73. ENGINE FUEL SYSTEMS
73.00.00 General
The XT fuel system consists of one fuel tank centrally located underneath and to the rear of the
passenger seat of the aircraft. There is one fuel supply line that runs from the left rear of the fuel tank
and through to the mechanical fuel pump of the engine. All of the components for the engine are
standard as per the Rotax manuals, which should be consulted for maintenance information.
73.20.00 Controlling
The control of the throttle and choke systems for the engine are cable actuated by the pilot. The throttle
is situated on the right hand side of the aircraft, and has a double system that is actuated either by foot
or hand. The cables from each of the two are routed through a mixer device which allows each to be
depressed independently, even if the other is stuck for any reason. The mixer also has two cables from
it to the carburettors.
The throttle system has two cables that are both attached to a hand lever on the left hand side of the
seat frame.
73.30.00 Indicating
There is a supplementary fuel flow rate sensor that is in line with the fuel supply line. An electrical fuel
flow sensor supplies information to the SkyDAT data box mounted on the Tie Rod for the engine. The
digital display at the front of the aircraft displays the fuel consumption rate for the pilot. The total usage
information is also available if the counter is correctly reset after the fuel tank is filled. The remaining
fuel indication should be used in addition to the physical tank graduations that are visible on the pilots
right of the fuel tank.
