasing in the new year.

 

Havent flown my sim in nearly six months, does anyone know if ASN is changing behaviour on VATSIM/IVAO? Hardly anyone would bother to divert or request vectors around cells previously.

I haven't seen it yet, but I haven't been online too much recently.

1. Yes, predictive windshear does exist in the 767 (mode 7)

 

2. Trust me, Level-D sims don't really get the "nack" of the microburst. Just allows us to practice the escape/recovery procedures. A lot of sim instructors must experiment with an "intensity %" to get the simulation just right. 

 

3. Hats off to HiFi for integrating another "threat/challenge to flying" that didn't exist before.

ASN now make thunderstorms scary. I flew my ngx through a cumulonimbus to see what happens, well it was an interesting ride. I especially like the hail effects and sound as you reach the top of the anvil.

So now that we've got all the bickering out of the way, is the windshear simulation accurate enough for PMDG to take a look at integrating it?

Out of curiosity, I noticed in both vids that the wind speed did not change, and only the wind direction changed "slightly".

 

Anyone with knowledge care to enlighten me/ us?

I am referring to real world here, not ASN.

 

Thanks for the information.

The definition of windshear is an abrupt change in wind direction or speed in a relatively short amount of atmospheric distance.  As such, you should see a significant change in either speed or direction.

 

In the video, the wind direction changed over 100 degrees.  I wouldn't exactly call that "slight."  At the same time, I wouldn't call the demonstration a strong one as the change was relatively slow, at about 30 knots through the sweep.  Then again, depending on how the default 737 simultation calculates wind, the display could have been lagging behind actuality.

Always there with a fact full answer Kyle, thanks.

 

I did not pay too much attention to the video's so I stand corrected on the slight comment.

 

No idea why I forgot the wind direction out of the formula.

 

BTW, thanks for the uploads on you tube, quite helpful.

It's not as obvious as speed, but when you think about it, the direction is essentially a delta in speed.  A 30 knot headwind that quickly becomes a 30 knot tailwind is a 60 knot delta in velocity that could be rather dangerous on approach.

Welcome!  Glad people are finding them helpful!  If there's anything you'd like to see, let me know!
