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 affecting 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 Helmet Recommendation
The open cockpit of the Edge XT exposes the occupants to the elements during flight and exposes them
to objects outside of the aircraft in an emergency situation.
Helmets and eye protection are recommended for occupants for protection from precipitation, strike by
insects and birds. Helmets are also recommended for risk reduction during an emergency landing of the
aircraft. The helmets recommended for use in the aircraft are those certified to the EN 966 standard, that
is applicable to helmets for air sports. The standard prescribes tests for penetration resistance, shock
absorbing properties, field of vision and head mobility.
4.8 Normal Procedures Check List
The following checklists should be used as a reference. More detailed procedures are found in the
Amplified Procedures section, which follows.
Prior to flight a thorough pre-flight inspection of the aircraft should be carried out. Details of the pre-flight
inspection are shown earlier in this section.
WARNING
ENSURE THE AIRCRAFT IS EARTHED TO
AVOID STATIC DISCHARGE IGNITING FUEL
