ABSTRACT:
An automatic level device for sensing the height and pitch of an aircraft and for adjusting a loader platform to align with the aircraft. An umbilical cord connected between the platform and the aircraft includes a tube partially filled with mercury and having a plurality of electrodes spaced along one end of the tube. As the height of the aircraft changes the mercury contacts a different number of electrodes and the electrodes provide signals for adjusting the level of the platform and aligning the platform with the aircraft.
