Questions for REMOTE INDICATING MAGNETIC COMPASS
Answer the following questions
Test Mode
Training Mode
1. A slaved directional gyro derives its directional signal from
the air data computer
the flux valve
a direct reading magnetic compass
the flight director
2. The heading information originating from the gyro-magnetic compass flux valve is sent to
heading indicator
amplifier
error detector
erector system
3. 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
1 and 4
2, 3 and 5
1, 3 and 5
2 and 5
4. The gyro-magnetic compass torque motor
causes the directional gyro unit to precess
feeds the error detector system
is fed by the flux valve
causes the heading indicator to precess
5. The input signal of the amplifier of the gyro-magnetic compass resetting device originates from the
directional gyro unit
directional gyro erection device
flux valve
error detector
6. Heading information from the gyro-magnetic compass flux gate is transmitted to the
erecting system
amplifier
error detector
heading indicator
7. A flux valve senses the changes in orientation of the horizontal component of the earth's magnetic field : 1- the flux valve is made of a pair of soft iron bars 2- the primary coils are fed AC voltage 3- the information can be used by a “flux gate” compass or a directional gyro 4- the flux gate valve casing is dependent on the aircraft three inertial axis 5- the accuracy of the value of the magnetic field indication is less than 0.5% The combination of correct statements is
1, 3, 4 and 5
1, 4 and 5
3 and 5
2, 3 and 5
