On behalf of the Fly.Simvol team, I have the huge pleasure to announce that after several years of development and hard work, the 1st public version of Fly! Legacy (0.3.3 alpha), the opensource flight simulator (written in C++ and using OpenGL) based on Fly! II, the Terminal Reality's flight simulator of the early 2000s, is now available for download on Fly.Simvol (http://fly.simvol.org/indexus.php).
If you are interested, you can also download the source code of the project at this address:
http://sourceforge.net/projects/flylegacy/

This software has been mainly developed by Chris Wallace, Jean Sabatier, Laurent Claudet, Luc Lion, Didier Rigault, Frank Dhont (other people also took part in this project) and it is currently in development stage (alpha version).
The work was huge because the first step of the development consisted in reproducing a software which has the same behavior than the original simulator, and which used its databases.
After that, came the second step which was to make the new simulator compatible with all the third party add-on developed throughout the years by the passionnate users. This makes it possible to use sceneries, aircraft and plugins available on the different websites.

Thus, the core software is centered on the Cessna 172 (from TRI) which was set to work as well as possible. Other aircraft can be easily adapted and we hope that a strong cooperation from the community to help us in this task.
Today, the software is operational, but the intial project evolved: the idea is now to make the software independant from Fly! II, in order to allow a majority of users to take part in this project. For this purpose, the migration to SQL databases was made possible.

Besides, this 1st alpha version (mainly targetted for developers) has a limitation (which will be removed in future versions): currently, Fly! II is still needed (7-8 files), but we are working to remove those last dependencies. Nevertheless, all the developers are welcome to help us complete this complex task as soon as possible.
It is therefore important to keep in mind that bugs may remain and that some features have not yet been developed.

Those tempted by the project can help us using various skills: C++ development, 3D objects designing, user interface, and so on... If you are interested, then you can contact us or post a message on our forum (http://forum.simvol.org).

Note that Fly.Simvol is now present on:
- Facebook (http://www.facebook.com/pages/FlySimvol/143471495687327)
- Twitter (http://twitter.com/FlySimvol)
- Ustream (http://www.ustream.tv/channel/fly-simvol)
- YouTube (http://www.youtube.com/user/FlySimvol)
We invite you to show your support to the project by following us on these different websites.

In any case, we strongly encourage you to post your comments, critics and bug reports on the Fly.Simvol forum (http://forum.simvol.org).
Let the adventure begin and have a good flight !

I personnaly asked Stephane to post this announcement here.
As a user of PS1.3 (by the way, as it is my first post, I love it Hardy - and I am very excited waiting for PSX), I think there might be an opportunity for future connections between PSX and Fly! Legacy.
FL will be a complete stand alone simulator, opensource, and all OS compatible.
Maybe this is something to keep in mind: when FL will be out of alpha version, it may be interesting to try to link FL visual to PSX.

It would help immensely if the Fly! developers include a specific option (not a hack) to disable the complete plane and only keep a camera flying over a planet. If they allow the camera to be pitched, banked, and slewed in 3D around the planet, and update the planet with some weather and other natural phenomena, their program will be very easy to interface to PSX and other dedicated plane simulators.

The distinction plane simulator versus planet simulator is key in getting good stuff, I believe.

... and allow to send out the local scenery elevation to PSX.

If PSX's internal scenery is not used, the external scenery's current elevation is required for PSX's radio altimeter model, aerodynamics model and weather model -- at an update rate of at least 1 Hz.

Fly! is open source, and of course that brings great advantages. But did anything ever come of the brief contact with the Outerra group? http://outerra.com/

They have a planet simulator with a hovering camera and no airplane... in fact, they built their planet simulator precisely for uses like this.

EDIT: The Outerra people are thinking that the virtual planet could be shared by many simulators: "Also we'd like to try a different model eventually. Making a platform that is open to all developers, allowing sharing of content they create within common realms. For example the makers of various simulators could use the same world, just providing their specific game code and models. Imagine you could see various machines within the world... The world will be alive with people driving the machines."

I think the most important criterium for "universal scenery generators" is the availability of aviation related scenery objects: airports.

If generator A has 1000 airports and generator B has only 1, then there's no reason to prefer B over A.

How do scenery developpers store their design work? Are the coords and textures stored in a platform independent data base? If so, one could, theoretically, convert any scenery specifically for MSFS, X-Plane, FlightGear, Fly, Outerra etc.

After all, a coord is a coord, a bitmap is a bitmap.

Since my last message, the situation changes a lot. Indeed, we have published a new version 0.6.5.1 which brings important new features, as the Cessna 172 HD, the virtual pilot, a more realistic flight model but also, Fly! Legacy is now totally independent, it is not necessary anymore to have Fly! II.

My guess is that Cascade Game Studio is developing a world simulator for Microsoft. It would have to support all of the other vendors' airport sceneries if it wishes to have a head start. In this scenario, another open world simulator is going to find it very difficult to get airport sceneries established.

On the other hand, supporting all existing sceneries means having enormous difficulties moving forward. Being Microsoft, I think they simply abandon everything there is, start from scratch with 100% proprietary interfaces and data, and offer licenses and co-packaging coupons for the scenery developers to come and join the new club.
