[Flightgear-devel] lightning tacan

[<csa...@gm...>]

Hello!

Nick had some trouble with the tacan on the lightning, so I had a peek at it.
Worked for me all right. However, the instrument needle works as if it
were a fixed compass card indicator, which it isn't. So there should
be an additional rotation applied to adjust for the a/c heading. Patch
attached.

Please check before commit. Pretty please? ;)

I also have some issues:
1) The lightning even has an ILS instrument but I could not find a
DME. Have I overlooked it?
2) How do you check if the tacan/vor/adf/whatever radio transmitter is
in range? A digital display could go blank, but an instrument needle
must point somewhere. Shouldn't there be an indicator light or
something? Or is it just left to the pilot to listen for the morse
code?
3) In the lightning rmi and hsi animations there are a couple of
interpolation tables for identity transformation. Do they have any
purpose?

Greets,
Csaba
