1) Towing
− The towing line must include a fuse gauged at 80 daN maximum in order to allow an
automatic releasing in case of over-tensioning.
− Release the towing line above a fully clear ground before landing.
− Test systematically the releasing device of the trike before taking-off.
− The ideal speed for towing streamers is 47 mph (75 km/h). In the case of a glider, the speed
should be adapted to its performances. The emergency procedures stated in chapter III e)
remain applicable; the towing must be launched above a fully clear field prior to landing.
Characteristics, listed in the chart in chapter II c) of the concerned wing user's manual,
lessen due to the drag of towing and flying level requires a superior engine power.
Minimum speed and stall speed remain unchanged.
2) Load carriage, survey material, data transmission, photography, video ...
− Install the loads to be carried on the passenger seat. The holding device has to support
efforts up to 9 g forward, 3 g upward et 1,5 g laterally.
− Limit the dimensions of the loads carried to avoid any contact, stress marks or blocking with
the wing structure and particularly with the inferior longitudinal cables.
− Mounting any kind of camera at the tip of the wing is possible up to a maximum weight of
2 kg (4.4 lbs) if you install a counterweight at the extremity of the opposite wing. The inertia
of the wing on its roll axis will increase.
− The emergency procedures stated in chapter III e) remain applicable.
3) Sky jumpers
− The place is always the back seat, such as in normal tandem or "sidesaddle", body
perpendicular to the trike axis.
− Cut the engine before the preparatory step of the jump. You may use the wheel leg gear as a
step.
− A repetition on the ground is absolutely necessary before taking-off.
− The emergency procedures stated in chapter III e) remain applicable.
4) Floats
− Mounting of floats increases considerably the inertia of the trike in roll and yaw and reduces
its performances due to the increase of the total drag.
− The "taxiage" changes from the ground use by several aspects :
The center of gravity is set higher and the leaning surface is not rigid, which involves a
greater sensitiveness to the wind (risk of flipping over). "Pilot" the wings according to the
indications of the flight manual, even more carefully than on the ground.
The lack of brake requires a good management of the speed and you can fully stop only
once the engine is off.
The components used for the structure of the trike are not intended for a use on the sea
owing to the risk of corroding and electrolytic stress due to the saltiness of this
environment.
The emergency procedures stated in chapter III e) remain applicable.
