FUEL SYSTEM
8.1. GENERAL PROVISIONS
The fuel system (Fig. 8.1) is designed for storing fuel in the helicopter and supplying the engine with it. The fuel used is high-octane petroleum of no less than 95 quality. Fuel tank capacity is 80 liters. The fuel is supplied from the tank to the engine through two fuel pumps. The fuel quantity in the tank is monitored by a fuel gauge, which has an indicator in the middle of the control panel. Monitoring of the pumps is done through annunciation panels.
Monitoring the engine fuel supply is done with the help of pressure indicator, which is situated on the control panel.
