The IR [infrared] searchlight is most effective below 200 feet above highest obstacle(AHO). However, in clear dark conditions it may be used to assist in terrain and obstacle illumination for low level navigation to altitudes in excess of 250 feet.

CONT

Le projecteur infrarouge est vraiment efficace à moins de 200 pieds de l'obstacle le plus élevé. Toutefois, au cours des nuits sans nuages, on peut s'en servir pour éclairer le terrain et les obstacles pour la navigation à basse altitude au-dessus de 250 pieds.

Record 4 2019-01-14

English

Subject field(s)
  • Weapon Systems
  • Control Systems (Electronic Instrumentation)
CONT

It was not possible to store data for an entire flight, so smaller segments were stored and used to periodically update a conventional navigation system in what was called a TERCOM-Aided Inertial Navigation System(TAINS). In TAINS, the inertial guidance system navigated the missile from one [terrain contour matching(TERCOM) ] checkpoint to the next, with the computer updating the inertial guidance system and correcting the missile's course.

  • Air Safety
CONT

The Federal Aviation Administration(FAA) has approved the use of Allied Signal' s enhanced ground proximity warning system(EGPWS) on all American Airlines Boeing 757 aircraft.... The new EGPWS provides a detailed map of the terrain in the vicinity of the aircraft. Using an existing navigation system, such as the Global Positioning System(GPS), the aircraft's position is correlated with a database-driven terrain map which provides the pilot with real time awareness of the aircraft's position. The moving map, which is displayed on a cockpit screen, will aid the pilot in maintaining proper altitude and terrain clearance.

DFAD is a standard NIMA [National Imagery and Mapping Agency] product that supports radar return simulation, navigation and terrain obstruction studies. When combined with DTED [Digital Terrain Elevation Data], DFAD provides an off-line data base for use by weapon system flight simulators and other types of simulation, such as line of sight, obstruction and perspective view development. It portrays major natural and man-made features on the Earth's surface; the features and associated attributes of which are generally of radar reflectance significance. Content is derived from both cartographic and photo-grammetric source material.

LANTIRN consists of a navigation pod and a targeting pod integrated and mounted externally beneath the aircraft. The AN/AAQ-13 navigation pod provides high-speed penetration and precision attack on tactical targets at night and in adverse weather. The naviation pod also contains a terrain-following radar and a fixed infrared sensor, which provides a visual cue and input to the aircraft's flight control system, enabling it to maintain a preselected altitude above the terrain and avoid obstacles. This sensor displays an infrared image of the terrain in front of the aircraft, to the pilot, on a head-up display. The navigation pod enables the pilot to fly along the general contour of the terrain at high speed, using mountains, valleys and the cover of darkness to avoid detection.

The Goodyear Aircraft Corporation developed ATRAN(Automatic Terrain Recognition And Navigation), a radar map-matching system) in which the return from a radar scanning antenna was matched with a series of "maps" carried on board the missile which corrected the flight path if it deviated from the film map. The company began lab tests in March 1948, flight tests in October of that year.
