Q9. What does RIC/GMC mean?
Remote Indicating Compass / Gyro Magnetic Compass
Remote Indicating Compass / Gravity Measurements Compass
Range of Internal Calibration / Gyro Magnetic Calibration
Remote Internal Calibration / Gyro Magnetic Calibration
Q10. RIC/GMC is usually placed...
Where aircraft magnetic perturbations are greater
Where the instruments have more air cooler flow
Where aircraft magnetic perturbations are not important
All of the above are correct
Q11. About Turn and balance indicator, what sentence is wrong?
Turn indicator displays the rate of, and direction of turn, using gyroscopic principles.
Balance indicator shows if the plane performs balanced or unbalanced turn (skidding or sideslipping)
In general, the instrument show how the aircraft change the pitch.
Balance indicator has a black ball in a liquid filled glass tube.
Q12. Related with Inertial Navigations Systems, what sentence is wrong?
The velocity and position of the aircraft is obtained by measuring its acceleration and integrating it twice.
A disadvantage is that we have to measure the acceleration vector, in module and direction, and perform integrals
An advantage is that it is not necessary a good precision of the system alignment with True North, because the quality information not depends on that.
Classification: Gimballed INS and Strapdown INS.
Q13. What of the following are Components of the Gimballed INS?
Inertial Navigation Unit
Mode Selector Unit
Control Display Unit

Q3. Which is the function of the AAS (ALTITUDES ALERTING SYSTEM)
Set QNE (1013 mb) to the QNH of the aerodrome
