Les instruments gyroscopiques devraient toujours être bloqués avant d’effectuer des manœuvres acrobatiques et ce, pour éviter le culbutage qui risque d’endommager les coussinets.

Le gyroscope de l’horizon artificiel de la plupart des petits appareils se renverse si le tangage dépasse +/-70 degrés ou si l’angle d’inclinaison latérale dépasse 100 degrés. Si le gyroscope se renverse, les indications qu’il délivre ne sont pas fiables tant qu’il ne s’est pas réaligné, ce qui peut nécessiter plusieurs minutes de vol rectiligne à l’horizontale. Les avions de voltige ou les appareils plus importants sont souvent équipés de gyroscopes fiables jusqu’à 360 degrés de tangage et d’inclinaison latérale. 2, record 1, French, - culbutage

The heading indicator (HI) uses the principle of rigidity in space for it's operation. The gyro is mounted such that it registers changes around the vertical axis only; i.e. direction changes. The compass card attached to the gyro appears to the pilot as though it is turning. In reality, it and the attached gyro are remaining rigid in space, while the aircraft and case turn about the gyro. The HI is not automatically synchronized with the magnetic compass. It must be set to the compass heading while level on the airport surface prior to take-off. 13, record 3, English, - directional%20gyroscope

Le conservateur de cap, également appelé directionnel, est un gyroscope libre dont l'axe est orienté horizontalement selon la direction qui lui a été assignée lors de sa mise en rotation. Cette orientation sera prise pour référence horizontale. En choisissant le nord magnétique comme référence, cet appareil indiquera le cap magnétique de l'avion. Il faudra le «caler» avant chaque vol lorsque l'avion est aligné sur la piste(piste dont on connaît l'orientation). 10, record 3, French, - conservateur%20de%20cap

Le conservateur de cap, ou gyroscope directionnel, est l’un des trois instruments à gyroscope. Aligné avec le compas, il donne une indication précise et stable concernant le cap magnétique de l’appareil. Le conservateur de cap constitue une aide importante car le compas est sujet à des erreurs causées par l’accélération, la décélération et la courbure du champ magnétique terrestre, particulièrement sous les hautes latitudes. Il arrive fréquemment que le compas oscille; il est particulièrement difficile à lire dans les turbulences ou pendant les manœuvres. Fonctionnement. Le gyroscope du conservateur de cap pivote dans un plan vertical. Une carte comportant des caps maintient son orientation lorsque l’avion tourne. Le mouvement apparent de la carte donne au pilote une indication précise et instantanée du cap de l’avion et de la direction dans laquelle il tourne. La carte est marquée de 5 degrés en 5 degrés, avec une indication chiffrée tous les 30 degrés et les points cardinaux repérés par N, S, E, O. 11, record 3, French, - conservateur%20de%20cap

The first officer's duty during this manoeuvre was to monitor the alignment and advise the commander of the aircraft's ground speed displayed on the EFIS (Electronic Flight Instrument System).

Culminating a decade of pace-setting LITEF fiber optic gyro (FOG) research and development, the LCR-92 µ-AHRS strapdown Attitude and Heading Reference System ... offers near-inertial quality heading and attitude capability at a price and with the reliability that today's business aviation and regional airline operators demand. It is a cost-effective replacement for expensive-to-maintain gimballed attitude - directional - and rate - gyro-based systems, priced competitively with that 1960's technology but with up to five times the Mean Time Between Failure (MTBF). And it is smaller, lighter, and significantly less costly than other fiber optic gyro-based AHRS. 4, record 10, English, - strapdown%20attitude%20and%20heading%20reference%20system

DI - direction indicator. A gyro instrument which indicates the magnetic heading of an aircraft. The DI, also known as the directional gyro (DG), is free of the turning errors associated with magnetic compasses but is prone to precession (wander) and must be reset against the magnetic compass at intervals. 3, record 12, English, - reset

Aligning the Heading Indicator. On small aircraft like the Cessna 182RG, the pilot sets the heading indicator to coincide with the compass before takeoff and resets it periodically during flight to make sure that it remains in sync with the compass. The heading indicator drifts because it's based on a gyro, which precesses with time. 2, record 12, English, - reset

"Set" and "reset" express the same reality except for the time aspect and are not real synonyms. However, because of the necessity to periodically and continuously "reset" the gyros, one could say that the pilot "resets" the instruments in flight as well as he "sets" or "resets" them before take-off, referring to the last in-flight setting operation. "Reset" would be more appropriate for in-flight setting operation. 4, record 12, English, - reset

The basic attitude sensor was the three-gyro inertial reference package. It contained two air-tight integrating gyro units to sense pitch and yaw, and one miniature integrating gyro unit to sense roll. The pitch and roll gyros were torqued by signals obtained by two Barnes mod IIA infrared horizon sensors. Gyrocompassing oriented the vehicle to an orbit plane yaw reference by detecting a component of the programmed pitch rate through the roll horizon sensor. The geocentric pitch rate (typically 4 deg/min, for a low-altitude orbit) was programmed as a constant torque to the pitch gyro. This pitch component, if a yaw error was present, would be sensed differentially when compared with the roll components of the two horizon-sensor heads. The differential would be seen as a function of yaw error. 2, record 17, English, - roll%20component

The basic attitude sensor was the three-gyro inertial reference package. It contained two air-tight integrating gyro units to sense pitch and yaw, and one miniature integrating gyro unit to sense roll. The pitch and roll gyros were torqued by signals obtained by two Barnes mod IIA infrared horizon sensors. Gyrocompassing oriented the vehicle to an orbit plane yaw reference by detecting a component of the programmed pitch rate through the roll horizon sensor. The geocentric pitch rate (typically 4 deg/min, for a low-altitude orbit) was programmed as a constant torque to the pitch gyro. This pitch component, if a yaw error was present, would be sensed differentially when compared with the roll components of the two horizon-sensor heads. The differential would be seen as a function of yaw error. 2, record 18, English, - pitch%20component

During heading align, the rotor of the resolver is positioned so that it transforms the N-S and E-W liquid level signals into pitch and roll components which are referenced to heading. The pitch component is amplified, demodulated and summed with amplified and demodulated feedback signals from the VG [vertical gyro] roll and pitch pickoffs and the pitch synchro. The combined signal is then modulated, amplified and converted to DC [direct current] to drive the platform pitch gimbal torque motor until the input signals are nulled. 3, record 18, English, - pitch%20component

Durant l'alignement sur le cap, le rotor du résolver est mis en position de telle sorte qu'il transforme les signaux des niveaux à liquide N.-S. et E.-O. en composantes de tangage et de roulis en référence au cap. La composante de tangage est amplifiée, démodulée et composée avec des signaux de réaction amplifiés et démodulés venant des capteurs de roulis et de tangage du VG [gyroscope directionnel] et du synchro de tangage. Ce signal composé est alors modulé, amplifié et converti en courant continu pour entraîner le moteur couple du cardan de tangage de la plate-forme jusqu'à ce que les signaux d’entrée soient annulés. 2, record 18, French, - composante%20en%20tangage

Le conservateur de cap ou directionnel. Il présente l'avantage de conserver une référence de cap choisie par le pilote, quelle que soit la phase du vol de l'avion(montée, descente, variation de vitesse, etc..). Le directionnel est en effet un gyroscope dont le rotor tourne à vitesse élevée(de l'ordre de 10 000T/mn), or nous savons que la propriété fondamentale, d’un gyroscope est de garder une position fixe par rapport à l'espace. Si le pilote choisit de caler son conservateur de cap sur le nord magnétique, son directionnel lui fournira donc en permanence une indication stable de son cap magnétique. 2, record 19, French, - propri%C3%A9t%C3%A9%20garde%2Dcap
