Definitely problems in aar.nas, seaport.nas; as these were hanging off a fdm-initialized.
The others have timers that are started from a listener and as such are more suited to use maketimer rather than settimer
The modules that use the loopid technique are probably fine, but these are also more suited (and easier to understand) using a maketimer
aar.nas disables $FG_ROOT/Nasal/fuel.nas' main loop, as it should be able
to fully replace it. Ideally, there would be no aar.nas at all, and fuel.nas
would do the job for YASim & JSBSim. Unfortunately, there's a problem with
fuel.nas that's not easy to fix ...
far as this supports air refueling at all)
- make listeners keep variables up-to-date (for better performance)
- remove the ugly initialization stuff in the main loop, but wait in
an extra loop for the FDM to come up
This script works now with the a4f, too. The vulcan2 is *supposed* to
work, but there's apparently a bug in it that prevents it.
/systems/refuel/contact is correcly set, and that should be enough for it.
