It's believed to date to 1951. The film uses animation and live action to explain how the radio compass, runway localizer, altimeter, directional gyro, artificial horizon, and marker beacons are utilized in the Air Force Landing System. Demonstrates instrument landing procedures on the Link Trainer. • 0:36: The film begins with shots of an air base in a fog. In conditions with low visibility, and no prospect of change for hours, pilots rely on radio and instruments for navigation and can even land safely in these conditions. • 0:41: Pilots can use radio and instruments to land safely. • 0:55: Air Force Instrument Landing System (ILS) helps pilots land. • 1:00: Pilots use radial compass, runway localizer, altimeter, directional gyro, and artificial horizon. • 1:18: Guiding stations are mobile and set up according to wind conditions. • 1:44: Runway localizer is a new component added to the compass locator system. • 2:02: Outer station located 3.2 miles from the inner station. • 2:20: Airplane approaches the field using radio range. • 2:33: Compass tuned to outer station for runway alignment. • 2:48: Altitude is adjusted for approach. • 3:00: Gyro checked for exact runway alignment. • 3:19: Steady glide maintained from inner station to landing. • 3:40: Pilots alternate tuning radio compass to two stations for alignment. • 4:11: Instrument landing procedure demonstrated on LINK instrument trainer. Here the hood is taken off so that the pilot's activities can be recorded by the camera. • 4:29: Pilot contacts tower for field and weather information. • 4:54: Pilot tunes to inner station and centers radio compass. • 5:34: Marker beacon indicates position over inner station. • 5:42: Pilot tunes to outer station and centers radio compass. • 6:07: Pilot continues for 30 seconds at 180° on the gyro. • 6:22: Offset turn executed. • 7:03: Turn stopped when radio compass is centered. • 7:17: Pilot in a LINK trainer tunes to inner station and centers radio compass. • 8:01: Altitude should be 200 ft at inner station. • 8:19: Descent maintained by runway localizer, directional gyro, and artificial horizon. • 8:42: Basic principles of instrument landing system apply to all landings. • 9:02: Review of approach and landing procedure. • 9:21: If altitude is 200 ft short of inner station, level off. • 9:40: If above altitude limit, go around and try again. • 9:50: Directional gyro and artificial horizon used for final approach. • 10:01: Artificial horizon helps smooth speed and vertical speed indications. • 10:45: Air Force ILS adaptable to different airplanes and conditions. The term Link Trainer, also known as the "Blue box" and "Pilot Trainer" is commonly used to refer to a series of flight simulators produced between the early 1930s and early 1950s by Link Aviation Devices, founded and headed by Ed Link, based on technology he pioneered in 1929 at his family's business in Binghamton, New York. During World War II, they were used as a key pilot training aid by almost every combatant nation. More than 500,000 US pilots were trained on Link simulators,. The Link Company, now the Link Simulation & Training division of CAE USA Defense & Security CAE Inc., continues to make aerospace simulators. Motion picture films don't last forever; many have already been lost or destroyed. For almost two decades, we've worked to collect, scan and preserve the world as it was captured on 35mm, 16mm and 8mm movies -- including home movies, industrial films, and other non-fiction. If you have endangered films you'd like to have scanned, or wish to donate celluloid to Periscope Film so that we can share them with the world, we'd love to hear from you.
