For the cockpit view, it might be interested to add optional
acceleration effects to make up for the lack of full motion -- I think
I first noticed this trick in Battle of Britain. The FDMs already
publish the required information in the property tree:

/accelerations/pilot/x-accel-fps_sec
/accelerations/pilot/y-accel-fps_sec
/accelerations/pilot/z-accel-fps_sec

What we'd do is tilt the cockpit viewpoint slightly for any strong
forwards/backwards or sideways accelerations. For example, a strong,
forward acceleration (like a takeoff roll in a fighter jet) might tilt
the view pitch angle up a degree or so, while a strong deceleration

I think this is a great idea. You might try treating the pilot eyepoint as a spring/mass/damper system in the XY plane and assume no Z motion.
