Landing lights are usually extinguished in cruise flight, especially if atmospheric conditions are likely to make the lights reflect or glare back into the eyes of the pilots. However, the brightness of landing lights makes them useful for increasing the visibility of an aircraft to other pilots, and so pilots are often encouraged to keep their ...
[5] [2] [7] Planes can acknowledge the instruction by rocking their wings, moving the ailerons if on the ground, or by flashing their landing or navigation lights during hours of darkness. [ 6 ] [ 7 ] Air traffic control signal light guns are typically specified with a (white) center beam brightness of > 180,000 - 200,000 candela, [ 1 ] [ 8 ...
The improved fresnel lens optical landing system, IFLOLS, uses a fiber optic "source" light, projected through lenses to present a sharper, crisper light. This has enabled pilots to begin to fly "the ball" further away from the ship making the transition from instrument flight to visual flight smoother.
The PAPI can be seen to the right (non-standard) side of the runway. The aircraft is slightly below the glideslope. A precision approach path indicator (PAPI) is a system of lights on the side of an airport runway threshold that provides visual descent guidance information during final approach.
Each light is designed so that it appears as either white or red, depending on the angle at which it is viewed. When the pilot is approaching the lights at the proper angle, meaning the pilot is on the glide slope, the first set of lights appears white and the second set appears red. When both sets appear white, the aircraft is too high, and ...
Line-up with the landing area is achieved by lining up painted lines on the landing area centerline with a set of lights that drops from the back of the flight deck. Proper glideslope is maintained using an optical landing system ("meatball"), either the Fresnel lens optical landing system (FLOLS), improved FLOLS, [19] or a manually operated OLS.
Approach lights at Jyväskylä Airport, Finland The approach lighting system of Bremen Airport Approach lighting at Love Field, Dallas. An approach lighting system (ALS) is a lighting system installed on the approach end of an airport runway and consisting of a series of lightbars, strobe lights, or a combination of the two that extends outward from the runway end.

The microwave landing system (MLS) is an all-weather, precision radio guidance system intended to be installed at large airports to assist aircraft in landing, including 'blind landings'. [1] MLS enables an approaching aircraft to determine when it is aligned with the destination runway and on the correct glidepath for a safe landing.
