Aerosoft Wilga X Operating Instructions
Aerosoft Wilga X 1.00 Manual
INTROD U C TION
The PZL-104 was developed by the
Development Design Office of the PZL factory
(Poland). It was designed to be a sturdy and
simple aircraft able to operate from small
unpaved runways. The high wing has
additional lift surfaces so it is a real STOL
(Short Take-Off and Landing) aircraft that can
fly at very low speeds and has very gentle
stall characteristics.
The pilot and navigator were placed next to
each other to make communication easier.
This also makes the Wilga a very good training aircraft. So many years after it was designed many are still in
use all over the world to two gliders or to take parachutist to drop altitude.
In many ways this is a real eastern European aircraft. It lacks many of the niceties that the mostly US aircraft
made during the same period and it also has
some quirky features like a starting system
that uses compressed air. Unlike some aircraft
that can be flown with two fingers the Wilga
needs two hands. Many of the controls are
large and rather cumbersome but that’s one of
the charms of the Wilga. They might not be
very refined but the do work and in fact they
work very well and reliable.
When you take your first flight in the Wilga
you are in for a shock. The engine is very large
and very loud. The Wilga shakes as the engine
warms up (that does take a while) and there is a distinct smell of avgas and oil in the cockpit (you can add oil in
flight!). You won’t see much other than the sky as the large engine and massive propeller cause the tail
wheeled aircraft to be tilted backward a lot. With the warmed engine the aircraft is ready to take-off. You
need to keep a good eye on the temperatures
as it overheats easy as you taxi to the runway.
At take-off power it seems like the engine will
explode, noise levels are incredible and it
seems bits will fly off. It’s hard to keep straight
at low speeds without tail wheel steering. But
after a very small run the aircraft transforms
itself from a lumbering beast to a rather
nimble aircraft. The flying characteristics are
docile and it never seems out to surprise you.
As long as you convert enough noise to speed
it will fly very stable. Landing is a non-event as
long as you keep the speed in mind. Throttle back and the massive drag and weight slows the Wilga down very
fast.

CONS T R U C T I ON
The PZL-104 I has a high mounted wing that includes slot flap drooped aileron and fixed wing slats. The
fuselage is made up from a semi-monocoque metal frame with partially fabric covered panels. The power plant
consists of the redial reciprocating air-cooled engine АI-14RA with two-blade rotor controllable pitch US -
122000. The twin fuel tanks are in the wings. The cockpit is closed, four-passenger, with dual control, has the
big glass areas for better visibility and has two removable doors. Equipment differs but most aircraft are
equipped with basic navigation and communication radios.

AIRCRA F T S Y STEMS
OIL S YSTEM
The oil system is used for lubrication, cooling and is used by the propeller control mechanism. It consists of oil
tank, oil filter, oil cooler (with a louvers air flow control mechanism controlled by a turn knob in the cockpit),
engine driven oil pump and a cockpit indication for the oil pressure and oil temperature. Proper use of the oil
cooler is important and oil temperature should be monitored closely. It is important that oil cooling and engine
air cooling should be used together and not working against each other.
FUE L SYSTEM
The fuel system provides the engine with fuel and consists of two wing mounted tanks (each with a fuel level
indicator), hand operated primer pump, fuel selector switch, small feeder tank and a fuel filter. The primer
pump is used to prime the engine with fuel if it has been off for some time. Normally 3 pulls are enough. When
the engine runs the primer pump should be locked (turned horizontal). When total fuel load is below 30 liter
the fuel selector has to be at L/R to ensure a reliable fuel flow. The Wilga will use around 55 l/h in cruise.
HYD R A ULIC SYSTEM
The hydraulic system of the Wilga is very basic and only serves to operate the two (independent) wheel
brakes. It’s a fully closed system without any pressurization.
PNE U M ATIC SYSTEM
The pneumatic system is used to start the engine and consists of two pressure vessels, a main control with
manometer, air and condense filters and a small engine driven compressor. The system can be pressurized on
the ground with a standard compressor (up to 50 kp/cm²) and will be pressurized in flight by the engine driven
compressor.
ELEC T R ICAL SYSTEM
The electrical system is used to provide instruments, radios and engine ignition system with power. It consists
of a 24,5 volt battery, engine driven generator and an electrical bus divided in 12 separate sections, each
protected by a fuse.
RAD I O
Mounted in the main panel is the R-860 transceiver for the 118.0 - 135.9 MHz frequency range. It’s a basic
radio set with an expected range of 100 km. Operation is simple, after switching the system on and waiting 2
minutes the frequency can be set with the MHz and KHz controls. The system is connected to the on-board
communication system that activated with a separate switch.
