component involved, the competent authority may dictate qualified personnel and/or
certified facilities.
1.2 CERTIFICATION
The H3 Sport was designed, tested and certified according to the French design
specifications for ultralight helicopters (Code HUL) including the latest amendment
published on the date of this revision, it has also been designed and tested for
conformity with the British Civil Airworthiness Requirements (BCAR) and CS-VLR,
although these latter two certifications have not been solicited.
The certification document (Fiche d’identification) was issued by the French DGAC
(Direction Générale de l’Aviation Civile).

1.6 DESCRIPTION
The Dynali H3 Sport is an ultralight two-seat helicopter in a side-by-side seating
configuration. The main structure is a stainless steel or painted steel chassis which
frames the engine, the cabin, the tail structure and all the main and rear transmission.
The main rotor mast is made from stainless steel and the main rotor blades are in
extruded aluminum. The rotor head is controlled by push-pull rods through the swash
plate.
The tail structure is composed of an aluminum boom, supported by two carbon tail
struts. The tail rotor blades are formed in carbon and are controlled by push-pull cables.
The cabin cell and the stabilizer are made from vacuum infused carbon fiber and the
canopy is in Perspex.

SECTION 2 - LIMITS IN USE
2.1 GENERAL
This section contains operating limitations, instrument markings and basic placards
which are required for safe operation of the helicopter, including its engine, and
standard equipment or systems.
WARNING !
The operation of a helicopter demands professional pilot instruction and
dedicated training on helicopters. Without valid license, the helicopter must not
be operated.
WARNING !
During the entire flight, adequate rotor loading must be maintained. Do not
perform any manœuvres resulting in the sensation of feeling lightness or near
weightlessness.
WARNING !
Smoking on board is strictly prohibited.
CAUTION
This helicopter has been designed and tested for a safe design load at maximum
gross weight. Flying at high speed in turbulent air, especially in combination
with aggressive manœuvres or a steep turn, can easily create higher loads on
the aircraft.
NOTE
This helicopter does not comply with the terms of the international authority for
civil aviation (ICAO). There is no international common regulatory system for
ultralight helicopters.

17
NOTE
During the certification process, all required safe loads have been successfully
demonstrated with an adequate safety margin. However hard landings or landing
on uneven surfaces may result in excessive loads on certain components.
Following such incident, extra attention should be given during the external pre-
flight check.
2.2 ENVIRONMENTAL LIMITATIONS
Minimum operating Outside Air T° for safe flight ................................ -15 °C
Maximum operating Outside Air T° for safe flight, ............................. +40 °C
Maximum wind speed or gust intensity for safe flight ….................. 60 km/h
Maximum demonstrated crosswind component………… .... 30 km/h (16kts)
Maximum tailwind component for take-off and landing… .... 30 km/h (16kts)
Maximum demonstrated operating altitude……….......................... 10 000 ft
Slope landing ........................................................ 8° longitudinal / 4° lateral
WARNING !
Do not consider flying in the likelihood of severe weather. Thunderstorms may
develop rapidly with the risk of heavy precipitation or hail, severe turbulence
with strong vertical air movements, and lightning strikes. If, despite proper flight
planning, a thunderstorm should be encountered, consider a precautionary
landing immediately.
NOTE
It is the responsibility of the pilot / operator to make the decision if flight
operation is safe.

Yellow zone ................................................................. 131 km/h - 164 km/h
Red zone (VNE)............................................................................. 165 km/h
NOTE
The yellow zone of the air speed starts at 131 km/h although the cruising speed
of the H3 Sport is 140 km/h. This zone points out the speed limit where all the
flight manoeuvres can be safely executed.
WARNING !
The VNE must never be exceeded.

WARNING !
Depending on installed optional equipment, VNE may be lower !
WARNING !
Sudden or large forward input on the controls must be avoided at all means,
even at airspeed within green arc. Do not exceed maximum speed when flying
through turbulence, gusts or rough winds.
CAUTION
Notice the first red zone located between 0 and 85 km/h that shows the
recommended flight profile during take-off and landing. Thus, it is recommended
to have a speed close to 85 km/h when flying lower than 500 ft ASFC.
