A gyroscope instrument for indicating direction, containing a free gyroscope which holds its position in azimuth and thus indicates angular deviation from a pre-set heading. 12, record 1, English, - directional%20gyroscope

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 1, 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 1, French, - conservateur%20de%20cap
Record number: 1, Textual support number: 2 CONT
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 1, French, - conservateur%20de%20cap

As a CME [Coronal Mass Ejection] hits the magnetosphere, the compression of the magnetic field produces an increase in the field measured at ground level. This gives a characteristic rise in the field and is known as a Sudden Storm Commencement(SSC). Not all SSCs are followed by auroral activity, but it is a good early indicator. If the solar wind speed and IMF [Interplanetary Magnetic Field] direction are favourable, the energy in the magnetosphere will gradually build up into a large storm, with the magnetic field decreasing and changing rapidly. 2, record 2, English, - sudden%20storm%20commencement
