Abstract (en)
[origin: US4792697A] The optical and electronic equipment normally carried by an aircraft pilot's helmet is carried by a support element which is placed at a distance from the helmet and accordingly relieves the load on the pilot's head. The support element is maintained in a predetermined position location with respect to the helmet by means of a detection assembly, a computer for determining errors in positioning, a control circuit which generates signals corresponding to these errors, and a set of jacks controlled by the error signals for modifying the position of the support element with respect to the aircraft structure and cancelling the positioning errors.
