Zusammenfassung:The present invention relates primarily to an aircraft approach and landing system using passive retroreflective panels strategically placed along both sides of a landing strip or runway. The retroreflective panels comprise pairs of color-coded orange panel markers indicating the touchdown zone and singly, the remainder of the landing strip. The array of reflective elements are placed adjacent to the runway path so that the array produces a left/right reflected beam envelope within which an aircraft may be centered in order to maintain a desired landing vector. Upon installation of the reflector panel elements, each panel can be tilted with respect to the runway surface at an angle corresponding to the glide slope to produce a visual reflective beam aligned to the desired glide slope angle. The retroreflective sheeting of the preferred embodiment will provide a highly visible fluorescent component, where these panels will render suitable and effective utility in daytime operation, as well as, in nighttime use. The strategic placement dual sided panels along both sides of a landing strip, symmetrical from beginning to end, allows for an aircraft landing strip that will accommodate an aircraft to approach and land from either direction; single sided panels accommodates the aircraft unidirectionally.
