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.
A Fresnel lens (/ ˈ f r eɪ n ɛ l,-n əl / FRAY-nel, -nəl; / ˈ f r ɛ n ɛ l,-əl / FREN-el, -əl; or / f r eɪ ˈ n ɛ l / fray-NEL [1]) is a type of composite compact lens which reduces the amount of material required compared to a conventional lens by dividing the lens into a set of concentric annular sections.
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.
Adjacent to the runway is a standard aircraft carrier optical landing system Fresnel lens. Each landing is observed and graded by a Landing Signal Officer, a pilot who has been trained in the subspecialty of teaching aviators how to safely land on an aircraft carrier. [7] [8] [9]
It is equipped with a Fresnel lens optical landing system (FLOLS) at each approach end, as well as lit aircraft carrier flight deck landing areas at both ends, so pilots can simulate carrier landings. Apart from touch-and-go landings and take-offs, aircrews use the many ranges at NAF El Centro to develop their skills.
