REMOTE INDICATING MAGNETIC COMPASS

#1. A gyro-magnetic compass or magnetic heading reference unit is an assembly which always consists of : 1- a directional gyro 2- a vertical axis gyro 3- an earth's magnetic field detector 4- an azimuth control 5- a synchronising control The combination of correct statements is :

• A2 and 5
• B1, 3 and 5
• C2, 3 and 5
• D1 and 4

#2. A slaved directional gyro derives its directional signal from

• Aa direct reading magnetic compass
• Bthe flight director
• Cthe flux valve
• Dthe air data computer

#3. The gyro-magnetic compass torque motor:

• Acauses the directional gyro unit to precess
• Bcauses the heading indicator to precess
• Cfeeds the error detector system
• Dis fed by the flux valve
