English

Subject field(s)
  • Aircraft Piloting and Navigation
CONT

If an aircraft could hold an exact great circle heading and fly at a constant speed, its track would be slightly curved in space due to the rotation of the earth. In the northern hemisphere the aircraft curves to the right. This effect must be allowed for in aircraft instrumentation, liquid filled instruments, pendulums, accelerometers, etc.

English

Subject field(s)
  • Aeroindustry
CONT

The [FMS-90] equipment can also be used for great-circle navigation when operating in the VOR/DME mode : the computer draws a great circle track between the specified departure and destination points, and all the pilot has to do is to tune to selected VOR stations along this route; the FMS-90 can compute offsets from any one of the 5, 700 VOR/DME entries, of which the coordinates can be stored in its memory.

French

Domaine(s)
  • Constructions aéronautiques
CONT

Le FMS-90 peut également servir à la navigation orthodromique en mode VOR/DME: le calculateur établit la route orthodromique entre les points de départ et de destination indiqués et il suffit au pilote de s'accorder sur les stations VOR choisies le long de cette route; le FMS-90 peut calculer les décalages par rapport à n'importe lequel des 5700 points VOR/DME, dont les coordonnées peuvent être stockées dans sa mémoire.
