ABSTRACT:
The self-retracting sighting device for an onboard optoelectronic localization and identification system has an elongated shape such that its rotation axis in elevation, beneath the fuselage of the carrier, is off-centered with respect to the input pupil. For the bottom line of sight, the device protrudes out of the fuselage to a major extent but, when the elevation angle increases, the device self-retracts beneath the fuselage, the top lines of sight being obtained without hindrance to the pilot's visibility. By additional rotation about the elevation axis, the input pupil is completely retracted beneath the fuselage, that part of the sighting device that protrudes out of the fuselage being then at its minimum and having an aerodynamic shape. The device can be applied notably to carriers in which the pilot's visibility is essential, for example during the stages of touchdown on aircraft carriers.
