Aircraft fuel systems Flashcards
(13 cards)
what is the purpose of a fuel jettisoning(dump) system
to reduce the weight of the aircraft to a specified landing weight
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 that the cell fits into
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 indicators
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
single point fueling system
what method may be used to check a fuel tank for leaks after a weld has been performed
the tanked 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
