Abstract
A head-up sight for an aircraft having a curved windshield. The windshield is external to the sight, which can project at infinity a symbology intended to be superimposed onto an external scene. The head-up sight includes a combination of optical elements bent at an angle to a folding mirror, the folding mirror having a curved shape adapted to correct the parallax associated with the optical power of the windshield. The head-up sight is especially applicable to aircraft having a cylindrical or conical windshield.
