AutoTrimMFD adjusts elevator trim automatically so as to prevent the pitch from changing. Designed for keyboard flying, for those too lazy to set the trim manually (like me). The trim is only adjusted while the elevator is neutral, so you need to let go of the elevator and wait a couple of seconds to let it do the work.
Additionally, this addon can optionally assist the elevator with the trim by moving it in the same direction as requested by the pilot. On DeltaGlider this can increase the maximum pitch rate.
Both features are off by default, and can be enabled independently via the MFD.
Known issues:
[*]
The autopilot is very basic. It's not as fast as it could be, and is known to cause long-period oscillations in the upper atmosphere.
[*]
Tuned specifically for the DeltaGlider in the 2010 beta. Tested to work with DGIV. The tuning seems a bit off for the DeltaGlider of Orbiter 2006.
[*]
The tuning is not tweakable.
[*]
Will always start in the "off" state, regardless of the state when the scenario was saved.
