I'm not getting segfaults here, but I do see that the AI objects are not
binding to properties properly. When I have one sailboat and two airplanes
running I see an AI count of 3, bu

Murphy's law! That's a hazard by itself. We definately can't leave this out!
Some other hazards included:
Birds damaging airframe.
Engine explosions.
Birds get into engines.
Engine disintegrating.
Engine failures.
Hydraulics failures.
Electric problems such as short circuit leading to hazard suc

The key words being "in dives". The solver values are specified in
level flight. And dives can

Add to that a set of ground conditions:
Ice on ground, wet ground, etc.

Hi,
We desperately need new splash screens and website snapshots. Esp. the
snapshots are hopelessly out of sync.
Any volunteer?

1) The state/existance of the hazard. Do icing conditions exist? At
what altitudes, severity, etc. etc. This should probably live in the
environment subsystem.
As far as I recall, icing is most likely between about 0 degC and -10 degC,
and is very rare below -20 degC or

What other potential hazards did you have in mind?
Structural damage, fire, obstructed visibility (say, ice on the windshielf)
and depressurization spring immediately to mind.

Andy has once posted a method to create instrument scales using Perl to
output PostScript commands. While I like Perl, I'm not good at PS, so I
tried an alternate approach: MetaPost.
MetaPost is a spin-off of MetaFont, which was designed to create the fonts
for TeX. Is comes with typical TeX insta

You might want to make that a number, specifying a normalized

I don't want to over engineer an ultimate solution right now, I just
