CAUTION
Use of automotive gasoline containing alcohol (e.g.: methanol or
ethanol) other than specified in the above listed specifications, is not
permitted.
Petroleum suppliers provide automotive gasoline of varying volatilities, depending on the
season and climatic zone. Fuels with higher volatility (“cold weather” grade fuels) are
more susceptible to fuel vapour formation than fuels with lower volatility (“hot weather”
grade fuels), at equal temperatures. Use of fuels dispensed in winter or in colder climatic
zones, under high ambient temperature conditions, increases the risk of vapor formation
and subsequent possible engine malfunction.

1.9. LUBRICANT AND COOLANT
1.9.1. Lubricant
Use only motor oil with API classification SF or SG or higher.
Due to high stresses in the reduction gears, a 4 stroke motorcycle oil of a registered brand with gear additives
that meets API classification SF or SG are highly recommended.
The viscosity should be selected according to the various climatic conditions using the following table.

1.9.2. Coolant
EVANS NPG+ waterless coolant or a comparable coolant must be used without water or other
additives.
WARNING
Water or water-containing coolant must not be added in any case to the cooling system.
CAUTION
The coolant manufacturer’s data for change/replacement, usage, and operation are to be
observed.

NOTE
The level in the reservoir can be checked using the coolant dipstick. Excessive overfilling
of the reservoir can result in overflow during operation. In the event of a completely empty
reservoir, the coolant level in the dispatcher vessel on top of the engine must also be
checked.

2.1. INTRODUCTION
Chapter 2 of this Flight Manual comprises the operating limitations, instrument markings, airspeed
indicator markings, and the limitation placards which are necessary for the safe operation of the airplane,
its engine, and standard systems and equipment.
The operating limitations in this Chapter and Chapter 9 have been approved by the Department of
Transport (DOT), and must be complied with for all operations.
These limitations must be complied with for all operations.

Maximum : 5.8 psi (0.40 bar)
(f) Oil Temperature
Minimum : 122°F ( 50°C)
Maximum : 266°F (130°C)
: 12 psi (.8 bar) Below 1440 RPM
: 29 psi – 73 psi (2.0-5.0 bar) Above 1440 RPM

2.7. WEIGHT
Maximum permissible weight : 750 kg (1653 lbs)
Maximum permissible weight in the baggage
compartment
: 20 kg (44 lbs)
only permissible with baggage harness
WARNING
Exceeding the weight limitations may lead to overloading of the airplane, as well as
degrading of the handling characteristics and flight performance.
2.8. CENTER OF GRAVITY
The reference datum (RD) for the center of gravity (CG) calculation is tangent to the leading edge of the
wing at the root rib. This plane is vertical when the fuselage is horizontal. Procedures for horizontal
alignment, as well as particulars with regard to the empty weight center of gravity, refer to Chapter 6.
Most forward CG (all weights) : 250 mm (9.84 in) aft of RD
Most rearward CG (all weights) : 390 mm (15.35 in) aft of RD
WARNING
Exceeding the center of gravity limitations reduces the maneuverability and stability of
the airplane.
The procedure used to determine the center of gravity is described in Chapter 6.

2.9. APPROVED MANEUVRES
This airplane is certified in the NORMAL Category in accordance with JAR-VLA.
Permissible Normal Category Maneuvres:
a) All normal flight maneuvres
b) Stalls (except WHIP stalls)
c) Lazy Eight’s Entry speed: 116 kts (215 km/h)
Chandelles: Entry speed: 116 kts (215 km/h)
Steep turns in which the angle of bank does not exceed 60°
NOTE
Aerobatics are prohibited.
2.10. MANEUVERING LOAD FACTORS
Table of structural maximum permissible load factors:
Positive + 4.4 + 4.4 + 2.0
Negative - 2.2 - 2.2 0
at vA: at vNE: with fully
extended flaps
WARNING
Exceeding the maximum load factors will result in overstressing of the airplane.
Simultaneous full deflection of more than one control surface can result in overstressing
of the structure, even at speeds below the maneuvering speed.
