P-47D almost ready

The P-47D model is almost ready for release. Version number is now 0.9, and the model is complete except for some handling tweaks, especially ground handling, and a couple CAD and texture adjustments. This is a former AlphaSim model, and now wears the livery of Colonel Bud Mahurin's mount when he was with the 56th Fighter Group in 1943/44. The model has a semi-transparent bit of forward window frame to aid in seeing the runway on landing.

The Bone Yard

Is there anybody reading this who has write permissions to the FlightGear wiki? I've noticed that Kent Esbenshade's hangar, The Bone Yard (link can be found on this page), is not listed among the third party hangars. I think a lot of people might be missing out on Kent's great models.

AH-1 and newest FG snapshot

Does anyone know if the AH-1 Cobra model from the hangar works with the latest snapshot release of FlightGear?

DavePack update

The sounds used by the Super Tucano models (the AT-29 and A-29B) are now in DavePack, and the DavePack version number for FG 2.2 is now 4.8. Both Super Tucano models are also updated. Every released model now has a FG2.2 update. I never thought this day would arrive!

BAK-12 barrier

The BAK-12 model is now updated for FG2.2, although it might also work in FG2.0 or older. The package contains an example AI scenario file that you can use to add two barriers to runway 21R/03L at Nellis AFB. Just place the scenario file in your AI directory, and invoke the scenario file in your preferences.xml file. There is also a readme file included which explains all this.

Crash-detect System

Most of the models in the Hangar use a "crash detect" system, which monitors height and g-load, and freezes the FDM when parameters are exceeded. Usually I set the limits to -1 foot and 9 g's. While adapting all the models to FG 2.2 standard lately, I noticed that many of them were failing to ground trim properly at start-up. The models flew fine thereafter, and you wouldn't have noticed this unless you routinely run FG with a console window open in order to observe the warning output. Thomas Kreitler discovered that the default FDM integration algorithm ("Trapezoidal") was causing this, and switching to another algorithm, "Adams Bashforth 2", fixed it. I'm now changing all crash detect system files to set "Adams Bashforth 2" as a default.
