TECHNICAL DESCRIPTION, OPERATING, MAINTENANCE AND REPAIR MANUAL
Table list of Circuit breakers
According to a customer’s desire a protection of some consumers can be provided by
the install of ETA breakers type.
The electric starter switch is a keylock type.
At additional installation of the instruments by the owner is necessary to take account to
the weight limitation and C.G. of the ultra light aircraft and to the electromagnetic
equipment compatibility. A magnetic field may be changed after an additional
installation of the instruments, whereupon a compass compensation must be done.
1.6.12 Pitot – static system
The Pitot static head serving to read dynamic and static air pressure is located on the
right wing leading edge. Pressure distribution to individual instruments on the
instrument panel in the cockpit is done through flexible plastic hoses.
Take care of the hoses from the Pitot-static tube at the rigging of the wings. They must
not be twisted and the hose coupling must be properly inserted. The static pressure
receivers ( small holes with diameter 1 mm ) are located on the both sides of the
fuselage at distance 0,5 m behind a cockpit canopy frame. Keep the system clear and
without leakage to assure its right function.
Take care of these holes at the aeroplane washing, they must be without a water and
clean. In case that water is inside the system disconnect the hoses from the instrument
and bow into the Pitotstatic head.
WARNING
Avoid the blowing into the Pitot static system before a instrument
disconnection from system. It may cause any instruments damage..
1.6.13 Cable Retractor Winch with Guillotine
The winch serves to retract the tow rope.
System consit from the drum which directly actuated by 12V electromotor, guillotine which
takes all the loads form tow rope, the rope guides and drum electromotor control.. In the
system there are two stops, which make the limits of rope movement id in/out wards.
The rope is heaved in drum placed in baggeage compartment and leads from the drum
through guillotine and carbon tube into the end cone. The rope is puuled out with helper who
grab the end rings which will be engaged to the glider. Rope diameter is 6 mm and max.
length is 50 m. The rope is delivered by winch manufacturer. The stop in out direction is
made by knot on the rope which is covered in original cover. The cover box enters into the
guillotine and stops there.
The heaving works like the pilot turn on the switch on instrument panel. The heaving is
signalised by red annunciator o the switch. The shutting off is automatic when the rope end
with weak link gets on the stop in end cone. The moment when rope gets into the stops is
attended by clik/clack noise, what also serves as acustic signalisation for pilot.
To avoid penetration of foreign matters into the system is all half of baggeage compartment
secured with cover.
