Corrected throttle stick exponentional function in AH mode
Changed AH to work with absolute instead of relative altitude
Removed obsolete (unused) code
Missing "
Scale up desired throttle in AH mode to compensate for roll/pitch
Initialize altitude before switching to "running". Not doing this could
cause glitches during the very first switch to AH.
Scale down initial throttle when AH is engaged based on roll/pitch angle.
This improves AH behaviour when switching to AH while being in fast
forward flight.
OP-1022: Added a velocity loop in AH module, used when throttle is not in central position.
OP-1022: replace old KF in alitude hold with status from filters
OP-1022: replace old KF in alitude hold with status from filters
OP-1022 Fix problem with EventSystem due to too high update rate
OP-1022 Adding a proportional term on the square of the altitude error.
OP-1022 Uncrustify
Added vertical velocity as a control loop input to improve dynamics during
commanded ascend/decent.
