페이지 인쇄f) Empty weight
The standard empty weight which is used to calculate the reference empty weight of the whole
aircraft does not include the options stated hereafter. So, think of taking from the useful weight
indicated on the third page of the user's manual of the wing, the weight of each option.
g) Options
1) Three bladed propeller (on TWIN 503 only)
This propeller made of composite materials attenuates the engine vibrations and allows a
decrease in fuel consumption. It is adjustable from the ground. Set the recommended value
of 13 ° is for current use. This propeller does not lead to any modifications in the aircraft
behavior. One should never use it with a rotation speed over 2900 rpm. Its fitting does not
change the empty weight of the trike.
2) Three points safety belt
This option gives better occupant protection in case of major accidents or sudden shocks.
Do not unbuckle your belt carelessly (keep the buckle in hand while unfastening) as the
buckle could strike the propeller. The 3 points safety belt whole device reduces the useful
load of the TWIN trike by 3.5 lbs (1.5 kg).
3) Parachute
Trikes can be equipped with a pyrotechnic rocket parachute fixed under the engine. It can
be integrated into the luggage compartment, if installed; a special cut allows its launching.
To deploy the parachute, pull the red handle placed between the pilot's legs, on the seat
frame. The parachute will allow the occupants and the aircraft to descent safely if a major
problem occurs (collision, flight envelope exceeded). If altitude allows, switch the engine
off before deploying parachute. If not, the engine will be stopped at the same time you
pull the handle, due to the additional switch located on the handle fitting. Always inspect
bridle connection points and activation cables before flying. WARNING: do not modify
them.
When rigging the wing, wires must be fixed with the link shackle.
The parachute does not change the flight behavior of the microlight but its weight reduces
the useful load by 22 lbs (10 kg).
4) Dual control for instruction
This option allows for control of the ground steering and the engine power from the rear
seat. For instructors, it allows full control from the rear seat of the aircraft. It reduces the
useful load of the TWIN trikes by 2.2 lbs (1 kg).
5) Towing system
The towing system reduces by 2.2 lbs (1 kg) the useful load of the GTE trikes.
It allows streamers, advertising signs and hang glider towing.
Pulling the lever, set in the left lower part of the frame seat, backward releases the towing
cable.
6) Three instruments panel
This case fastened onto the trike lower beam allows 3 engine control instruments fitting.
TWIN models equipped as such have a useful load decreased by 1 lb (0.5 kg)
