Autopilot - err, not that I can find ;-) Not expecting one, its a military trainer. GPS - no to that also. IRIS say they have modelled the systems using all the info that is available and with input from current/ex military pilots. Certainly the nav side of things seems to have had some input during the beta phase according to the update release notes. Makes navigation more fun tho - no autopilot is hardly a chore as it flies nicely and plan your route with navaids before you go (the way it used to be done!). The only popup available controls external tanks, chocks and both pilots, you can also control fuel load from it. The radios have a preset frequency mode and these presets can be edited in the configuration manager so you can set them for any airspace/ airbase you want. Of course you could add a popup GPS but no route would be displayed in cockpit. I am thinking about doing this to save peeping at the map...
There do not appear to be any motion effects included (I am using accufeel anyway) - wonder if the swaying you saw was from a playback? I have noticed the same happening when I playback landings from the VC on several addons.
