Break
Drum brake at front and disks at rear.

Light
Forward position lamps - in the side wheel covers
(LED type) – 20 m visibility. Handy at landing in dark.

                             Instruments









Operation time counter - measures in hours.

Altimeter – measuring the barometric pressure for
altitude.
Tachometer - RPM, measures the revolution speed of
the engine.

Air Speed Indicator (IAS) - measures the aircraft's
travelling speed relative to the surrounding air  using a
venturi system. This is not the ground speed. Critical at
landing and take off or compare to the GPS.

Variometer - Vertical Speed Indicators (VSI) measures
the rate of climb or descent in m/s, by barometric
pressure.

Compass - Determine the direction where the Trike is
heading. It is subject to some errors of lag or overshoot.


Exhaust gas temperature gauge (EGT)  - Indicates the
performance of the combustion chamber. High EGT
means lean fuel mixture, a warning for meltdown.

Cylinder head temperature (CHT) gauge – before it
gets too late to fry your engine.

Fuel level indicator - this trike has a 44 litre tank
(normal unleaded).This will provide about 4 hours flight
including half an hour reserve.

Throttle (adjustable with left leg or hand (at front of
seat mount)

Radio - communicate to a tower

GPS - better for direction than compass. Will lead you
to your next spot straight.
BEFORE FLIGHT CHECK PROCEDURE
Mr. Jeno Happ is the owner of this trike. By his name I call it the Jeno Trike.
Mr. Happ introduces what a trike owner may consider before taking off.
1. Inspection

The Trike must be inspected before any flight.

First go around it check visually and physically the fittings and bolts. Keep in mind to follow the factory regulations for all
parts. Check safety pins at place and joints for rust, wear. They cannot be loosely fitted. Check wires for frazzle. Pay
special attention for the joints of the wing to the Trike. Here, the wing must swing to any direction without any hindrance,
should not find any tension at the joints. The connection is guaranteed between the Trike and the wing not only by the
clutch mechanism but by the safety cable. In case when clutch breaks, the cable will still connect wing to Trike (it has a
30cm loose move to catch the cross bar).
I start the safety check
at the noseplate.
Checking the cable
tangs, safety pin at
the joints of the Keel
and Leading Edges.

Then I walk
around the Trike.
When finished begins the engine start up procedure.
Checking the flying wires for its attachments, for
loose or worn out bolts.Checking the position of the
turned wing to the propeller. The minimum distance
is 15cm.
Checking the outrigger
joint of the spreader
bar (traverse spar) to
the Leading Edges
Checking the wing at the
Leading Edges for cuts or
worn out signs
Checking inside at the
end of the Leading Edges
Looking inside of
the wing for
abnormal sings.
Open the zip fastener,
checking the dive stick.
Checking the flying
wires attached to the
King Post.
Checking the battens
Checking the
upper rigging.
Checking the safety pin
at the flying wire and
the King Post.
Visually checking the
wing for cuts or wear from
the leading edge through
the wing platform to the
trailing edge.
Checks the right tubes and right dive stick.
Checking the safety pin
at the control bar's right
side.
Checks the safety pins at the Universal
Joint or hangpoint rocker arm that
connects the wing to the trike.
Checking the safety pin at
the nose strut. Checking
the mast.
Checking the safety pin
at the control bar.
Checking the flyig wires
attachments to the Keel.
Examines the cables to
the spark plugs.
Checking the exhaust
temperature gages.
Taking a look around
the fule pump and the
bottom part of the
engine.
Checking the safety pin
at the control bar's left
side.
Checking the safety
wire of the exhaust
pipe, that connects
broken pipe to
mounting during flyght.
Checking the propeller
for nicks and cracks.
Checking the axle for blatter.
Checking engine
suspension.
Checking the carburetor's
rubber sealing to the
manifold.
Visually checks the cover
of the cooling area.
Visually checking
the draglink and
the wheel.
Visually checking the
Carriage and the fuel tank
(44litre).
Checking the Fuel Gage
The Fuel Tank is under
the seat.
Checking the Choke, on
the seat mount.
The throttle is on the left
of the set mount.
Visually cheks the
throttle pedal (left) and
break pedal (right).
Turning on the GPS.
Checking parameters.
Checking the coolant
temperature gage.
Visually check of the
starter and wirying.
Checking the oil fill and
area.
2. Starting up the Engine

Taking the Trike to such place where the small pebbles, dirt etc, cannot harm people or the Trike while the propeller
rotate.
The Trike must be fixed either with handbrake (if mounted) or with a block. This is not necessary if the pilot is in the seat.
Before start up he pulls the choke for rich fuel mix - this is not necessary at hot start. Then he checks the ignition key if it
is in off position. It must stay in off position on the ground!
It followed by pumping fuel manually using the AC pump, until the closing valve of the carburetor lets it.
The propeller is turned around several (maybe 10 is enough) times, to fill the cylinders with fresh fuel mix. Taking a last
look around to see there is no obstacle nearby the propeller.
Then he warns saying loud “the propeller is free”.
He sits in the Trike, turns on the ignition, until the starter will start up the engine (or he pulls the starter cable, mounted
above the head, until the engine runs).
The engine is warmed up to the working temperature described in the factory manual. This is about a 3000 rpm
(Simonini). When the coolant thermometer or the cylinder thermometer indicates the working temperature, higher
revolution is allowed.
Then the fuel level is checked for the planned flight.
Now the Trike is ready to fly.
3. Take off

Taxiing to the take off line.
Here the pilot make a last visual check of the wing, engine and the instruments. This habit ensures he has not left out
anything from the checklist.

Thers are two more checks:
•        The engine is turned to the highest revolution. Checking for smooth operation.
•        Checking the double ignition. This is done at 4000 rpm. Switching off the cylinders one by one. The Odometer
should not indicate more than 100 rpm difference. Otherwise we pull aside and clean the spark plugs and check the
ignition.


If all is right, he inspect the airspace and takes off.
