REV. 0 Aircraft and systems on board
Introduction
Virus 912 SW is a 10.71-meter-wingspan, twoseat
T-tail motorplane made almost entirely of
composite materials. Its low-drag, high-wingmonoplane,
engine-at-the-front construction
makes it efficient even when flying unpowered.
In fact, the propeller can be feathered to
reduce drag even more.
The undercarriage is a tricycle type with two
main, brake equipped, wheels mounted on
struts and a stearable nose wheel.
Virus 912 SW features flaperons, interconnected
flaps and ailerons presented in the same deflecting
surface. Flaps offer 4 settings: neutral,
1 st , 2 nd and the negative position of which none
have any impact on aileron deflections whatsoever.
What is more, individual main flight
control levers make Virus ideal for initial as
well as for advanced flight training. All aileron,
elevator and flap controls are connected to
the cabin controls using self-fitting push-pull
tubes. Rudder deflects via cables. The elevator
trim is mechanical, spring type.
Airbrakes are available as an option, they reduce
the requirements for runways size for
landing and provide for steeper approaches
and expedite descents.
All aircrafts ship with H type safety harness
attached to the fuselage at three mounting
points. Rudder and belonging brake pedals
can be adjusted to suit your size and needs.
Fuel tanks are located inside the wings. Fuel
selector is in the form of two separate valves,
located on the left and right upper wall of the
cabin. Fuel hose connectors are self securing;
this prevents fuel spills when disassembling
the aircraft. The gascolator is located beneath
the lower engine cover. Refuelling can be done
by pouring fuel through the reservoir openings
on top of the wings or by using an electrical
fuel pump instead. Also featured are low-fuel
signal lights on the instrument panel.
All glass surfaces are made of 2 mm anti UV GE
Lexan, which was specially developed not to
shatter or split on impact.
Main wheel brakes are hydraulically driven disc
type. The hydraulic brake fluid used is DOT 3 or
DOT 4. Cabin ventilation is achieved through
special ducts fitted onto glass doors, cabin
heating, however, is provided utilizing of hot
air from the engine.
To enhance aerodynamics even more, every
Virus 912 SW comes equipped with special
wheel fairings and the propeller spinner. The
propeller is variable pitch, the 80 HP version
also has feathering capability.
Electric circuit enables the pilot to test individual
circuit items and to disconnect the entire
wiring but leave the engine running, should
there come to a distress situation. Navigational
(NAV), anti collision (AC) and landing (LDG)
lights are an option. The firewall is enforced by
heat and noise insulation.
Basic instruments come installed with operational
limits pre-designated.
Parachute rescue system is an option.
Optional is the side access door to the cargo
compartment behind the seats.
