Hi Curt,
While "/ai/models/carrier/controls/ai-control = true" the Nimitz patrols
within the box defined in AI/nimitz_demo.xml. You can turn the carrier into
wind for launch or recovery by using the menu item AI ->AI Carrier Options
or which will turn the carrier until the relative wind is either axial or
down the angle. Alternatively, in the property browser you can set
ai-control = false and then set tgt-heading-degs to whatever you want.
Setting ai-control back to true will cause the carrier to head back into its
patrol area, and once there to resume its patrol.

Hi Vivian,
Thanks for confirming those numbers. I have one more question for you. I
am playing around with the "nimitz_demo" ai scenario.
I see that the carrier is turning, rather than following a fixed course.
/ai/models/carrier/controls/in-to-wind = false
/ai/models/carrier/controls/base-course-deg = 200
turn-to-base-course = true
turn-to-launch-hdg = false
But I see that /ai/models/carrier/controls/tgt-heading-degs is slowly
increasing and the orientation is slowly chasing that.
Is the carrier trying to follow some predefined path? Is there a way to
force it to travel straight?
I hear your advice about flying the ball, but I'm trying to rig a specific
demo for someone and a turning carrier is confusing my script. :-)
Thanks,
Curt.

Hi Curt,
Yes the centerline offset for the Nimitz/FLOLS is 8 deg, and the optimum
glideslope is 3.5. The FLOLS visible glideslope arc is 1.7 deg.
If you fly the ball you should hit # 3 wire.
I got that from a reference I have here.
Vivian.

Hi Jan,
Thanks for your reply. What I'm wondering though is for the FlightGear
Nimitz, what glide slope approach path puts me in the sweet spot of the
FLOLS?
And for whatever it's worth, visually it appears that the landing deck is
offset closer to 8 degrees. That lines me up a lot better than 9 degrees.
But I'd love to know the exact angle for the FlightGear Nimitz model so I
don't have to fudge things and guess.
Thanks!
Curt.
