10.4. FUEL LOADS
FUEL LOADS - QUIK
The fuel tank is 65 litres capacity, including 1.6 litres unusable, giving 63.4 litres useable. The weight of the
fuel is 0.718 x 65 = 46.7 kg (102lb). The larger tank is 0.5kg heavier than the 47 litre tank. The fuel load
limitations for the range of allowable cockpit loads and aircraft empty weights are placarded in the cockpit as
follows:
EMPTY WEIGHT
COCKPIT LOAD
MAX FUEL LEVEL
205kg (451lbs)
Up to 157kg (345lbs)
65 litres (full)
205kg (451lbs)
200kg (440lbs) - max. load
5 litres
220kg (484lbs) - max. empty weight
172kg (379lbs)
23 litres (1/3 full)
220kg (484lbs) - max. empty weight
Up to 142kg (312lbs)
65 litres (full)
Example loading problem:
Aircraft empty weight:
202kg (445lbs)
Pilot 1:
90kg (198lbs)
Pilot 2:
90kg (198lbs)
Total:
382kg (841lbs)
Max AUW = 409kg, therefore (409 - 382)kg = 27kg or (900 - 841)lbs = 59lbs
The specific gravity of fuel is taken to be 0.718 g/cc (1.58lbs/cc)
Therefore maximum fuel = 27/0.718 = 37 litres or 59/1.58 = 37 litres.

The fuel tank is 65 litres capacity, including 1.6 litres unusable, giving 63.4 litres useable. The weight of the
fuel is 0.718 x 65 = 46.7 kg (102lb). The fuel load limitations for the range of allowable cockpit loads and
aircraft empty weights are placarded in the cockpit as follows:
EMPTY WEIGHT
COCKPIT LOAD
MAX FUEL LEVEL
217kg (477lbs)
Up to 186kg (409lbs)
65 litres (full)
226kg (497lbs)
220kg (484lbs) - max. load
5 litres
265kg (583lbs) - max. empty weight
168kg (370lbs)
23 litres (1/3 full)
265kg (583lbs) - max. empty weight
Up to 138kg (304lbs)
65 litres (full)
Example loading problem:
Aircraft empty weight:
217kg (477lbs)
Pilot 1:
90kg (198lbs)
Pilot 2:
110kg (242lbs)
Total:
417kg (917lbs)
Max AUW = 450kg, therefore (450 - 417)kg = 33kg or (990 - 917)lbs = 73lbs
The specific gravity of fuel is taken to be 0.718 g/cc (1.58lbs/cc)
Therefore maximum fuel = 33/0.718 = 46 litres.
10.5. CENTRE OF GRAVITY
Trike
The centre of gravity (CG) of the trike is not very critical - it only affects the range of pitch control movement,
not the trim speed. The CG of both the rear seat occupant and the fuel are as close as possible to the hang
