ABSTRACT:
A glide path instrument for an aircraft to display to a pilot that the aircraft is descending on a predetermined inclined glide path. The instrument includes a rectangular casing mountable in stationary position in the aircraft and carrying a freely pivotable frame which has sighting elements at opposite ends spaced different vertical distances from the plane of the frame. The frame carries a pendulum-like structure including depending legs supporting free swinging weights. The sighting elements align in a single sight plane with a runway reference point when the aircraft is at the predetermined glide angle. A lamp in the casing illuminates the sighting elements.
