Hi Ian,
If you wish to set your own tower position, it's pretty straight forward
and can be done manually or via nasal or probably a few other mechanisms.
By default flightgear will set the tower position to the nearest airfield,
so to disable that, set: /sim/tower/auto-position = 0
Then you can set /sim/tower/longitude-deg, /sim/tower/latitude-deg,
and /sim/tower/altitude-ft
In one of my small experiments I wrote a little nasal snippet to set the
tower position to my ideal/target landing spot on the deck of the Carl
Vinson, then I forced the camera to look up 3.5 degrees (right up the glide
slope) and pointed it at the ideal approach heading. Then I could watch
the aircraft approach the carrier from a fixed camera position on the
carrier deck -- and if the approach is perfect, the aircraft will be
exactly in the center of the screen. It's actually fun to watch this view
in heavy turbulence or a cross wind.
For RC views, you may also wish to play around with auto-zooming -- either
to help keep the aircraft large enough to see, or help keep the horizon in
view -- either can be useful at times with RC flying.
Best regards,
Curt.

Virtualization & Cloud Management Using Capacity Planning
Cloud computing makes use of virtualization - but cloud computing
also focuses on allowing computing to be delivered as a service.
