That's Not Correct --TOO SLOW!

Recommended Posts

Hello friends,Helicopters either the default ones and others like in the first pix below they just FLY TOO SLOW in the Outside View. :no: So I wonder if there's a way (in the aircraft cfg perhaps) to correct that and make it a bit more realistic speedwise (at least like the one in the third pix). ANY ONE KNOWS?http://i151.photobucket.com/albums/s133/di...23-1-41-296.jpghttp://i151.photobucket.com/albums/s133/di...2-23-14-734.jpghttp://i151.photobucket.com/albums/s133/di...6-11-33-593.jpgI appreciate your inputs.dito

Well actually helos in FSX aren't really that far off regarding speed, if at all. The Bell 206 jetranger for instance has a top speed of about 120 knots, pretty much right on the money in the sim. Drag aside, all helicopters are ultimately limited in their top speed by a phenomenon known as retreating blade stall. The short version is that if a helicopter flies beyond a certain speed the blade that is rotating past the nose and beginning to head towards the tail can actually find itself flying at zero velocity relative to the oncoming air, or even backwards through it, resulting in an enormous lift imbalance between the two sides of the rotor disc. The end result is pretty much like a spin in a normal aircraft, except much more violent and for all intents and purposes unrecoverable, more than likely leading to blade or rotor hub stress failures.Some military helicopters have a somewhat higher top speed than the average civilian one, ie: AH64 Apache/longbow and MD-500, because they trade some fuel economy for a significantly higher rotor rpm, offsetting the onset of retreating blade stall.However, if you're not satisfied you can tweak the parasite and induced drag scalars in the aircraft.cfg file to your heart's content. Aside from translational lift FS doesn't really model any of the unique quirks of rotor discs very well. :)Cheers.

I think the OP meant the pan rate while in external view. ??Not top speed of the helos... ??RhettAMD 3700+ (@2310 mhz), eVGA 7800GT 256 (Guru3D 93.71), ASUS A8N-E, PC Power 510 SLI, 2 GB Corsair XMS 2.5-3-3-8 (1T), WD 250 gig 7200 rpm SATA2, CoolerMaster Praetorian case

>I think the OP meant the pan rate while in external view. >??>Not top speed of the helos... ??>Hmm, I thought he meant speed as well. If not, can't you alter the exterior/spot pan rate in the view tab?Regards, MichaelKDFWNot anti FS9, just pro FSX!

>I think the OP meant the pan rate while in external view. >??>Not top speed of the helos... ??Nope. He indeed meant the visible apparent "speed" of the helo across the scenery.It's a classic error induced by spatial orientation and perspective, not at all unlike the very FIRST comment folks make when I show them my basement HO empire:"Can't those trains go any faster?""Say what? They are moving at 60 (scale) MPH! :)

Well that's what I thought was meant, but I'm still stumped. The heli in the third picture isn't going any faster than the other two. Least not visibly so. I stayed up all night staring at these pix to catch some kind of movement - anything - and according to the measurement's I've taken over the last 10 hours, they're all right at (or VERY close to) exactly ZERO knots airspeed. Around 04:30 the one in the second pic did finally start to move but didn't get very far, and now seems to be back where it was at the beginning.If someone can take over the next shift and keep an eye on 'em, we'll get this figured out I bet ya. Might need a round-the-clock effort though.

>That's EXACTLY what I meant:the visible apparent "speed" of>the helo>>across the scenery!OK, in that case it is simply a matter of both zoom level and perspective.The further out you are zoomed, the slower the helo will appear to "move" with relationship to the ground.Likewise, the higher the helo is above the ground, the "slower" it will appear to move with relationship to the ground.In fact, you don't even need the sim to observe this effect. Next time you're in a car, notice how "slowly" objects far away seem to "move" in relationship to the car's speed......then notice how FAST closer objects are moving! ;)
