FlightGear Newsletter November 2020
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.
2020.3 LTS released
2020.3.x is a Long Term Stable release (LTS). Bug fixes will be backported, and the build maintained, for a much longer period than development preview builds.
Keflavik Airport (BIKF), in south-west Iceland, is the featured airport.
There is an additional development preview binary of the work-in-progress Compositor bundled with the LTS, like in the 2020.1 preview build.
OSM2City scenery for the whole of Iceland was built for the LTS earlier this year, but is not bundled due to the innosetup installer size limit. It is available from the OSM2City download list page.
The first version released on the flightgear.org website is labelled 2020.3.2. 2020.3.1 was a preliminary soft release to find bugs and installer issues.
For upcoming point releases of the 2020.3.x LTS, the current plan is to include some minor improvements like launcher UI tweaks, as well as bug fixes.
The road ahead
See Help wanted.
There are a lot of big infrastructure changes already nearly completed, well underway, and planned. These will be for the LTS after 2020.3.x.
With the LTS released, a lot of big changes have already been merged into the "next" branch:
- Compositor rendering framework - next has switched to the Compositor.
- World Scenery 3.0 (next generation scenery) initial deployment. WS 3.0 uses Virtual Planet Builder instead of terragear for terrain building.
- Composite Viewer - This allows Flightgear to have multiple top-level windows showing independent views of the scenery, and will also allow implementation of things like cockpit rear-view mirrors and cockpit displays of external views (tail cams, gear view etc). Screenshot
Some other big infrastructure changes being worked on, but not on next: replacement of the in-sim UI using Qt, infrastructure for regular world builds, runtime airport generation, move to a higher version of OpenGL (4.x is planned), OSM2City world build and OSM2City tech improvements etc.
If you are wondering when Flightgear will move to Vulkan using the newly released Vulkan Scene Graph (VSG) which is the successor to OSG that FG currently uses, VSG will be looked at after the current set of infrastructure and OpenGL 4.x according to plans mentioned by devs - as Vulkan Scene Graph hopefully should be mature and stable by then.
For those curious, keep and eye on the 'next' branch, or the nightly builds. The history of changes on 'next' can be viewed by clicking the "History" link for each repository on the sourceforge website: FlightGear , SimGear , FGData
The 'next' branch will build towards the next Development Preview release, and ultimately the next LTS. As always, nightly builds of the next branch are available at download.flightgear.org.
Photo texture support
Nathaniel Warner (nathaniel515) has submitted a patch to allow orthophoto textures to optionally be used and this is available in nightlies - see the forum thread. This works with current WS 2.0 scenery.
Updates to the FG homepage
Developers, there is a wiki draft page here to write a description of improvements since 2018.3 LTS to your craft or feature, with several accompanying screenshots.
James has said he is willing to review and update the homepage if material is submitted to the wiki, or otherwise handed over to him:
- James Turner  : If anyone wants to do an article on a particular aircraft or feature for the Website, that would be excellent: don’t be shy: if you can provide some text and a couple of screenshots, it can be turned into a post easily.
These will be published as news posts after 2020.3 LTS release, maybe about a week apart, or when material is available. If there is not enough material, several small items can be collected into a news post.
For screenshots, it's possible to pause the sim and turn up settings, if you normally have settings lower on an older laptop or similar - there may be suitable screenshots already submitted SOTM section in the forum under CC-BY-SA-4.0 that have not been uploaded to the wiki high settings screenshots category yet.
The most important things are the points about what to write, and some screenshots. Don't worry if wording or English is not perfect, it can be adjusted later. Knowledge of wiki syntax isn't needed for a simple draft, just click edit and type. URLs to screenshots can simply be pasted if you don't know how to upload, along with a note giving CC-BY-SA-4.0 permission.
Virtual FSWeekend Hackathon 2020 report
The Hacakthon was a success with a lot of contributors new to the project and contributors in non-core areas starting with core code and FGData contributions. See StuartB's writeup on the Hacakathon and lessons learned
Normally in mid-November a group of FlightGear enthusiasts participate in FSWeekend at Lelystad Airport in the Netherlands. Over the years this has been a focal point for both finishing existing development/releases and a catalyst for new ideas in FlightGear, as well as an opportunity for FlightGear enthusiasts to share a beer. FSWeekend 2020 was cancelled, so to keep the spirit alive, a Virtual FSWeekend Hackathon was held.
The current thought is to look at having a Hackathon every year, but at a different time to FSWeekend.
The hack projects/areas worked on were: CompositeViewer and Canvas, Controller-pilot data link communication (CPDLC), Feature Scaling, OSM2City Facades ), POH Checklists , Wake from AI Aircraft, WS3.0 Effects/Scenery
A substantial amount of the results from the Hacakathon are already merged on the next branch (and available on nightlies).
New software tools and projects
FGCom-Mumble aims to provide a mumble based FGCom implementation. This will simulate radio communications in a seamless frequency spectrum.
The project aims to be easy to use: Pilots just install the plugin, open mumble, join a channel on a mumble server and start using their radio stack in Flightgear.
The development is discussed in the . Releases can be downloaded from GitHub.
The project also has a flightgear wikipage: FGCom-mumble
Test server available!
I was able to get a small virtual linux server and deployed a test bed onto it.
- The address is mumble://fgcom.hallinger.org for mumble
- A status page can be viewed at http://fgcom.hallinger.org
I did already test this and i think it works fine. There is an outstanding issue with ATIS broadcasts stopping after a short while, but i currently think this is a library bug somewhere else.
To connect/use, you need to self-compile mumble; i wrote a small guide for debian/bullseye. Or you try the precompiled one: http://fgcom.hallinger.org/mumble-fgcom-test.tar.gz
Red Griffin ATC 2.0 released
Demo of a previous version of the ATC addon:
In the hangar
C172S with FG1000
The team are requesting thorough testing to find any needed tuning changes and missing elements.
The engine and systems work is already available, done, or will be completed shortly.
The team are placing a request/call for help with "exterior and interior cabin modeling" to make this a complete C172S.
Github repository and downloads:
The Airbus A320 family is available on the 2020.3 LTS release. This is a complete overhaul/replacement that has been worked on for many years by a team before releasing on LTS. It has the most detailed systems of glass cockpit airliners currently released in FGAddon, and a JSBSim FDM.
Eurocopter AS532 Cougar
Features: 90% Accurate FDM. 7 Configuration options, 15 Liveries. Multiplayer crew / Passenger function. ALS Glass and fuselage effects with livery specific reflection levels. Rotor wash on grass effects. Functional Winch man. Search and Recovery function for recovering other downed choppers over Multiplayer.
For more details, screenshots, and download see the forum thread.
- The Airspeed Indicator was reworked based on photos of a C182T and now corresponds to the real model.
- The Alternate static air system was modeled, and now the outer static ports can ice, causing the static port to be blocked. If this occurs, one can pull the red static air knob in the cockpit to switch the static system to a port inside the cabin. The Venturi effect will introduce some errors/misreadings, because cabin pressure is lower than the outside atmosphere based on speed. This was the last Cockpit item missing, so the Cockpit can be considered complete!
- Flap operation does consume electrical power now, which can be used in the preflight check to test the electrical system.
- Currently we have multiplayer enhancements in the works, involving a canvas redo for the registration number; and the damage system is nearly finished. Once we completed that, Heiko wants to do a FGAddon release.

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 Window 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 youtube
GinGin has re-created a space shuttle landing video of the Terminal Area Energy Management (TAEM) and Landing phases, overlayed with real voice communications between astronauts and mission control in the shuttle mission STS 155. The FlightGear's simulation of the space shuttle is the most detailed simulation outside NASA's internal ones, and has a JSBSim FDM backed by extensive windtunnel data.

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.
