There is an entry in SenecaII-jsbsim.xml controlling pitch due to flaps.
I changed the signs and it pitches up, but way too much.

So the TAS dial is manually operated then?

Yep - the flap behaviour is crap - I'm working on an improved FDM config. Have 
to get deeper in my old aerodynamics books for that...

Thats how it works in reality.  You look on your outside air temperature 
indicator (will be there in the next version) and your altimeter, place your 
pressure altitude above the oat on the white TAS-dial and the needle points 
to your TAS.

The latest version on my web site already has a working TAS-dial.

Greetings, Torsten

Yes, there is an object in the airspeed indicator model and the texture is 
complete. I will give it a blister and a hotspot to turn it. Should be ready 
soon.

Looks great, flies good.  I managed some pretty landings after I got a
feel for it.  Is it supposed to pitch down so violently when the flaps
deploy, though?

The instrument panel is outstanding, does (will) the white dial on the
airspeed indicator move to give KCAS or TAS?

This document may be helpful in the flight model, being about the Seneca
itself, or a similar type:

.net/2060/19770026160&oaiID=oai:casi.ntrs.nasa.gov:19770026160

Go to http://ntrs.nasa.gov and do a search on "light twin" and see what
else you get back.

[Flightgear-devel] A SenecaII for FlightGear: first version available

2006-04-24 Thread Torsten Dreyer
Hi all,

it's been a while, since I announced the model for a Seneca. It is a *LOT* 
more work, than I expected it to be so it took a lot longer than I thought. 
But I think I can show you what I have so far:

http://www.t3r.de/fg/seneca/

The site gives you a something to look at and a downloadable version.
This should be considered a before-pre-alpha-preview release with lots of 
work-in-progress and under-construction items. But there is also a lot to see 
already.
If anybody wants to give it a try, I whould be happy to get some comments.

Greetings, Torsten
