The Stabilized Glide Path Indicator, IVERA Model 650 is an equipment designed to provide helicopter pilots, especially in the final phase of landing on ship's flight deck, stabilized visual glide path indication, in order to make possible day and night landing in any condition of visibility.

This visual indication is done by means of a high precision optical device, which projects in the space a luminous cone divided into three colorful beams: red, green and amber.

The axis of the projected cone corresponds to the axis of the ideal approach path for the landing. The variation of the aircraft altitude in relation to this axis is indicated visually within the limits of one of the three colors: red, below the ideal approach path; amber, above the approach path and green, on the correct approach path for landing.
