Welcome to the FlightGear Newsletter!
Please help us write the next edition!
Enjoy reading the latest edition!


We would like to emphasize that the monthly newsletter can not live without the contributions of FlightGear users and developers. Everyone with a wiki account (free to register) can edit the newsletter and every contribution is welcome. So if you know about any FlightGear related projects such as for example updated scenery or aircraft, please do feel invited to add such news to the newsletter.


FlightGear events

Anticipating LinuxTag 2011, the most important place for Linux and open source software in Europe, a Video Contest has been started at the forum. We have strong evidence that, again FlightGear will be present at the show with it's own booth and the FlightGear presentation team is looking for a video to present the best features of FlightGear in a short movie during the show. The creator of the chosen video wins one of the rare and famous FlightGear t-shirts, a pair of cool 3d-red-cyan glasses and free admission to the LinuxTag 2011 in Berlin, Germany. Deadline for entries is April, 24th 2011 12.00 UTC. read more..

Sound files for 3D Audio

There seems to be some confusion about what types of sound files are supported for 3D audio rendering. Let's explain a bit more about how 3D audio works.

A 3D audio, or spatialized audio, implementation consists of one listener (like the OpenGL viewer) and multiple audio sources. A listener is placed at a specific location and has an orientation (view direction). Sources are placed in the scene at their own location and have an emission direction which is used to calculate the sound cone for non omni-directional sounds (sound sources that sound louder in one direction and softer or even quiet in the opposite direction). Sound sources can best be seen as a single dot emitting sound waves.The relative positions of the sources and the listener is used to calculate where the sources should be positioned in the listeners sound sphere.

If a sound source would be anything but mono it is almost impossible to guess how to handle all the channels in 3D space;

  • Do they get mixed together?
  • Do the tracks get positioned with a slight offset to each other? This in effect means mixing them together when the source is not close to the listener.
  • Do they get positioned at the same location but with a sound direction offset of 180⁰? This means mixing them together if the sound is omni-directional.

There is something to say for any of the choices but you can bet that if one of the three was chosen someone else comes by and wants it to be different.

For this reason it is specified that only mono files will be used for 3D audio processing and stereo files will be mixed using the stereo mixer instead. Trying to set a position or direction for a stereo file will result in an error like:

Failed to load WAV file: Unsupported mode within an otherwise usable file type

New aircraft

OH-6 Cayuse

Icecode and Star have started developing the Hughes OH-6 Cayuse. OH-6 Cayuse (nicknamed "Loach", after the requirement acronym LOH - light Observation Helicopter) is a single-engine light helicopter with a four-bladed main rotor used for personnel transport, escort, attack missions, and observation.

Updated aircraft

Pilatus PC-21

pjedvaj and Johan G started to work on Pilatus PC-21. FDM will be the same as in original package with new systems and animations added. It has a new high-poly 3D model. New landing gear models and liveries are being developed. Final release will include all glass cockpit with MFD's and HUD. Temporary cockpit in this development stage has only a generic 2D panel.

pjedvaj resumed his work on Mikoyan-Gurevich MiG-21bis. Rudder issue is fixed and GSh-23 gun is now fully functional. Further development is concentrated on cockpit and instruments.

Airports

LIMW Aeroport Regional de la Vallee d'Aoste "Corrado Gex", Aosta (Italy)

LIMW Aosta (pic by F-sig)

Another small airport in the Alps, for those simmers who like VFR within mountains, like the Monte Bianco (Mont Blanche) and the Cervino (Matterhorn).

The updating started with the extension of the taxiway to the end of rwy 27 (to reflect works recently done in the reality); the new LIMW.dat has been already forwarded to Martin. The modelled buildings include:

  • The Control Tower
  • 3 old fashioned Hangars
  • The new hangars (some 130 m long)

The sliding doors of the 3 old hangars move to shutdown position at sunset (nasal script developed by ot-666).

The above model are already included in the Repository.

And finally ...

The FlightGear presentation team is asking for your help! To be able to continue the excellent work at events like FSweekend and LinuxTag and to keep the allways growing equipment up-to-date and running, a PayPal account for donations has been set up.

If you think, they did a good job at presenting and promoting FlightGear and if you want to support them in having the best booth during the show, please consider donating a few Euros, Dollars, Pounds, Crowns, Yen, Francs, Afghanis, Dinars, Pesos or whatever your currency might be to donations@flightgear.org using PayPal.

All donations will be used for the sole purpose of adding to or maintaining the equipment used at the shows. Donations are not tax deductable yet.


Contributing

One of the regular thoughts expressed on the FlightGear forums is "I'd like to contribute but I don't know how to program, and I don't have the time". Unfortunately, there is a common misconception that contributing requires programming and lots of free time. In fact, there are a huge range of ways to contribute to the project without needing to write code or spending days working on something.

For ideas on starting to contribute to FlightGear, you may want to check out: Volunteer.

Call for volunteers

The OpenRadar project is looking for a new maintainer.

The TerraGear GUI project is looking for programmers to help create a GUI frontend for TerraGear [1].

The FGFSPM (FlightGear Package Manager) is looking for a new maintainer.

Reminder: Google's Summer of Code 2011

FlightGear project is planning to participate in GSoC 2011. However, doing that really requires a fair amount of work, planning and organizing. This is not something that can be done by a single person. It really needs a coordinated team effort, or otherwise FlightGear won't be able to apply/participate at all, and has not participated in past years.

So all users are invited to help us progress further with our preparations for GSoC 2011. If you have any questions or other feedback, please use the forum to get in touch.
