All fuel hoses are protected with certified glass-silicon rubber. ALPHA Trainer’s fuel system features
fuel return circuit into the fuel tank.
There is an electric - gauge style fuel quantity indication for the pilot.
NOTE The actual fuel consumption/flow and fuel quantity remaining are calculations based on en-
gine rpm and manifold pressure. These settings are to be used as a guide only and are NOT to be relied
upon for the safe operation of the aircraft. If in doubt confirm the fuel quantity remaining before flight.
Draining of water and/or particles is carried out by draining the contents of the gascolator, installed
below the bottom engine cowl and reachable through a dedicated placarded opening. Unscrew the
discharge valve and drain at least 1 cup of fuel in a transparent canister, verify for water/particle con-
tamination. Always fasten the drain valve before flight!
When using the single point fuel valve, found below the draining opening (placarded), make sure you
have closed it before flight. The single point fuel valve can either be used for fuelling the aircraft by us-
ing a pump and container, or for discharging all of the fuel on board before disassembling the aircraft.
