MAIN MECHANICAL BOOST PUMP
The mechanical boost pump is attached to accessory gearbox and supplies
fuel necessary for engine operation.
ENGINE FUEL SYSTEM
The engine fuel system consists of a fuel regulator, pumps, filters, a fuel
divider and fuel nozzles. The system provides the fuel flow necessary to
satisfy the engine power and rating needs.
The fuel coming from airplane system goes through a heater which is
automatically controlled by a thermostatic valve.
FUEL GAGING INSTALLATION
Fuel gaging installation is a capacitive type. Fuel data are displayed in us
gallons. Three fuel level gages are installed in each tank. The wing root side
fuel level gage is equipped with a low level detector which leads to fuel low
level CAS messages appearance, when usable fuel quantity remaining in the
concerned fuel tank is under about 9 us gal (34 Litres).
