Airport runway guard light

An improved runway lighting system comprises a first set of runway lights providing illumination in one direction along the runway, a second set of runway lights providing illumination in the opposite direction along the runway and a switching unit for switching on either the first set of lights or the second set of lights, depending on the direction of approach of incoming aircraft. A control unit provides current pulses along existing runway circuitry to operate the switching unit. Circuitry in the switching unit determines which set of lights to illuminate based upon the amplitude and duration of the current pulse. A selector switch may also be provided in the control tower to remotely operate the control unit.

Runway lighting system

An aircraft guidance light fixture housing for aircraft runways and taxiways includes a generally cylindrical rotationally molded plastic canister or housing member having an intermediate cylindrical wall section which is of an outer diameter slightly less than the inner diameter of the remaining wall sections of said housing member whereby the housing member may be cut in predetermined spaced apart positions to remove a portion of the housing member and permit telescoping one of the remaining sections into the other remaining section. The overall height of the housing member and the rotational position of one housing section relative to the other may be determined by the cutting and reassembly process. A support ring is mounted on the housing member and includes a peripheral flange of a diameter greater than the housing member so that aircraft loads on the light fixture may be transmitted directly to the runway structure and not through the housing. The housing assembly is installed in a runway structure by predetermining the overall height of the housing, cutting the housing member to provide the predetermined height of the housing assembly, installing the housing with one section rotationally positioned relative to the other in a predetermined position and encapsulating the housing and the support ring by adding runway structure material to secure the housing in a predetermined position.
