A flux valve detects the horizontal component of the earths magnetic field

1- the flux valve is made of a pair of soft iron bars
2- the information can be used by a “flux gate” compass or a directional gyro
3- the flux gate valve casing is dependent on the aircraft three inertial axis
4- the accuracy on the value of the magnetic field indication is less than 0,5(degrees).
The combination regrouping all the correct statements is :
A: 1-2-4
B: 1-2-3-4
C: 2-4
D: 1-3-4

 

 

 

 

 

 

 

 

Answer: C

The gauge indicating the quantity of fuel measured by a capacity gauging system can be graduated directly in weight units because the dielectric constant of fuel is:

A: twice that of air and varies inversely with density.
B: the same as that of air and varies directly with density.
C: twice that of air and varies directly with density.
D: the same as that of air and varies inversely with density.
