Ols Military - Collectively, the apparatus on which the lights are mounted is called "the lens". It is turned on/off and brightness is adjusted on the lens itself for ground based units, and remotely for shipboard units. In both cases, the lens is connected to a hand-controller (called a "pickle") used by the LSOs. The pickle has buttons that control the wave-off and cut lights. There are three shipboard installation modes: STATION 1 is immediately forward of the FLOLS and uses the FLOLS waveoff, datum, and cut light displays. STATION 2 and 3 are independent of FLOLS and are located on the flight deck port and starboard side respectively. MOVLAS is nothing more than a vertical series of orange lamps that the LSO controls manually with a hand controller to simulate a ball. The mirror landing aid is a gyroscopically-controlled concave mirror on the port side of the flight deck. On both sides of the mirror there is a line of green colored "datum lights". A bright orange "source" light shone through the mirror creating a "ball" (or "meatball" in later USN parlance) that the aviator could see approaching. The position of the ball relative to the datum lights indicated the position of the aircraft relative to the desired glidepath: if the ball was above the datum, the aircraft was high; below the datum, the plane is low; between the datum, the airplane is on the glidepath. Gyro stabilization compensates for most of the movement of the flight deck due to the sea, providing a constant glidepath.

MOVLAS is a backup visual landing aid system used when the primary optical system (FLOLS) is inoperable, stabilization limits are exceeded or unreliable (mainly due to heavy seas causing the pitching deck), and for pilot/LSO training. The system is designed to display glideslope information in the same visual form that FLOLS displays. The rear of HMAS Melbourne's mirror landing aid. The datum lamps and the two large "wave off" lamps are clearly visible as are, on the left of the photo, four of the orange lamps projected onto the mirror to provide the "ball". For shore-based Optical Landing Systems, the lights are typically mounted on a mobile unit plugged into a power source. Once set up and calibrated, there are no moving parts in the unit. Shipboard units are more complex because they must be gyroscopically stabilized to compensate for ship motion. Additionally, the shipboard units are mechanically moved (the "roll angle") to adjust the touchdown point of each aircraft. With this configuration, the tailhook touchdown point can be precisely targeted based on the tailhook-to-pilot eye distance for each type of aircraft.

Later systems retain the same basic mirror landing aid function, but have upgraded components and functionality. The concave mirror, light source combination is replaced by a series of fresnel lenses. The Mk 6 Mod 3 FLOLS was tested in 1970 and has not changed much, except when the lift of the ship is taken into account in an Inertial Stabilization system. These systems are still widely used on runways at US Naval Air Stations.[4] What's going on with your task force? We want to hear your stories about training, MWR events, and more!

IFLOLS, designed by engineers at NAEC Lakehurst, NJ, retains the same basic design but improves on FLOLS, providing a more accurate indication of the aircraft's position on the glideslope. A prototype IFLOLS was tested on the USS George Washington (CVN-73) in 1997 and every deploying aircraft carrier since 2004 has the system. The Improved Fresnel Lens Optical Landing System, IFLOLS, uses fiber optic "source" light, which is emitted through lenses to reflect a sharper, crisper light. This allowed pilots to start flying the "ball" further away from the ship making the transition from instrument flight to visual flight more seamless. Additional improvements include better deck motion compensation due to internalization of the mechanism. The LSO, who is a specially qualified and experienced Navy pilot, provides additional input to the pilot via radios, advising on power requirements, position relative to the glide path and centerline. The LSO can also use a combination of lights attached to the OLS to indicate "around" with bright red, flashing wave off lights. Additional signals, such as "cleared to land," "add power," or "divert" may be signaled with a row of green "cut" lights or a combination thereof.

Others are the steam catapult and the angled flight deck. The Mirror Landing Aid was invented by Nicholas Goodhart.[2] It was tested on the carriers HMS Illustrious and HMS Indomitable before being introduced on British carriers in 1954 and on US carriers in 1955. An optical landing system (OLS) (nicknamed "meatball" or simply, "Ball") is used to provide glidepath information to pilots in the terminal phase of landing on an aircraft carrier.[1] From the beginning of aircraft landing on ships in the 1920s until the introduction of OLSs, pilots relied solely on their visual perception of the landing area and the assistance of the Landing Signal Officer (LSO in the US Navy, or "batsman " in the Commonwealth navy). The LSOs used colored flags, cloth paddles and lighted wands. We may request that cookies be set on your device.

Initially, the device was thought to allow the pilot to land without direction from the LSO. However, accident rates actually increased when the system was first introduced, so the current LSO integration system was developed. This development, along with others noted, contributed to an increase in the US carrier landing accident rate from 35 per 10,000 landings in 1954 to 7 per 10,000 landings in 1957.[3] We also use various external services such as Google Webfonts, Google Maps, and external Video providers.

With point stabilization, the glide slope is fixed around a point 2500 feet behind the lens. In Line, the glide path stabilizes to infinity. As the deck lifts and rolls, the light sources are locked to maintain a continuous glideslope fixed in space. Inertial stabilization works like Line, but also compensates for flight deck heave (the straight up and down part of the deck's motion). If the IFLOLS cannot keep up with the deck movement, the LSO can switch to MOVLAS or simply conduct "LSO talk downs." Only the most experienced LSOs will conduct a talk down or control aircraft with MOVLAS during heavy seas.[6] As these cookies are strictly necessary to deliver the website, rejecting them will have an impact on how our site works.
