Further Evaluation Of A Modified Controllable Beam Runway Light PDF Download

A study was made to determine the most effective, yet economical, system or combination of systems for use on other than precision approach runways. The following approach lighting aids were evaluated: (1) rotating incandescent runway end identifier lights, (2) condenser discharge runway end identifier lights, (3) rotating incandescent approach light beacons, (4) condenser discharge approach light beacons, Simpli fied approach lighting system, (6) shortened precision approach lighting system, and (7) wide beam circling guidance lights. The various systems were evaluated individually and in combination by flight testing under conditions of simulated and actual low visibilities. Pilot opinion and phototheodolite tracking data provided a basis for determing relative system effectiveness. Data obtained from an in-service evaluation of the rotating incandescent approach light beacons at New York International Airport were also considered in determing conclusions and recommendations. Recommendations were made for modification and adoption of the simplified approach lighting system as a standard for use on other than precision approach runways. (Author).
