FSX simulates aerodynamica and stalls very badly IMHO. To show you how/why I assembled a slideshow you guys might look at closely.

I hope these aren't to many pictures to look at but I want it explained in detail.

 

The test plane Involves a Project opensky Boeing 777-300C with KLM colors

 

Picture 1 (The following pictures involve the mentioned boeing af Max takeoff weight)

Picture 3 (and this picture is the result of my recovery from the stall of the previous picture, FOrgot to throttle back lol)

Now the same Plane also at MTOW but with full flapp settings

And in reaction to the previous picture we got >>

NOTE (LITTLE ERROR ON PICTURE 6 ) In the text on the picture it says it stalled at 140 knots but that should be 116 knots as seen on picture 5. Edited it wrongly.

Again a few pictures but now with emptied weight With full flaps!!

And that was it!!! AND I FIND IT JUST SAID

 

I noticed these things the first time I ever played FSX. Only found it worth my time sharing the details with many other people up till now. I have always searched if these impurities could be fixed by addons and/or file editing.

But cant get the aerodynamical on the internet.

 

So are their ways to make this part of flying more realistic, even if it costed me money.

X-plane simulates aerodynamics better. But I find X-plane in many other ways a much worse simulator then FSX.

 

I welcome everybodys input on the subject.

I think he points out the 'on the edge flaws' of the FSX engine, not so much the detail of the actual plane in use.

 

I doubt that there's a dev in place optimizing his airliner models for that special 'close to' and 'stalling' phase as you mostly fly them times 1.3 and more above that speed. The detail on the normal range of the envelope alone eats up a lot of work and, as so often, one optimization may greatly influence another one. Even more so when the speed ranges of the planes are large.

 

Me thinks the GA plane devs have more to say and develop on that aspect, still being limited by FSX. Their planes fly and land close or beyond that limit, sometimes just for the fun of it. :Party:

 

Find some discussions here. http://forum.avsim.n...gx/page__st__25

Get yourself a copy of the free Aircraft Airfile Manager (google for a download link).

 

Use said program to start editing the airfile. Start with table 404 (Coefficient of lift versus AOA) and 473 (Pitch moment versus AOA)

 

Also learn what Angle of attack really means (it is not the wing angle in relation to the ground)

Anthony, I've stalled your Sierra once. Was trying to come in super close to that limit.

 

Seems like you have some new freeware out. Off to download. Looks very aerodynamic.

The flight dynamics defined for that aircraft are the flaw... not FSX itself. I'm always absolutely shocked when people grab an aircraft, fly it... find it's flight dynamics are off and then claim FSX is at fault.

You guys do realise that if you try and stall a multi million $ LVL-D sim it won't behave exactly like the real thing?

 

If you tried to get it into a deep stall it would behave nothing like the real thing.

 

Boeing does not have the data, hense why training is primarily dealing with approach to stall.

 

So what do you expect from a computer game that costs less then $100?

 

Regards

Have to admit combat sims like DCS and Rise of Flight do handle it better, but those aircraft are meant to go through those attitudes in severe situations.

 

But FSX is better in other areas.

 

Although I'm curious if you tested A2A Accusim Piper Cub yet? Being a simple plane the developers were able to put all their attention to the flight model and engine model.

The flight dynamics defined for that aircraft are the flaw... not FSX itself. I'm always absolutely shocked when people grab an aircraft, fly it... find it's flight dynamics are off and then claim FSX is at fault.

 

Every aircraft, default or downloadable freeware behaves similary bad. So it's easy to suspect the engine if you have no clue untill now.

Im a newb at flight simulator. Not that it indicates or guarantees as much but look at my post count.

I didn't know whether the offscale aerodynamics related to FSX itself or the plane model that im using.

According to your replies it's related mostly by plane model, and I suspected either the game engine or the plane mode. You guys got this one answered.

I did ask for a optional payware fix that by downloading a more realistic boeing model. I have already read about PMDG, and/or Ifly, captainsim and such other realistic models. Ill do more then just look into it (meaning to purchase) when my european toilet placards come in plenty. Now is not the time. But its definetely something for my future wishes.

Ill go look for it and see If I can manually edit it. Ill get back if I fail along the process.

I guess I got AOA explained a long time already.

Wingle angle in relation to airflow along the whole body, not just the wings. YES?

I thought Picture 6 from the OP was a great example of this to show.

 

Thanks for all replies.

No I dont suspect A level D simulator to behave like the real thing, let alone 100dollar sim. But Imho it might simulastor somewhere closer to actual stall speeds rather then a factor off 1.3.

I just assumed that a flight simulator being on the market for that many years would also have its rightfull realism fixes other then terabyte's of scenery addons. But guess this programming is just extraordinary different.

Sorry if my expectations are high met, have no clue on the difficulty of getting something programmed right. Just find a scale of 1.3 away from realism a very easy to modify calculation.

But my ignorance could mean its not.

If you are looking for accurate Vmc,Vfe,Vmo,Vref etc from the FCOM based on gross weight then you are better off using high end products like PMDG. Just don't expect any of those heavy aircraft to be realistic in stall 'behaviour' within FS or X-Plane.

 

Best to treat the high end add-ons as accurate system and procedure study sims and the lower end add-ons as a bit of fun.

If looking for good flight dynamics on coming addon to look at is Majestic Software Dash8-Q400. Their Q300 was already very realistic and used actually by real airline pilots to prepare for testing done in Level D simulators. The Q400 will be even better, and actually calculates its flight dynamics outside FSX engine way that no other addon has done before.

Thanks for the program, but I get stuck at using it.

It doesn't find any airfiles in the directory. Checked it myself and ofcourse there is a Air file. It just isn't recognized by AAM

 

@FScamp

 

Thanks, Ill bookmarked the "majestic software" homepage and check regularly for their new Q400.

Hold on a second. You have tried PMDG NGX or their other aircraft, but now is not the time to buy them? Would you mind clarifying...? How did you manage to test them fully, if you don't own them?

 

If you think there is something wrong with those simple models from Microsoft or Posky (since they don't have a real aircraft simulations, I believe they take most from MS), you are completely right.

Any serious simmer wanting a real performance is going to get RealAir, PMDG, A2A aircraft...

That's right, but AirtankOmega, you may also try the iFly B737 NG, it's maybe not as 95% perfect (perfect as a simulation in this pricerange can be)

as the PMDG B737 NG but really close to it !

I would say at least 88 % and there is another service pack/upgrade (terrain radar) coming soon.

 

(At this moment PMDG virtual cockpit has still better sharpness and perfect textures and really every single button/system is simulated)
