Re: [Flightgear-devel] turbine inlet temperature in the seneca (TIT)

[Tuomas K. <tuo...@gm...>]

Ok, I made a pretty gross hack for now, and used EGT but made the
gauge show 100°F higher :-P

On the other hand, since I am making a custom panel for the senecaII
anyway, I could just make the gauges EGT for now, as they serve more
or less the same purpose in engine management anyway.

Torsten, you seem to be the maintainer for the SenecaII, would you be
interested in including the gauges in the seneca at some point? Could
make another nice fullscreen minipanel, since the small engine gauge
cluster fits nicely in a monitor with the basic "sixpack"..

If yes, how would we proceed? And if yes, should they go in
Aircraft/Instruments/ or into the SenecaII folder?

I could also do some textures for the Seneca instrument panel, if that
is a welcome idea? I have some panel photos I took a while ago that
could be useful there..
