AHRS Level adjust (Pitch and Roll)

If the AHRS is not aligned with the glider, then it has to
be adjusted.
Changes in pitch are caused by changes of aircraft mass
and changes of airspeed.
corresponds to one airspeed (indicated airspeed actually)
and one aircraft mass. When the glider flies faster or
slower, or if the glider is heavier or lighter, then the pitch
angle deviates from the reference.
