Fuel Systems Flashcards
The capacitance type fuel gauging system indicates the fuel quantity by measuring?
The dielectric change between fuel and air.
Failure of a capacitive fuel indication system will be indicated by?
A full deflection of the gauge to empty.
The use of MOGAS, compared to AVGAS, would lead to a higher risk of?
Ice forming in the carburettor.
