1 GENERAL INFORMATION
SKYLANE v.4 belongs to the category of ultra-light aircraft as defined by the
Czech Civilian Aviation Regulations (specifically described in the Regulations as a
Sport Flying Device). As of the date of the manufacture, the aircraft meets the
standard set forth by the Amateur Aviation Association of the Czech Republic
which, under the Czech law, is responsible for overseeing this category of aircraft.
The aircraft was assigned the following Type certificate: LAA CZ serial number
ULL –04/2009
1.1 NOTES
It is the responsibility of the pilot/operator of the Skylane v.IV aircraft to be familiar
with the contents of this flight manual and any relevant supplements. The manual
provides the information necessary for the safe operation, handling and
maintenance of the aircraft, including operating instructions for the engine,
propeller as well as the ballistic recovery system.
The aircraft is intended for sport and recreational aviation and meets the
requirements of the Czech UL-2 standard. All commercial operations, with the
exception of pilot training, are prohibited.
The aircraft is not equipped with a certified aviation engine or accessories. The
pilot should therefore carefully select the course and altitude of each flight so that
a safe emergency landing can be made in the event of an engine failure.
ATTENTION
This ultra-light aircraft has not been certified by the Czech Civilian Aviation
Authority. All operators of this aircraft assume full responsibility for the
safety of their operations.
1.2 WARNINGS, CAUTIONS, NOTES
The following definitions apply to Warnings, Cautions and Notes:

4. NORMAL PROCEDURES
4.1 PRE-FLIGHT INSPECTION
The pre-flight inspection should be conducted at a minimum before the first flight
of each day or following any maintenance work on the airplane. Incomplete or
care-free pre-flight inspection could result in an accident. The preflight inspection
should be conducted using the checklist contained in this chapter.
NOTE
The phrase „check condition“ refers to a visual check of the surface condition,
checking for damage, deformations, scratches, dents, corrosions or presence of
other irregularities which may negatively affect safety of flight.

than 10 seconds. After each 10 second
period, 1 minute cooling period is necessary to
prevent starter overheating

3)Before starting the engine, ensure that all
avionics (XPD, GPS, and INTERCOM) are off
to prevent damage due to stray currents.
Note: Fuel valve is open when the fuel valve handle is in the
horizontal position; the valve is closed when the handle is in the
UP position.
4.2.3 ENGINE WARMUP AND RUNUP
Engine Run-up
Follow the instructions in your Engine Manual. Before take-off, all engine
parameters must be in their normal operating range.
Engine should be warmed up at 2000 –2500 RPM.

2)The wheels should be secured using chocks.
3) Minimize engine operation on one magneto.
4)Do not conduct the engine run-up over loose
terrain or gravel to prevent propeller damage.
5) To minimize engine vibrations, maintain engine
RPM over 2000 RPM
