X-Plane Flight Simulator For Linux
sho-gun writes: "It seems that Austin Meyer, creator of X-Plane, is going to be porting his simulator to Linux. X-Plane is an incredible flight simulator which models flight dynamics by using blade-element theory. Many big companies use X-Plane for development. Currently only the support programs (the programs that build the planes, scenery, airfoils) are available but the full application should be available soon, according to the website. Along side with the open-sourced
Flightgear,
this certainly is good news for flight simulator fans
that use Linux."
Uh.. slashdot is not just about free software.
Xplane (the world's most accurate flight simulator you can have without a military budget) being ported to linux is *fantastic* news.
Not everything needs to be free, bub. It's only free if people are willing to write it for free.
It's never perfectly debugged but it's also never stopped adding cool details, features and stuff. These get divided among flight model features and eye candy. In the former category, Austin (yes, this is all ONE GUY coding it) added support for gyrocopters. (It's _always_ had helicopter support, which is rare). In the latter category, he's been enhancing the clouds and scenery hugely- even 5.66 (not the new version) already has very impressive 3D clouds, which don't even eat the frame rate that much.
The true geek factor in X-Plane is not even flying the planes- it's designing them. Using all the tools like Part-Maker, Plane-Maker (and these need to be included, 'scuse me for stating the obvious) you can literally design just about anything, right down to designing your own _airfoils_, using various third-party stuff to determine lift/drag/moment of the foil at various angles of attack, and then entering that into Part-Maker to bring the airfoil into X-Plane for use. Plane-Maker is about placing wings and elements anywhere, NOT about punching in 'stall, top speed' etc values: the utterly amazingly geeky thing about this sim is that it builds the flight model from just analysis of the plane parts, ten times a second, relative to things like AoA and speed and propwash and ground effect. So when you put something together in Plane-Maker, and it doesn't exist in the real world, you're actually using X-Plane as an aeronautical design tool, and instead of working out on paper whether the CG is too far aft, you save the plane, fire up X-Plane, 'get in the drivers' seat' and take the bastard up and see if it kills you ;)
That's about as cool as virtual reality gets, right there- and it's the heart of the geek appeal, to me: if you play with the sim this way you have to _be_ capable of interpreting behavior like a test pilot. The planes behave in amazingly unexpected ways. I've had a high-speed jet show a nasty tendency to pitch up sharply at a certain speed- puzzling until I realised that it was hitting Mach 1, and the shockwave was interacting with the wing geometry (!) Try _that_ in MSFS or Fly...
I've actually taken ideas from Slashdot into X-Plane: some time ago there was an article about Japanese ground-effect flying trains, so naturally what do I do? Go fire up Plane-Maker, and try to build a ground-effect vehicle that maintained a consistent ground height all by itself. Didn't quite succeed, but I did manage to make the most forgiving aircraft I've ever seen for zooming about really close to the ground... and now there's gyrocopter support, there's lighter-than-air support (and the Hindenburg), and the helos (and the SoloTrek- yes, the two-ducted-fan thing that you stand on), and whatever neat aero thing turns up next year on Slashdot, I am sure X-Plane will be able to handle modelling it. Hell, there's even an entirely fictional Japanese Anime Plane to play with. I flew it straight up into space and the stars came out, in a perfectly black sky, as I passed escape velocity. Now if we could model something _real_ that does that, we'd really have something...
Think of it as a commercial aviation design simulator for less than $50. There are in fact a _number_ of people using it to rough-draft real-world planes being built in real life... suffice to say, X-Plane getting a Linux port is _totally_ news for nerds, and if you're an aero nerd it is very much stuff that matters. It's probably the single coolest program I have, of any description. If you want a specifically opensource flight sim, Flight Gear has a lot going for it- but if your interest is strictly aviationgeek and not coder, X-Plane absolutely maims anything else out there, by a wide margin, even given that it's usually kinda quirky (5.66 was running nicely for me, though).
