What is used as the sensor in the fuel tank for an electronic-type fuel quantity indicating system?
Tubular capacitors that extend across the fuel tank from top to bottom
What is the principal upon which the electronic-type fuel indicating system operates?
Tubular capacitors extending across fuel tanks change their capacitance as the fuel level changes.
What is used as a sensor in the fuel tank for the oldest resistance-type fuel quantity indicating system?
A variable resistor with an arm that is moved by a float riding on top of the fuel in the tank
What are two types of fuel cells used in modern aircraft?
Integral fuel cells (cells that are a sealed-off portion of the structure), and bladder type cells
Why are fuel tanks divided into compartments or have baffles installed in them?
The compartments or baffles keep the fuel from surging back and forth as the aircraft changes its attitude in flight
What is the purpose of a drip gage in the fuel tank of a large aircraft?
The drip gage allows a mechanic to check the fuel level in a tank from the bottom of the tank
Where can you find the correct part number for the fuel quantity sensor to be installed in an aircraft fuel tank?
In the aircraft IPB
When must the fuel quantity indicating system indicate zero?
During level flight when the fuel in the tank is equal to the unusable fuel supply
