Perhaps I can explain...
It's all Lawrie's fault!
See he comes up with an airport that doesn't exist in the FS world, and then starts the hand-wringing thing about how there's no AI traffic there
(Doh...it doesn't exist, how could GNZLAP go there??)
But he's very persuasive, and can bring tears to your eyes when he gets in his stride.
OK, so what to do?
Let me explain a little about the GNZLAP project.
Being reality-based, it was important to do the aircraft dispersion correctly, across NZ.
We have covered maybe 12% of the GA fleet, so at each airport you try to get that proportion of the resident population.
That way you maintain the "feel" of the AI consistently.
If you now add an airport that was not there before, the AI have to go somewhere.
Wanganui? Nope, already has more than its fair share.
Palmy? And then some, in spades.
NZPP? GNZLAP appears to live there.
ANd so on.
Jabiru's are microlights, and so they aren't actually GNZLAP material at all.
Solution: a fake waypoint, as you point out Bazza, due west.
They fly out and disappear, respawn later, and come back.
This way they only use up NZFP real estate, and don't unbalance the surrounding airports.
If you fly with them, they will indeed just keep going, as they need to cross your visibility horizon to vanish.
As to the startling performance...
Bill's model was like mannah from heaven, readymade for this little project.
One problem: when converted for AI use, they preferred to taxi all the way to their destination, and never took off!
This happens occasionally with flyable models.
In the end (and I do mean, the end, after a
lot of other options) they got a stock C182 underpinning, and so may be a little brisker than the real thing.
Cut us a little slack here willya, they are imaginary little planes after all.
Having said all of this, in the end I weakened, and the Maule and Cessna that appear at Foxpine are indeed on the CAA register, are now part of GNZLAP, and do fly up and down to Wanganui.
Just couldn't resist
great work Lawrie and Charl
