Development news
Important FGRun memory fix
FGRun used to keep all loaded aircraft (in one session) in cache for quick re-view on the aircraft selection page. There were cases reported in which the memory usage reached 1GB; slowing down the entire computer tremendously! Since FGRun must stay open during your FlightGear flights, it decreased in-sim framerates. With the fix, FGRun only uses necessary resources.
Experimental: texture mapped line data
I've created a local experimental branch for allowing Terragear to texture map roads, streams, and coastlines. It is in the very early stages, but is starting to show promise. While the Terragear team's priorities are to optimize and import highly detailed land-class imagery, I thought it would be a good idea to enhance existing polygons as well.
I'm keeping status updates here: TerraGear texmapped line data
JSBSim: Arbitrary Functions in Engine (and other) Models
JSBSim now has the ability to have functions embedded in engine configurations. These functions look the same as the main configuration functions and can run before (pre) or after (post) the main code. They are handy for keeping engine controlling functions organized with the engines they're supposed to be controlling. There is also a wild-card available in the property tag, like this: <p>propulsion/engine[#]/thrust-lbs</p>
JSBSim: Experimental Rotor Model
Thomas Kreitler created a rotor model in JSBSim, so its now possible to model helicopters in that FDM, too. His first experimental helicopter is the AH-1S. This model isn't in FlightGear's GIT, yet, but you can find it in JSBSim stand-alone if you'd like to experiment with it.
JSBSim: Cooling Support for Piston Engine Model
JSBSim's piston engine model took another step forward in realism by exposing properties to control engine cooling.
JSBSim: NaN Fixes
Nasal for newbies
New software tools and projects
3D Modeling With Perl
Curt Olson recently leveraged the perl scripting language and a simple spline module to generate a 3d model of a UAV design that would have been hard to model with more traditional approaches Details and pictures can be found at Curt's blog.
FlightGear addons and mods
In the hangar
Generic Boeing CDU
Gijs commited a generic - Boeing style - Control Display Unit (CDU) to Git. The CDU comes with two textures: a brown one (as seen on the 747) or a grey one (737). The number of simulated pages is growing rapidly and currently include at least:
- one route setup (interconnected to the well-known FlightGear route manager), from departure via waypoints to arrival airports.
- various performance data, like takeoff speeds (V1, Vr, V2) and weights.
A wiki article has been set up to explain aircraft developers how to implement the CDU in their aircraft.
New aircraft
ATR 72-500
Skyop has started his latest aircraft project, the ATR 72-500. This turboprop airliner currently features a lighting system, an engine control system (autostart), pushback, and livery over MP. A 3d cockpit will follow in the upcoming months.
DC-9-32
A group of developers have started developing the DC-9 with the kind help of Buckaroo. Currently, the aircraft still requires animations and some adjustments to the autopilot. However, the cockpit and other parts are almost complete.
Spitfire Vb
A new version of the Spitfire has been added to the hanger. The Spitfire V, although a stopgap version, became the second most numerous variant to be produced. It was widely exported to foreign airforces both during and after WWII. The version modelled here is the B version with 2 20mm cannon and 4 .303 machine guns. The cannon ammunition was carried in drums, limiting the supply to 60 rounds per gun, and necessitating blisters on top and underneath the wing. The particular aircraft depicted is preserved, and is still flying today. You can see a walkround here: [2]
Sukhoi T-50 PAK-FA
Ummon and pjedvaj have started the PAK-FA project. The PAK FA, also known as the T-50, is a fifth generation jet fighter prototype developed by Sukhoi OKB in Russia. It is scheduled to enter service by 2014. The Flightgear version features a new high-poly model and set of animations, along with three liveries. The FDM has been redone in JSBSim and features thrust vectoring control and fly by wire stability augmentation. Cockpit instruments are not modeled yet.
Updated aircraft
LZ 121 Nordstern
The Zeppelin LZ 121 Nordstern has been updated with a new variometer and control car windows and some other details by Anders.
Liveries
Scenery corner
This month, we reached 2000 unique models in the scenery database! Currently there are 2023 models in the database. Help us get to 3000 even faster... Please contribute a scenery model today.
Scenery Models
The highest tower in the world, the Burj Khalifa, former known as the Burj Dubai, has been added to the database. Landmarks have also been added to Lyon, France. Finally, skyscrapers for both Montreal (Place Ville Marie) and Vancouver (One Wall Centre) in Canada have been added.
New York City
A collaborative effort has been launched to model as many skyscrapers and landmarks of New York City as possible. This month, the following New York buildings were contributed, by several different people:
- Empire State Building
- Statue of Liberty
- UN Headquarters Building
- Citigroup Building
- MetLife Building
- GM Building
- Verizon Building
- Penn Plaza and Madison Square Garden
We still would like as many custom buildings as possible in this area! If you are interested in contributing to the New York City scenery project, please visit the forum.
Eastern Asia
Many buildings in Eastern Asia were added to the database this month, including:
- Akashi Kaikyo bridge (Kobe, Japan)
- Ruygyong Hotel (Pyongyang, North Korea)
- Bank of China (Hong Kong, China)
- CCTV Headquarters (Beijing, China)
- Bitexco Financial Tower (Ho Chi Minh City, Vietnam)
- Petronas Towers (Kuala Lumpur, Malaysia)
- Saigon Trade Center (Ho Chi Minh City, Vietnam)
If you would like to fly near them you can use TerraSync or download an updated objects file from http://scenemodels.flightgear.org.
Airports
Charlottesville Albemarle Airport (KCHO)
I admit that I've taken a couple of weeks off, but I have made some significan progress since December. I have made the rain canopy (or whatever it's called) almost completely accurate, I've made the building more realistic (height-wise), and I've added the cylinder part of the airport. My goals to get to by February are completing the doors, add-in the second waiting room (external of course), and add the windows to the cylinder.
Samedan Engiadina Airport (LSZS)
Eventually the Engiadina Airport LSZS, close to Sankt Moritz (Sant Murezzan, in Ladin), is available on Terrasync. You may reach it comfortably from LOWI Innsbruck following upstream the Enn River (Engiadina); after the flight you may have a Calanda Beer at the cafeteria aside of Terminal C.
The building have been done with the contribution of HHS, who provided the untextured blend files, and ot-666, who gave precious hints. F-SIG took the screenshot. For those not using Terrasync the files (including the .stg file) are available for download at http://digilander.libero.it/scighera_fg

Suggested flights
Princess Juliana International Airport (TNCM) at the isle of Saint Martin, is one of the most popular airports in FlightGear. In large part due to the custom objects and land cover. However, St. Maarten is only one of several detailed airports in the region - and, while the approach for TNCM is one of the most memorable in the whole world, the land cover for St. Kitts and Nevis makes it a lovely place to fly.
British Airways, US Airways and American Airlines, among others, all fly into St. Kitts' Robert L. Bradshaw International Airport (TKPK) in real life.
Take off from TKPK in a Piper Cub and make a northward, clockwise circle of the island. Start your descent on the east side of the island, and focus on the small hill which separates the north from the south. Start hugging the coast near the beach and look to the west - as soon as the railroad heads to the southwest, you're about ready to turn for final. Make your right hand turn for final and taxi to the terminal.
If you want to fully explore this whole country, take off in a Beaver, which has a little more speed, and fly a figure eight. Take off from TKPK and circle the airport to the north like in the Cub. Then instead of landing, perform a touch-and-go and turn left over the boat terminal and make for the west coast of Nevis. Enjoy the beauty of the south coast of St. Kitts before circling Nevis. Over Nevis, you have several options - cut your flight short and land at TKPN on the island of Nevis, complete the "figure eight" by heading back to TKPK, or check your fuel and head east across the Caribbean to Antigua (which does not have custom land cover).

FlightGear on Facebook
Since early December, FlightGear has an official Facebook page. Four weeks after its creation, over 1000 people "liked it". Please join our page, if you have a Facebook account.
FlightGear on YouTube
- There are a few places in FlightGear that can be overlayed with photo-textures. One of those is the Brest area, featured in a VFR flight in the C172.
- Albicop simulated the Hudson River Landing in FlightGear. Altough the New York scenery is far from accurate (it is being worked at, as you can read elsewhere in this newsletter), the video is quite a good resamblance with the actual flight.
- HHS and ot-666 continuesly improve the LOJO heliport, showcased in a video featuring the moveable helipads.
- Active road vehicles are something FlightGear lacks compared to other sims. Luckily there are people trying various methods to implement traffic. One of them is Tuxklok, who placed some nice traffic near Insbruck, Germany. Defenitely something we'll hear more off in the future!
New tutorials and screencasts

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 mis-conception 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.

Reminder: Google's Summer of Code 2011
We would like to remind all readers that the 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.
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.
