1.1. INTRODUCTION
The Airplane Flight Manual has been prepared to provide pilots and instructors with information
for the safe and efficient operation of this airplane.
This Manual includes the material required to be furnished to the pilot by JAR-VLA. It also
contains supplemental data supplied by the airplane manufacturer which can be useful to the
pilot.
The Flight Manual conforms to the actual version of the customer's airplane. Any optional
equipment installed on request of the customer (COM, NAV, etc.) is not considered.
For the operation of optional equipment the Operation Manual of the respective vendor must be
used.
For permissible accessories refer to the equipment list, Section 6.5.
1.2. CERTIFICATION BASIS
The basic version of the DV 20 had been approved by the Austrian Federal Office for Civil
Aviation (BAZ, now ACG) in accordance with the Joint Aviation Requirements for Very Light
Airplane (JAR-VLA), issued April 26, 1990, including Amendment VLN92 /1. (Type Certificate No .
FZ 1/93).
The alteration to the DV 20 KATANA 100, with Rotax 912 S3 engine, has been approved by
Austro Control GmbH (ACG) on basis of the JAR-VLA, issue April 26, 1990, according to
CRI A-1 .

1.9. LUBRICANT AND COOLANT
1.9.1. LUBRICANT
Use only motorcycle oil of a registered brand with gear additives.
Use only oil with API-classification "SF" or "SG".
CAUTION
Do not use aviation lubricant!
General
Due to high stress in the reduction gears, oils with gear additives such as high performance
motor cycle oils are required. Because ofthe incorporated friction clutch, oils with friction modifier
additives are unsuitable
as this could result in a slipping clutch during normal operation. Heavy
duty 4-stroke motor cycle oils meet all the requirements. These oils are usually no mineral oils
but semi-or fully-synthetic oils.
Oils primarily used for Diesel engines are generally unsuitable due to insufficient high-
temperature properties and additives which favour clutch-slipping.
CAUTION
If the engine is run on AVGAS 100 LL, the following maintenance
work is required every 50 hours of operation:
Oil Capacity:
oil filter change
oil change
oil level check
Furthermore
avoid continuous use of carburetor heat and
avoid running engine
on idle longer than necessary.
Minimum : 2.0 liters
(2.1 US qt.)
Maximum : 3.0 liters (3 .2 US qt.)

1.9.2. COOLANT
Ensure that only automotive antifreeze solution designed for aluminum engines is used (e .g.
BASF Glysantin Antikorrosion).
CAUTION
Use of low quality coolants may result in sediments within the cooling
system and partial occlusion of lines, degrading the
eff iciency of the
cooling system.
Mixing ratio:
SO to 60% antifreeze concentrate with additives against corrosion mixed with 40 to SO % pure
water shall be used, or alternatively
an equivalently premixed coolant.
NOTE
If problems are encountered with boiling after engine stop gradually
increase the percentage of antifreeze concentrate.
At temperatures below
-1S °C (S OF) a mix1ure of approximately 20% pure water to 80%
antifreeze concentrate should be used to attain a very low freezing point.
In all cases the mixing ratio has to comply wi th the manufacturer's recommendations.
