2.1 Read this before your first flight!
Every pilot has to understand the limitations and specifications of
this light sport glider. The AOI must be read thoroughly. Please pay attention to the pre-flight and daily checks. Maintenance instructions for the
aircraft are given in a separate Maintenance Manual. For maintenance of
the Jabiru engine, emergency parachute system and other installed
equipment refer to the original manufacturer´s manuals.
Flying of U15 Phoenix must be always done with the possibility of a
safe landing due to loss of the engine power.
U15 Phoenix is a VFR aircraft only. Because of cruising speed and
range of U15 Phoenix flight in to vastly different weather patterns and meteorology conditions can occur. The entry in to bad weather with IFR conditions with VFR aircraft is extremely dangerous. As the owner or operator of
an aircraft you are responsible for the safety of your passenger and yourself. Do not attempt to operate U15 Phoenix in any manner that would endanger the aircraft, the occupants or persons on ground.

2.4 Descriptive data
2.4.1 Airplane description
U15 Phoenix is intended for recreational, sport, cross-country and
training. It is not approved for aerobatic operation.
U15 Phoenix is a single engine, carbon airplane with two side-byside seats. The aeroplane is equipped with fixed two main wheel undercarriage with a steerable tail wheel. The fuselage is a carbon shell with carbon/kevlar seats integrated. Safety belts are attached to the seats and to a
shelf intended for putting off lightweight objects (headphones, maps, etc.).
The wing is a monospar construction with a sandwich skin composed of two layers of carbon fiber and special foam. Control surfaces and
empennage is of the same construction.
The airplane is controlled by dual push-pull control system, only
rudder drive is controlled by cable. The ailerons and elevator are controlled
by the control stick located between the pilot's legs (co-pilot's). The rudder
is controlled by the rudder pedals, flaps and spoilers are operated by control levers located between the pilots.

7.7 Other emergencies
7.7.1 Vibration
If vibrations appear:
1. Set engine speed to power setting where the vibrations are the
lowest.
2. Land at the nearest airfield or perform a precautionary landing
according to 3.6.2
7.7.2 Carburetor icing
Carburetor icing mostly occurs when getting into an area of humidity formation. The carburettor icing shows itself through a decrease in engine power and an increase of engine temperatures.
To recover the engine power, the following procedure is recommended:
1. Apply carby heater system
2. Throttle - set for 1/3 power
3. If possible, leave the icing area, and use carby heat during flight
4. Gradually increase the engine power to cruise conditions
after 1-2 minutes.
If you fail to recover the engine power, land at the nearest airfield
(if possible) or depending on circumstance, execute a precaution-
ary landing according to 3.6.2

UU1155 PPhhooeenniixx
9.2 Towing and tie-down instructions
Towing
It is easy to tow the airplane a short distance by holding the blade
root because the empty weight of this aeroplane is relatively low.
Suitable surfaces to hold the airplane airframe are the rear part of
the fuselage before the fin and wing roots..
Caution
Avoid excessive pressure at the airplane airframe - especially
at the wing tips, elevator, rudder, trim etc.
Caution
Handle the propeller by holding the blade root - never the
blade tip! If starting the engine manually - always handle the
Parking
It is advisable to park the airplane inside a hangar or eventually inside other weather proof space (such as a garage) with a stable temperature, good ventilation, low humidity and dust-free environment.
It is necessary to tie-down the airplane when parking outside.
When the plane must be tied-down outdoors for extended periods,
it is advisable to cover the cockpit canopy, and if possible, the entire airplane using a suitable cover.

Tie-down
The airplane is usually tied-down after a flight day or when needed.
This is necessary to protect the aeroplane against possible dam
age caused by wind gusts.
The airplane is equipped with tie-down bolts on the wing tips.
Procedure:
- Check: Fuel valve off, Circuit breakers and Master switch off,
Ignition key off.
- Tie the control stick with the safety harness
- Close and lock cockpit
- Shut all the ventilation windows
- Tie-down the wings to the ground by means of the straps. It is
also necessary to tie-down the fuselage rear (lace a rope
through the fork).
Note
It is advisable to cover cockpit canopy, if possible the whole
airplane, by means of a suitable covering material attached to
the airframe for long term outside parking.
