Stricter JSBSIM tag checking

Cquote1.png Hi all,

since the change to the parser, JSBSim is not only a lot more verbose about issues (good!) but also a lot more picky about accepting syntactically bad tags (somewhat problematic).

The implication is that this is again a change that will render aircraft which previously worked okay non-functional on next - so an unknown fraction of our JSBSim fleet currently won't start.

(And yes, I've seen issues in someone else's code, so it's not only my sloppy habits ;-) )

The good news is that we get explicit locations for the offending tags including line numbers, so generally the issues are easy to fix. Also, these are tags which never worked as intended in the first place, so fixing them to a working condition is likely easy.

My recommendation is that anyone who sees such issues on the repo simply goes ahead and pushes a fix if he has commit rights. If not, or if you feel unsure because you have no experience with JSBSim, give me a note with the errors and I'll go ahead and do the maintenance.

New software tools and projects

FaceTrackNoIR Support ported

FlightGear was one of the first programs which had been supported by FaceTrackNoIR, a headtracking program which registered the movements of the head by a webcam, no additional hardware (eg. markers) are required. With the switch using FGAddon the support was lost for a time. HHS now ported it now into the new scheme. More information about and how to use it you can find here: http://wiki.flightgear.org/FaceTrackNoIR

In the hangar

New aircraft

Robin DR401 155CDI

iamzac created a Robin DR401 155CDI using the FG1000 panel by Stuart. This aircraft has sound improvements and bugfixes, new ALS effects, and improvements to the 3D model. By default it starts with the existing classic cockpit and FG1000 is not loaded or initialized for maximum performance, once you toggle it from he menu or by pressing "g" it's loaded and initialized the first time, and if you toggle it again it remains loaded and running in the background even if it's hidden. The FG1000 is completely vanilla and it's loaded from flightgear's folders so any improvement in the future of the instrument with flightgear will be used automatically. You need FlightGear 2018.3.1 RC or newer to use it - the download is at https://www.dropbox.com/s/nbon8klpes3g9s0/DR400-dauphinR1.zip?dl=0.

Updated aircraft

Citation II

The Cessna 550 Citation II was once again updated, with the addition of external power which can be toggled from the menu. The reversers can now only be stowed if the throttle is at idle, and the throttle behaviour with joysticks was improved. Furthermore, a new key, Ctrl + O, was added, which toggles the cutoffs. Finally, the state system received a few bugfixes, correcting the fuel boost pump states. These updates are available from FGAddon or through the launcher.


A long standing bug in the 777 has been corrected, where the views would be broken after adjusting minimums. Furthermore, the checklists have been updated to better match the real aircraft's procedures. The IDENT button on the transponder is now functional, and the transponder now transmits information over multiplayer. These updates are available from FGAddon or through the launcher.

Lockheed 1049h

Lbrenta released version 3.03 of the Lockheed 1049h, implementing more realistic engines with better supercharger parameters, volumetric efficiency, and bsfc. Furthermore, a debugging tool to compute endurance and range was added, which can be seen at the following properties:




Aeromexico 767-300

The Aeromexico skyteam livery on liveries.flightgear.org was correcting, removing an accented character in the xml file which broke the aircraft.


The AI team makes FlightGear more realistic, colorful and lively every month. You can support the important development of Interactive Traffic and contribute at the FlightGear AI forums.

Scenery corner



OSM2City is now available along with legoboyvdlp's Ireland-fg-CustomScenery: https://github.com/legoboyvdlp/Ireland-fg-CustomScenery. This osm2city covers all of Northern Ireland. It is quite heavy on performance, but looks very good - thanks to Vanosten and the other osm2city developers!

FlightGear logos

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

FlightGear's Screenshot of the Month November 2018 is Moonset over Antartica from 3000 miles elevation by eatdirt: Moonset over Antartica from 3000 miles elevation by eatdirt

If you want to participate in the screenshot contest , you can submit your candidate to this forum topic. Be sure to see the first post for participation rules. For purposes of convenience and organization, after all the 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. Once the voting has finished, the best screenshot will be presented in the Newsletter.

Thanks for reading FlightGear Newsletter November 2018!
