I fly mostly in Asia and my 'OMG' experience was when I saw these scenery:

 

 

 

 

 

 

Oliver, I'm pretty sure you're confusing the context of this thread.

Anyway...

I was seriously impressed with this video.

Darn nice wing-flex on landing. Do you know which aircraft that is?

I believe Oliver is not using the right rendering settings...

 

Oliver, did you check the "Grow buildings downtown" box in the rendering options screen?

 

But, of course Oliver also knows that in X-Plane10 we can expect this sort of stuff and even this,

or THIS ... so... that's it, he forgot to "tick" that checkbox...

That's my gripe. It shouldn't buffet like that.

 

I think it's important to ask if the buffet seen on this video is intentional, or something else?

 

The F-22 is my go-to airplane when doing some X-Plane testing work as it can get to a location pretty quick in leiu of X-Plane's inabilty to slew. The ONLY TIME I've seen the default F-22 bounce like that was when I had my "flight models per frame" set too low. Otherwise, the default F-22 in that video flies smooth and steady as silk - "on rails", as it were. Only after upping the "flight models per frame" value from 1 to 2 (or 3) did I have the ability to fly without chattering my teeth.

 

Flying that fast in an aircraft that small will always have some buffeting.

 

However realistic it might be when compared to real-world videos, the chattering seen on the F-22 NOE Bryce Flight is more than likely unintentional but fixable, and a result of the computer being overtaxed and not having the cycles needed to work out the flight dynamics.

 

I think you're both right - in my X-Plane experience the F-22 certainly does not buffet like that, but only after making the "models per frame" system tweak. A real-world fighter certainly will buffet like that, but I've never experienced that type of vibraration modeled in any sim, including X-Plane.

Okay, that explains it. I usually have my flight models at 2, but I turn it down to 1 when I fly the 777 due to my computer being on the lower end. I just forgot to set it back when I did that flight.

euhhh, where is this option? If it was a joke, you got me...lol

Default 747-400

Did you watch the videos, Larry?

I'm very interested in your feedback and opinions on the buffeting in real aircraft and how strikingly similar it is in X Plane.

 

First off, I'm happy to see, that the F-22 problem in the video was easily taken care of. As to video's, yes I saw these, and watched plenty of Blue Angles in- cockpit video, as well as some P-51's, and RV's. While there is going to be some buffeting under certain circumstances, a lot of the footage is smooth, without helmets being knocked side to side. In fact, the helmets appear quite still. My own P-51D Mustang experience at close to 400 mph was quite smooth. It also included loops and rolls.

 

I also looked up the history of F-22's. The early models had buffeting, caused by turbulence at the intersection of the twin tails & fuselage. Computational fluid dynamics didn't discover the problem before the aircraft was built. (Perhaps, if they had only just used X-Plane ) Since this would cause premature fatigue, the area was redesigned along with a software change.

 

The following video is from a tail camera on an RV (the type I fly). It shows the smoothness, I talk about............even though speeds will be just a bit less than 200 mph.

As it stands, every time I see your name in a thread, I roll my eyes and say to myself, "Well, here we go again." I say this not to be a jerk, but because I think it needs to be said. I'd wager a pint or two that there are others here who feel the same way, and I'll accept the responsibility of speaking for them as well.

 

I'm sorry you feel that way. Last week at Flightsim com................I was told that desktop flight sims can no way approach real flight whatsoever, therefor my crusade for improved flight dynamics was a waste of time. They too, were sick of anything I had to say. I'd hope you don't feel that way. I know that Goran, Morten, Tom & some others, certainly care about the best flight dynamics possible for XP........as well as all of those who designed for MSFS that I beta tested for. We were always attempting to up the bar. I'm very well aware of the limitations of desktop software, but know just how close it can get to real, too.

Well, quite on the contrary, and even if sometimes it may look like I am allways refuting what you say, I allways read and try to understand (from a perspective of someone who loves flight simulation, flies for real but only gliders, and has no degree in aeronautical engineering) what you and others say when you try to explain what you don't find right about X-Plane10 (in this case).

 

In the first place, you have a lot more flying experience than I have (that's an easy one...) on prop aircraft, but! you also have experience in building your own aircraft, and you're a dedicated MSFS user (probably of other sims too). All I have to accept/understand and try to use in a positive way is that, should you find everything is perfect with X-Plane, you would certainly be using it as your only simulator. If not, than, most certainly you find in MSFS aspects that are worth the use, and that is only what I have to understand and accept...

 

All I can do, for instance, is try to find some time to edit the RV6 that comes default with X-Plane10, and bring it to a performance that you may find plausible. Before investing on that, I still have a loooong way to walk because, I have really just started (re-started) with X-Plane ;-)

 

Please keep posting your comments, constructive negative or constructive positive - they are welcomed at least by me :-)

I own X-Plane 8 & 9. Use the 10 demo, and have four payware X-Planes. I believe it gives me the right, to dispute certain statements here and there.

 

Cool. As far as I'm concerned, you're OK to post in this forum then as long as you were/are an owner of X-Plane.

Yeah LarryA, don't go away, I like to listen to you, and have for about 10 years or so. :smile:
