4.6 Fuelling
Fuel flow is from a single fuel tank fitted with a self-venting tube. The fuel system is fitted with a shut off
valve located on the rear left hand side of the seat frame. Be sure this valve is in the
ON
position before
starting engine.
Never refuel if fuel could be spilled on hot engine components. Use only safety approved fuel containers
and never transport fuel in an unsafe manner.
The fuel tank has a water drain mounted at the
base and to the rear of the tank. The fuel system
has an in-line fuel filter, which is mounted at the
front of the tank. This filter can be easily
disassembled for cleaning and inspection (see
base maintenance manual).
The Edge XT series fuel levels are marked on the right side of the fuel tank. The fuel levels are marked
at 10 litres, 20 litres, 30 litres, 40 litres, 50 litres and 60 litres.
4.6.1
Fuel Tank Capacity
The properties of the fuel tank material cause an increase in capacity after the first 2 to 3 tanks of fuel.
Initial capacity is 64 litres with the "aged" capacity 70 litres. The fuel level markings have been
positioned for the fuel tank capacity at 70 litres.
4.6.2
Fuel Quantity
A sight gauge is provided on the starboard side of the aircraft, visible through the soft side. Its purpose
is to provide fuel volume measurement for calculation of aircraft weight during fuelling of the aircraft and
to provide the pilot with a visual indication of the quantity of the remaining fuel. The calibration is valid
for the aircraft sitting on level ground and indicates total fuel, not usable fuel.
The trike base assumes various flight attitudes according to weight, flight, speed and power effecting the
indicated value of fuel quantity in flight. The useable fuel quantity is selected for the worst case
condition of aircraft attitude.
Zero useable fuel is indicated by the fuel level reaching the bottom of the sight gauge during level flight.
When the level indicates zero useable fuel, the tank contains 3 litres of unusable fuel.
4.7 Engine Lubricating Oil
Engine lubrication is supplied via the oil injection
system which is gravity fed. The oil consumption is
defined by engine rpm and the lever position. The
lever is actuated via a Bowden cable connected to
the throttle cable. The oil injection system has a
capacity of 2 litres.
The nominal oil usage is 50:1 (2%) which would
require 1.4 litres for a full tank of fuel.
The photo opposite gives an indication of oil levels
required for the nominated fuel level. The oil tank
has a low oil level switch (Alarm Level), which
actuates the alarm on the Skydat instrument.
However if the oil tank is filled when the fuel tank is
filled the low level alarm should never come on.
The remaining quantity of oil at ”Alarm Level” is
500mL when the alarm is actuated which leaves
enough oil to find a suitable landing area.
