FlightGear is an open-source, cross-platform, flight simulator. The goal of the FlightGear project is to create a sophisticated flight simulator framework for use in research or academic environments, for the development and pursuit of other interesting flight simulation ideas, and as an end-user application.
What's New
Version 2.4.0:

  • Updates to the KLN89 GPS.
  • Tankers now refuel with any callsign, and can enable/disable refueling in flight.
AI system
  • A standalone AI flightplan generator program
  • Approaching aircraft now follow realistic approach trajectories

  • Improved AI ballistics behavior
  • More communication / interaction between AI aircraft and ground. Support for multiple frequencies for AI/ATC interaction.
  • Speed-up for AI traffic initialization by means of an aircraft usage statistics collection mechanism
AI Traffic
  • General and commercial aviation traffic at LOWI airport
  • Malaysian Airways / Kuala Lumpur based traffic
  • Traffic for Adria (Croatia)
Flight dynamics

Environment
  • A local weather system to simulate physically correct local weather phenomena
  • Discard of outdated METAR weather information sources and improved METAR parsing
  • New Fog layers with limited elevation
  • Scenery can be downloaded and installed on-the-fly via an in-sim TerraSync interface
  • Specific multiplayer pilots can be selectively ignored
Interface
  • Complete overhaul of the autopilot system
    • New digital controllers

  • Unified runway selection code that is shared between user controlled and AI controlled aircraft
  • New HLA interface for distributed simulations
  • New on demand loading of Nasal modules
  • New support for external (aka real) Garmin 400/500 WAAS Units
Visual effects
  • Various graphics improvements using shaders, including 3D urban effects, reflections, water, rock textures, lightmaps, skydome scattering
  • Easy GUI-based access to a host of stereoscopic 3D rendering effects
  • Panoramic distortion
  • Persistent contrails
  • New standalone 2D-Panel rendering utility
Bug fixes

Okay, it's free software and all...but does it still have to look like this after 10 years of development? Not to mention the horrid menu system or all the glaringly unfinished business but it's visually a funny crossover between "pre MSFS 5" and "FS 98" and "My First Trainwreck 0.9alpha" with the visual immersion factor of a spreadsheet calculation.

I could be able to write a better comment/review with some remarks on the flight model (no stall possible?) or the function of various systems (if existing) and less ranting about missing eye candy, but I have basically no chance to spend longer than 10 minutes in the program before it crashes in OSX. It's not possible to find out how to start engines from within the program so go KSFO and try to place the aircraft 9999ft in the air - instant crash recipe. Most of the (also unfinished) aircraft crash the sim. When staying on the safe side (flying the C172) it crashes much later though and saves me from the bad experience of a landing in LEGO world.

Of course performance is being decreased by OSX in first place, what the software uses up for drawing the angry unproportional "scenery" is taking the life out of anything lower than a brandnew Mac Pro. If you know how stunningly FS9 performs on an old single core Win computer with a half decent video card, you'll be crying the utterly complete waste of CPU performance you'll be witnessing.

It's all full of what would've been a "good start" 10 years ago, but in this crude form "free software project" becomes an urgently needed apology, not the proud attribute it should be. Yes I know I can try to make it better, but that seems to be the general mistake in projects like this - to assume someone would come and could actually make it better. As we see, too few came and had the skills to make it better and so I don't believe this will ever become as ripe as a commercial product that has to meet standards (as low they may be) and which decides about you having food or not.

I agree, but the problem is MAC. It uses opengl etc. So with that in mind it'll never be FSX. Unfortunately Unix/Linux will never have much for gaming and thats what OS X is. I have seen some fairly good ports in the MAC APP STORE but they are all older games and run a bit buggy. The best I see with a mac was MYST, RIVEN ETC. and PORTAL. For some reason strategy games do well by the MAC but definitely not games that require extensive scenery.

I have an iMac G5 with OS 10.4. When I started to play this game, I noticed that it takes a while to load, and the response time is high. It also froze and program completely shut down right in the middle of it. I'm not a stupid guy either, but I can't even get my plane off the ground!

I'm not sure this should even be a beta release yet.

First the good news. Graphics: OK; close to MSFS (pretty good for freeware, in other words). Sound: Good, but then flight sims aren't the most complex soundtracks on the planet. Stability: takes a long time to load (about 2 minutes) and appears to be the pizza of death, but after the screen changes resolution and aspect ratio a few times it seems to work reasonably well (is the splash screen supposed to tear up like that?).

Now the bad.

User interface: horrid. Not just the "ported-from-UNIX-ugly-but-works" style, I mean pull-down menus that don't do anything except tell you to use an XML editor to edit the preference files (hacking is fun, but shouldn't be mandatory). Major settings like screen resolution and controller options seem to be inaccessable from inside the game.

Physics: I managed to roll through the terminal building on a take-off run, did an inverted loop (in a 707!) and flew straight through the ground, which then disappeared leaving only a black dot. For me, detecting collisions with ground objects is a major part of the "simulation" aspect of any flight sim. Its harder to make a comment on the flight models, since my machine (eMac 700MHz, 32MB nVidia, fine according to the limited system specs on the HTML manual pages) couldn't manage more than about 8 fps (guessing, the fps display didn't seem to work), and the poor UI design meant that changing the settings was too much of a chore*.

Installation: "Drag the FlightGear folder to Applications" say the (rather meagre) installation notes: this I tried, and got a permissions error. Fixed with "Get Info". The other problems I can forgive as development issues, but this is just plain carelessness. Found no other relevant documentation on the DMG, just some bible quotes, which were absolutely no use under the circumstances (praying DIDN'T help...).

Frankly, if this software is actually used by anyone in the groves of academe doing serious research, I'm never flying again! For now, I'd suggest sticking with Warbirds or X-Plane; they may not be open source, but they work...

*I'm one of those old-fasioned people who believe that computers are supposed to make life less complex and more enjoyable, not the other way around.

Addenum to previous review:

FPS counter does work, but is unlabelled and hard to find. Perhaps it shouldn't be on the instrument panel...

Necessary to exit game to change plane.

Mysterious crash (program, not the plane) after changing planes (opening dialog box, splash screen, sound, then nothing).

Does detect ground collisions, but only with landing gear down. Plane can get stuck at odd angles, only option is to reset the simulator.

Some menus do work, but many settings don't appear to do anything. Settings aren't retained (surely there has to be some GPL source code for XML editing out there...).

Default controller setting maps the throttle to the joystick "Z-axis". Impossible to change, because it STILL won't copy to my hard drive (argh!).

Still runs like a cow (and I don't mean with bells on).

And it was a 737, not a 707. It still flies underground, though, and it feels way too responsive (more like a Lear Jet).

I've played this on FreeBSD on both a thinkpad
and a desktop machine. The last stable
version (from my experience) was 0.9.3.
After that, it has been very unstable
(memory leaks) and crashes regularly.
So it doesn't surprise me that the OS X
port gives people a bad taste in their
mouth. On a reasonably fast machine
(in PC terms, >2GHz) with a video card
that does direct-rendering, and back when
it worked well, it was one of the most
realistic flight simulators around. The
keyboard interface is hard to get used to
but it did work (at one point). Serious
flyers used a joystick. Hopefully, they'll
get the bugs worked out...soon.
Perhaps we can convince the Fink project
folks to try another port of this (although
I can't blame the person who ported it,
I think it's been unstable since 0.9.6).

Downloaded it and the darn thing wouldn't open.

My computer meets the requirements.

It now rests in the trash. Sad really because it looked like it would be a ton of fun.
