Okay, here's what I've got so far:
GIT Autopilot: This is mostly functional, only a few little niggles for me to fix. It features:
Standard Modes: Magnetic Heading Hold, True Heading Hold, Altitude Hold, Speed hold (with/without reheat)
Navigation Modes: GPS/Gallileo Hold, TACAN Hold, NAV1 Hold
No advanced modes yet - I can't really start those until I've got V2.0's autopilot, which is going to be a bit of a headache, but I hope to finish it very soon.
There is a dedicated Typhoon Autopilot dialog box available in the Autopilot Menu - again, this is mostly functional with just a couple of buttons not working.
ULP Buttons: We don't know what it's actually called, but we call it the Upper Left Panel, or ULP. I have experimented with the bindings quite a lot and I think this one is the most realistic. There are more modes that there are buttons/indicators, but I like it. Remember to make a copy of cockpit.xml (called cockpit-old.xml or something) in case you want to switch back to Almursi's bindings, which is less reliant on the autopilot dialog box but, in my opinion, is not quite as informative.
I mentioned it before, but I quite like the idea of having modular additions to the aircraft, just like in real life (different customers specify different systems). Aircraft releases are made with defaults, but you can download modules like this one from hangars, just as you'd download complete aircraft, and simply slot them in. This allows you to customise your Eurofighter so as to best suit your flying style, view setups etc. Please let me know how you get on.
You click an autopilot button to select that mode, and click again to deselect. Clicking another mode will deselect the current mode and select the new one. Clicking AP will cancel all vertical and lateral modes, and clicking AT enables/disables the Autothrottle. Modes available at present are:
HDG - Magnetic Heading Hold
TRK - True Heading/GPS hold
ALT - Altitude Hold
TFR - Terrain Following Radar hold
NIS - TACAN Hold (wrongly labelled at the moment)
NAV - NAV1 Hold
More to follow!! Please note that nothing here has been polished, it's a test release so you guys can (hopefully) provide some feedback. We know the FDM is still pilot-crushingly agile, my next job after the autopilot is sorted is to develop the Flight Control System which will reign in it, but at the moment, I do not anticipate this working with V2.0 so it will probably not be released until the new FG version is right, around New Year.
