FlightGear Newsletter December 2023
We would like to emphasize that the monthly newsletter cannot live without the contributions of FlightGear users and developers. Everyone with a wiki account (free to register) is welcome to contribute to the newsletter. If you know about any FlightGear related news or projects such as for example updated scenery or aircraft, please do feel invited to add such news to the newsletter.
The new Visual Editor makes editing the wiki as simple as using a Word-processor, and even easier than using the forum as you don't even need to know the syntax for a url. Just hit the 'edit' link and start.
Gyro based instruments enhancements
Alot of work is currently ongoing by Benedikt and James regarding the gyro driven instruments implementations.
Limits and gyro characteristics where hard coded, and this will be exposed to be configurable in
instrumentation.xml as well as at runtime using properties in the instruments tree.
Also, the heading_indicator_dg will get support to be either electric or vacuum driven by configuration in
It also got more realistic erorr simulation, like transport wander and precession erros (the latter can be countered by a latitude nut), but also gyro tumbling by over-g (resulting in spinning of the DG). That DG now also can be caged.

Idea to integrate FGCom-mumble into the core using libmumble
Recently, live came into the idea to integrate the mumble based VoIP solution into the core. Over the years, there were from time to time such toughts, and maybe, with the dawn of libmumble, it could be made real this time.
This would surely need help of someone capabable in c++ as well as the build chain of flightgearand cmake.

NEW AIRCRAFT: Dassault Mirage G8
Dassault Mirage G8 (by helijah) DOWNLOAD
Experimental heavy fighter aircraft with variable geometry wings, two-seat, twin-engine, long-range.
The basic version of the Mirage G evolved into a larger and heavier two-engine, two-seat version for attack missions: the Mirage G4. The G4-01 would later be converted into the G8-01 and the second aircraft (G4-02) converted into the G8-02. The G8 variant was equipped with a Thomson-CSF radar based on that used on the SEPECAT Jaguar and Dassault Milan.
The Mirage G8 was equipped with two SNECMA Atar 9K50 engines, which allowed it to reach Mach 2.2, climb up to 18,500 m and cover a maximum distance of 3,850 km. This superb device turned out to be too expensive and complex, so it was not mass-produced, in favor of the successful and simpler Mirage F-1.
NEW AIRCRAFT: Northrop YB-49
Northrop YB-49 (by helijah) DOWNLOAD (FGAddon)
Strategic bomber prototype in "flying wing" configuration. A plane ahead of its time:
"...The Northrop YB-49 was an American prototype jet-powered heavy bomber developed by Northrop Corporation shortly after World War II for service with the United States Air Force. The YB-49 featured a flying wing design and was a turbojet-powered development of the earlier, piston-engined Northrop XB-35 and YB-35. The two YB-49s actually built were both converted YB-35 test aircraft. The YB-49 never entered production, being passed over in favor of the more conventional Convair B-36 piston-driven design. Design work performed in the development of the YB-35 and YB-49 nonetheless proved to be valuable to Northrop decades later in the eventual development of the B-2 stealth bomber, which entered service in the early 1990s..."

C172p / C182s/t: Towbar for ground handling
The C172p and C182 development versions got a new Towbar feature.
Basicly, when attached, you can click on it and by moving the mouse you can pull/push the plane around on the ground:
- Most fun with the walker! Stay in front of the pane, oriented towards it
- Click the bar and hold the button.
- Moving the mouse left/right adjusts direction.
- Moving the mouse upwards (away from you) pushes the bar, downwards pulls.
- Releasing the button will release the forces.
Especially when pulling/pushing, give the plane time to react. It is heavy and this is simulated.
If it wont move, check that securing like chocks and tiedowns are removed and make sure the parking brake is not set. Also, when on rough surface, you might not be strong enough to move the plane by hand.
Post LTS work
After the 2020.2 release, some work lies ahead to improve the LTS and to help us pave the way for migrating to the OpenGL Core profile - any help would be greatly appreciated.
This may for example include:
- Switching to the OpenGL Core profile:
- Checking that aircraft work with the LTS and documenting any major problems
- Include ffmpeg libraries in Windows and Mac builds, to enable built-in video encoding.
- Cppunit effort and FlightGear Headless (see Testing)
- Deboosting FlightGear
World Scenery 3.0
Aerial (drone) photos for Terrain textures
Wanted: good top-down aerial photos to create textures from to use with the procedural Regional Texturing system. with cameras are ideal. People with access to drones are in a good position to take high-quality photographs.
A particular need as of 2020 is photos of agriculture (farm lands) from different parts of the world.
Good GPLv2 compatible photos suitable for textures are hard to find, and an easy way is for people to take photos of their region. Flightgear's procedural systems can do a lot with less art content, so photo contributions can strongly improve visuals.
Photos of trees for textures
Wanted: good quality photos of different trees and vegetation from various parts of the world. Flightgear's vegetation system can handle multiple layers of trees and bushes.
Strong shadows should be avoided. Each tree should be against a background of a different colour: sky (preferably) , clouds , or buildings. This allows the tree to be separated from the background in a photo-editor like GIMP.
Submissions of labels for craft
Wanted: Submissions of labels (tags) giving a rough description of aircraft - Metadata tags. A quick read of a craft's Wikipedia page will normally be enough to set labels. This info will be searchable from the launcher GUI. For example, filtering craft by propulsion like single-propeller or 4-engine jet craft, or by a manufacturer like Airbus or Grumman, or by speed like supersonic craft, or craft by era like WW2. A list of tags is here - more can be added if needed. To add tags to craft yourself, the tags are stored in the set-xml file.
Windows Package Maintainer
The core team needs help from Windows users able to maintain a good working Windows build. This process already exists to support our Nightly and Release builds, but we are seeking additional help to keep it in good working order. The ability to compile FG from source and some Windows batch scripting is a required skill. If you are willing and able to take up this role, please reach out to James Turner (mailing list), or get in touch via the forum 
FlightGear on Facebook
Since early December 2010, FlightGear has an official Facebook page. If you have a Facebook account please feel free to join the page.
FlightGear on Instagram
In January 2018 the @flightgear_sim Instagram account was brought back to life. If you've got nice screenshots to be featured, feel free to .
FlightGear on FlightSim.com
FlightGear has also a sub-forum on flightsim.com - just like the commercial flight sims. It is an opportunity to showcase what FG can do, get people curious and answer any questions they may have with regard to the software or the project.

If you want some graphic elements for your FlightGear-related site (such as a hangar or YouTube channel), please feel free to visit FlightGear logos for a repository of logos. And if you have some art skills, please don't hesitate to contribute with your own design creations.
The FlightGear project always needs screenshots, which show features that were added since the last release. These should be of good quality, especially in content and technical image properties. It is therefore recommended to use the best viable filter settings (anti-aliasing, texture sharpening, etc.). More info at Howto:Make nice screenshots.
Screenshot of the Month
If you want to participate in the screenshot contest, you can submit your candidate to the . Be sure to see the first post for participation rules. For purposes of convenience and organization, at the end of the month or after 20 entries have been submitted, a new forum topic will be started containing all shots in an easy-to-view layout. The voting will then take place there.
