1.1 Introduction
This manual is designed as an operating guide for pilots, instructors, and owners/operators,
providing information for the safe and efficient operation of this gyroplane. It includes
material required to be furnished to the pilot by the competent certification authority. This
handbook is not designed as a substitute for adequate and competent flight instruction,
however.
Pilots of this aircraft must hold a proper license including the class rating ‘gyroplane’,
corresponding to the aircraft’s registration. A special endorsement may be required to fly
with passengers. It is the pilot’s responsibility to be familiar with this handbook, the special
characteristics of this gyroplane, and all other information and legal requirements relevant
for the operation in his country. The pilot is responsible to determine the gyroplane is safe
for flight, and to operate the aircraft with respect to the procedures and limitations provided
in this manual.
It is the owner’s/operator’s responsibility to have this gyroplane registered and insured,
according to country-specific regulations. The aircraft owner/operator is also responsible for
maintaining the gyroplane in airworthy condition. Maintenance instructions are provided in
the Maintenance Manual and in SECTION 8 of this manual. Note that depending on the
kind of operation, type of maintenance activity, or component involved, the competent
authority may dictate qualified personnel and/or respective facilities.
1.2 Certification
The Cavalon is designed, tested and approved according to the German design
specifications for microlight gyroplanes (“Bauvorschriften für Ultraleichte Tragschrauber”,
BUT 2001) including its latest amendment published in “Nachrichten für Luftfahrer” NfL II
13/09 issued 12.02.2009, as well as the British Civil Airworthiness Requirements (BCAR)
Section T issue 4.
The corresponding certification documents (Geräte-Kennblatt) have been issued by the
responsible Germany department DULV (Deutscher Ultraleichtflugverband e.V.),
respectively the German national certifying authority.
AUTHORITY FOR FLIGHT WITHIN THE UK
The legal basis for the operation of this CAVALON autogyro is regulated in the
Airworthiness Approval Notification (AAN29345), issued by the UK Civil Aviation Authority
(CAA). It has been shown to comply with the requirements of BCAR Section T issue 4, and
is considered as a factory built aircraft. Reference must be made the Permit to Fly
limitations issued by the CAA for each individual aircraft.
The noise certificate was granted according to the German requirements for noise
protection for microlight gyroplanes (“Lärmschutzverordnung für Ultraleichte
Tragschrauber”).
1.3 Performance Data and Operating Procedures
The legal basis for operating a gyroplane is provided by national law and its respective
regulations. The instructions and conditions contained have to be considered when
operating the gyroplane.

1.4 Definition of Terms
This manual uses WARNINGs, CAUTIONs and NOTEs in bold capital letters to indicate
especially critical and important instructions. Additionally, the colour of the panel (red,
yellow, and grey shading) highlights the significance of the instruction. Definitions for each
term are given below.
WARNING
A warning means that the neglect of the appropriate procedure or condition
could result in personal injury or loss of life.
CAUTION
A caution means that the neglect of the appropriate procedure or condition
could result in damage to or destruction of equipment.
NOTE
A note stresses the attention for a special circumstance, which is essential to
emphasize.
1.5 Important Note
Before each flight pilots must make themselves familiar with the appropriate navigational,
weather and safety information pertinent to their planned route.
The limitations provided in SECTION 2 of this manual must be respected at all times. Check
the manufacturer’s web site www.rotorsport.org regularly for flight manual updates,
airworthiness directives, service bulletins, or safety information.
Abrupt manoeuvres or flight in heavy turbulence must be avoided as this could lead to rotor
speed variations associated with high stress, possible damage to the aircraft, or
uncontrollable attitudes.
