The HSI, or Horizontal Navigation Indicator or Pictorial Navigation Indicator, is perhaps one of the most useful although misunderstood instruments around... it combines your directional gyro and Nav indicator into one instrument that reduces pilot workload by providing heading, course reference, course deviation and glide slope information all in one visual aid... You may also consider a slaved HSI. Slaving automatically compensates for gyro heading errors and keeps your HSI in agreement with your compass. It uses a magnetic flux sensor mounted in the wing or tail of your aircraft to sense changes in magnetic heading and sends corrective signals to your HSI. 2, record 4, English, - directional%20heading

Heading Hold (HH) or Heading Lock. A feature mode of some gyros that stands out by its property to hold the heading of a helicopter and resist the tendency to weathervane.

L'alignement rapide de cap implique le fonctionnement de trois boucles d'asservissement distinctes : la boucle d'asservissement variation/grivation, la boucle d'asservissement du cardan azimutal et la boucle d'asservissement de mise en position résultante. La boucle d'asservissement de variation/grivation répond aux informations sur le cap magnétique données par le détecteur de magnétisme. La boucle d'asservissement du cardan azimutal répond au signal d'erreur venant du synchro azimutal TX. Dans la boucle d'asservissement de mise en position résultante, les deux autres boucles sont comparées et le signal d'erreur qui en résulte, si tel est le cas, est utilisé pour mettre en position le cardan azimutal. 1, record 12, French, - boucle%20d%27asservissement%20de%20variation%2Fgrivation

Dead reckoning is a technique of computing the position of a vehicle from its distance and heading measurements. It is an inertial system which uses two independent sensors from which distance and heading information can be extracted. Because each position is relative, cumulative drift errors occur on an average of 2% of the distance traveled. The system consists of a magnetic compass or gyroscope for heading and odometer for distance. Dead reckoning is often combined with map matching to correct for drift errors. It performs well when combined with highly accurate digital maps. It can also be used to back up GPS during satellite visibility outages. 3, record 13, English, - cumulative%20drift

To minimize cumulative drift, verticial gyros may be slaved, or caged, to the gravity vertical. Caging is automatically discontinued whenever the airplane is in a steady turn. 4, record 13, English, - cumulative%20drift

A large variety of inertial navigation system configurations have been developed recently. Analysis of these systems indicates that they all have the same basic error characteristics, that is, random gyro drift, accelerometer bias and scale factor errors, alignment error, etc., and they affect all systems in a similar manner. 2, record 14, English, - alignment%20error

The alignment error signal whether it be manually inserted, stored information or magnetic information, is fed from the MAN/STORE/MAG switch, on the controller to the heading card in the EU [electronic unit]. During both rapid alignment and main alignment, an amber warning light, part of the auto align pushbutton, lights to warn the operator that either rapid or main align is in progress. 3, record 14, English, - alignment%20error

Le signal d'erreur d'alignement, qu'il soit introduit manuellement, mis en mémoire ou de nature magnétique, est envoyé hors du contrôleur, à partir du sélecteur MAN/STORE/MAG jusqu'à la carte de cap. Durant l'alignement rapide et l'alignement principal, une lampe d'avertissement de couleur jaune, qui fait partie [intégrante] du bouton-poussoir AUTO ALIGN, s'allume pour avertir le pilote ou le technicien que soit l'alignement rapide soit l'alignement principal est en cours. 1, record 14, French, - erreur%20d%27alignement
