ABSTRACT:
Airport twenty-four hour pilot information markers are provided to tell the pilot: upon takeoff or landing how many feet of runway remain; before takeoff or after landing what taxiway he or she is to follow; what is the direction, inboard, outboard, north, south, east, or west, etc.; what is the intersection; what is the holding position; and/or what is the destination; etc. In respect to a runway distance remaining embodiment, the construction and installation is as follows: a four feet square aluminum sheet, at least one hundred thousandths of an inch thick has high intensity reflective Scotchlite reflective material, applied to each side, with white denoting the numeral and green the background, to reflect the light of airplane landing lights; each Scotchlite covered sheet is then pivotally supported one foot down from the top along each side to a 11/2 fiberglass pipe; in turn below telescopically received in a 2" fiberglass pipe; in turn cemented in place in the ground, often utilizing a transverse holding pin; and transverse adjustment and holding pins are directed through the 2" and 11/2" fiberglass pipes just about ground level, when the top edge of this pilot information marker is level, thereby fully retaining the information marker. Near ground level the 11/2 foot fiberglass pipes preferably have a frangible portion which breaks, if an airplane in making a deviated landing, strikes the information marker. Another embodiment utilizes two four feet square aluminum sheets, having only one side of each sheet covered with green and white Scotchlite reflective material, removably placed in a frame supporting them. The frame is in turn supported in like manner. Another embodiment includes the select placement of radio isotopes in tubes, such as tritium in tubes, to create illuminated information markers, where they are not positioned to reflect the light from landing lights of airplanes, or where such tritium energy lighting is used in conjunction with reflective informational markers.
