RUNWAY END IDENTIFIER LIGHTSWhen separate on−off controls are provided, operaterunway end identifier lights:a. When the associated runway lights are lighted.Turn the REIL off after:1. An arriving aircraft has landed.2. A departing aircraft has left the trafficpattern area.3. It is determined that the lights are of nofurther use to the pilot.b. As required by facility directives to meet localconditions.c. As requested by the pilot.d. Operate intensity setting in accordance with thevalues in TBL 3−4−1 except as prescribed insubparas b and c above.TBL 3−4−1REIL Intensity Setting−Three Step SystemSettingsVisibilityDayNight3 Less than 2 miles Less than 1 mile2 2 to 5 miles inclusive 1 to but not including 3miles1 When requested 3 miles or more3−4−3.

Other VASI systems in useinclude those that are operated remotely from the controltower. These systems may consist of either a photoelectricintensity control with only an on−off switch, a two stepintensity system, or a three step intensity system.REFERENCE−FAAO 7210.3, Visual Approach Slope Indicator (VASI) Systems,Para 10−6−5.FAAO 6850.2, Visual Guidance Lighting Systems.3−4−4.
