Q4. The principle of capacity gauges is based on the:
capacitance variation of a given capacitor with the type of dielectric.
Q5. 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:
twice that of air and varies directly with density.
Q6. The capacity fuel gauges provide information:
on mass whose indication is independent of the temperature of the fuel.
Q7. The float type fuel gauges provide information on:
volume whose indication varies with the temperature of the fuel.
Q8. The basic principle used for measuring a quantity of fuel in a transport airplane equipped with “capacitor” gauges is that the:
capacity of a capacitor depends on the nature of the dielectric in which it is immersed.
Q9. The advantages of an electric float gauge are: 1- ease of manufacture 2- independence of the indication relative to the variations of the aircraft power system if the measurement is made by a ratiometer 3- independence of the indication relative to the variations of the aircraft power system if the measurement is made by a galvanometer 4- independence of the indication re

Q10. If the tanks of your airplane only contain water, the capacitor gauges indicate:
a mass of water different from zero, but inaccurate.
Q11. The indication of a fuel float gauge varies with : 1- aircraft attitude 2- accelerations 3- atmospheric pressure 4- temperature The combination of correct statements is :
1,2,4
Q12. In an average or heavy weight transport airplane, generally, the fuel quantity is measured by “capacitor” gauges because these give : 1- indications partly independent of fuel temperature variations 2- indications almost independent of the airplane’s attitude and accelerations 3- indications expressed in density The combination regrouping all the correct statements i
