- Chapter 17: Aeromedical Factors › Ground Lighting Illusions › How To Prevent Landing Errors Due to Optical Illusions
Ground Lighting Illusions Lights along a straight path, such as a road or lights on moving trains, can be mistaken for runway and approach lights. Bright runway and approach lighting systems, especially where few lights illuminate the surrounding terrain ... Optical Illusions To prevent these illusions and their potentially hazardous consequences, pilots can: 1. Anticipate the possibility of visual illusions during approaches to unfamiliar airports, particularly at night or in adverse weather conditions. Consult airport diagrams and the Chart Supplement…

Runway Lighting Runway centerline lighting system (RCLS)—installed on some precision approach runways to facilitate landing under adverse visibility conditions. They are located along the runway centerline and are spaced at 50-foot intervals. When viewed from the landing threshold ... runway centerline lights are white until the last 3,000 feet of the runway. The white lights begin to alternate with red for the next 2,000 feet. For the remaining 1,000 feet of the runway, all centerline lights…

Runway Lighting There are various lights that identify parts of the runway complex. These assist a pilot in safely making a takeoff or landing during night operations. Runway End Identifier Lights (REIL) Runway end identifier lights (REIL) are installed ... positive identification of the approach end of a particular runway. The system consists of a pair of synchronized flashing lights located laterally on each side of the runway threshold. REILs may be either omnidirectional or unidirectional facing the approach area…

green for a heliport • Two quick white flashes alternating with a green flash identifying a military airport Approach Light Systems Approach light systems are primarily intended to provide a means to transition from instrument flight to visual flight for landing ... system configuration depends on whether the runway is a precision or nonprecision instrument runway. Some systems include sequenced flashing lights that appear to the pilot as a ball of light traveling toward the runway at high speed. Approach lights…

night, there is a natural tendency to fly a lowerthan-normal approach. Elements that cause any type of visual obscurities, such as rain, haze, or a dark runway environment, can also cause low approaches. Bright lights, steep surrounding terrain ... being too low with a tendency to fly a higher-than-normal approach. A set of regularly spaced lights along a road or highway can appear to be runway lights. Pilots have even mistaken the lights on moving trains…
