When would a fuel jettison system be required for small aircraft? | It is required when the maximum takeoff weight exceeds the maximum landing weight |
What are two types of fuel tanks (cells)? | A bladder-type fuel tank and an integral fuel tank |
What supports the weight of fuel in a bladder-type fuel cell? | The structure of the cavity |
What is wet wing-type construction? | Integral fuel tanks |
What indicators could be used to determine when there may be danger of ice crystals forming in the fuel of a turbine-powered aircraft? | Fuel temperature or a differential pressure type indicator |
What is an electrical operated fuel tank shutoff valve in transit light? | A light that indicates when the valve is in motion |
What is the pressure fueling system sometimes referred to as? | Single-point fueling system |
What method may be used to check a fuel tank for leaks after a weld has been performed? | The tank is pressurized with 1/2 to 3 psi air pressure and a soapy solution is added to detect any leaks |
What should be done with old gaskets and seals when replacing fuel system components? | They should be removed and replaced with new ones |
What are four types of fuel quantity gauges in use today? | Sight glass, mechanical, electrical, and electronic |
What is the purpose of fuel tank internal baffles? | To resist fuel surging caused by changes in the attitude of the aircraft |
Why should you wait a period of time after fueling before checking fuel sumps? | To allow time for water and sediment to settle to the drain point |
