8.3 Ground Handling
Experience shows that aircraft may be exposed to much higher loads when operated on
ground, than when in flight.
Take care not to impose high loads caused by excessive and fast taxying on rough terrain,
or hard bouncing of the aircraft over the hangar thresholds etc.
Use caution when handling the gyroplane on ground. Do not push hard at the rudder or at
the outer stabilizers. Avoid excessive swing of the rotor blades as repeated bending
ultimately leads to fatigue or damage.
8.4 Cleaning
Care and regular cleaning of engine, propeller, rotor system and fuselage is the basic
foundation for airworthiness and reliability. Therefore, the gyroplane should be cleaned after
every last flight of the day or more often, if environmental conditions dictate.
In order to protect the gyroplane against dirt, dust, bird soil, and sunlight, the aircraft should
be covered with the Autogyro covers or a light plastic tarpaulin or cloth (use a clean, lint
free, cloth for the canopy). Openings to the engine, service access port and airspeed
indicator should be closed after the flight (to limit access for insects, birds etc.).
Contamination can be cleaned with clean water, possibly with mild cleaning additives. To
clean the rotor it is best to soak contamination with a cloth or towel, wipe with soft or micro-
fibre cloth, and rinse thoroughly with water.
A clean canopy aids safe flying. Clean with fresh water for removal of grit etc, without
rubbing the grit into the canopy surface. Then use proper plexiglass cleaning sprays such
as Plexus with soft lint free cloths to polish and finish the surface inside and out. Read and
follow the product instructions.
A good quality polish helps protect the surface finish and reduce surface friction.
Use of RainX or other proprietary rain repellent compound will help rain drops wash away
when flying in rain. Read the instructions, and ensure the compound is suitable for use on
Plexiglass. It is recommended to check that it does not affect the canopy by applying to a
small rearwards area first and checking for any negative reaction.
CAUTION
Do not use gasoline or solvents as cleaning agents for the windshields, as it
will destroy them irreparably. Do not let windshields sun-dry after washing as
they will stain permanently.
8.5 Refuelling
Have aircraft electrically grounded before refuelling by attaching the earth (ground) lead to
the engine exhaust pipe. Be aware that most airfield refuelling equipment is laid out for
larger diameter tank filler necks and high flow rates. To avoid contamination, use a funnel
with strainer and/or filter when refuelling from canisters. In order to top-off both tanks allow
flow levels to balance-out.
