진입등시스템/Approach Light System(ALS, ALSF-1/2, SSALF/R, MASLF/R, RAIL, ODALS)

1. U.S. FAA 근거 : FAA AIM 2-1-1p, PCG A-7p 2−1−1. Approach Light Systems (ALS) a. 목적 ALS provide the basic means to transition from instrument flight to visual flight for landing. Operational requirements dictate the sophistication and configuration of the approach light system for a particular runway. b. 설치 ALS are a configuration of signal lights starting at the landing threshold and extending into the approach area a distance of 2400−3000 feet for precision instrument runways and 1400−1500 feet for nonprecision instrument runways. Some systems include sequenced flashing lights whic..........
