Hi Necolatis,
Last night I saw the JA37 is at version 3.027, not yet downloaded (I will download when I get my house), I'll see if today I have time to fly a little with the new version.
Here was my landing a few days ago in SBPA. :D

Yeah, there is a new version. JazzTp helped with some remodelling of cockpit in version 3.027. :)

I have uploaded a new version, it contains an important hotfix for canopy animation.

The feature-list has also been updated: http://nikolaivchr.github.io/flightgear-saab-ja-37-viggen/

Note that for the new incoming warning to work, the person firing against you must have MP messages enabled and also fly in a Viggen version 3.028+ or an f-14b or m2000-5.

Changelog:
Model: Right attitude indicator has been made more flat.
Model: Added 2 handles to cockpit front panel.
Model: Made the 3 indicators on the left on frontpanel look more like the real Viggens.
Sim: Created a JSB fuel system. It runs on pneumatics, hydraulics and electricity.
Sim: Made failure modes for fuel flow distributor, electric fuel pumps and pneumatics.
Model: Updated left indicator panel to respond to failures in fuel system.
Effect: The ALS afterburner effect will now be less evident in bright light.
Effect: The non-ALS afterburner effect now uses scene diffuse color to determine translucency instead of sun position.
Sim: Replay recorder no longer records afterburner flame intensity, that depends now of scene brightness at the time of replay.
Sim: Droptank now requires DC voltage and masterarm off to be jettisoned.
Sim: When firing air2air missile, a message will now be shown. Also in MP if enabled.
Sound: Annunciator will now warn of incoming guided air2air missile from ja37, m2000-5 or f-14b. It will also say from which direction.
Sim: Exterior light control is now split into 4 switches instead of just 2; landing, beacon, navigation and anti collision.
Effect: Installed contrail and persistent contrail effect.
Model: Added a knob for HUD brightness.
Model: Made the oxygen manometer show the bottle pressure, not the mask pressure.
Animation: Fixed that gauge glasses would be rotated when canopy was opened.
GUI: Added mask oxygen pressure to systems monitor.

A new version (3.100) has been released and can be downloaded from the hangar.

Major changes:
JazzTp has overhauled the cockpit layout, and modeled switches, knobs and throttle.
Many other updates to model, fdm, systems and cockpit. The changelog for this release is 95 lines long, so too much to list here.

I'm getting the following error message on launching this new version:

"not well-formed (invalid token)
at k:/Flightgear 3.4.0/data/Aircraft/JA37/Engines/RMiB.xml, line 37, column 6

received from SimGear XML Parser"

then FG crashes.

I see the same 'SimGear XML Parser' crash with the current git repositories. Reverting to the previous version (r802) fixes the problem.

Regards,

Edward


EDIT: The problem is a number of disallowed '--' double characters in the new XML comment in the JA37/Engines/RM8B.xml file.

Ok, where are those "--" found? I suppose just deleting or changing the number would fix it, right?

Look in the JA37/Engines/RM8B.xml file. You'll see the new comment:

If you delete this entire comment, it will work. The problem are the subsections with '----' underlines, as the double '--' character is not allowed in XML comments.

I downloaded on Thursday or Friday to version 3.029 (not 3.010 version) and will not appear any error message on the console, it's ok without problems.

(I did a manual delete and it launches fine now.)

Is it just me or does it accelerate somewhat slower now?

Which version are you comparing to?

And also notice that there is now much more fuel loaded per default.
