    Pilot Operating Handbook SECTION 2 Cavalon LIMITATIONS SECTION 2 - LIMITATIONS This section contains operating limitations, instrument markings and basic placards which are required for safe operation of the gyroplane, including its engine, and standard equipment or systems. General WARNING The operation of a gyroplane demands professional pilot instruction and dedicated training on gyroplanes.

  • Page 28: Environmental Limitations

    In common with other aircraft of this type the Cavalon utilises a non-certified engine. This means that there may be a higher risk of engine failure than in a certified aircraft, with the associated risks of damage or injury as the result of an unplanned landing.

  • Page 29: Colour Code For Instrument Markings

    Pilot Operating Handbook SECTION 2 Cavalon LIMITATIONS CAUTION Care must be used operating at high altitudes, as it is possible to overspeed the engine in level flight at max power. Take care to monitor the engine rpm gauge. Aircraft and engine performance degrades with decreasing pressure altitude and increasing temperatures.

    Pilot Operating Handbook SECTION 7 Cavalon SYSTEM DESCRIPTION SECTION 7 - SYSTEM DESCRIPTION Introduction This section contains the description of the gyroplane and its standard systems and equipment. Optional equipment is described in Chapter 9 of this manual. Airframe and Undercarriage The load carrying structure of the gyroplane consists of a composite monocoque occupant enclosure which is connected to the rotor tower and keel tube.

  • Page 104: Rotor System

    Pilot Operating Handbook SECTION 7 Cavalon SYSTEM DESCRIPTION Rotor System The two-bladed, semi-rigid, teetering rotor system comprises high-strength aluminium extruded rotor blades, a hub bar, and a common teeter hinge assembly. The rotor blades feature an aerodynamic profile especially suitable for rotorcraft which, in combination with its relative centre of gravity, provides aerodynamic stability by eliminating negative blade pitching moments and flutter tendency.
  • Page 105 Pilot Operating Handbook SECTION 7 Cavalon SYSTEM DESCRIPTION The LH flight controls must never be restricted by passenger or objects. Passengers must be briefed. Rudder and front wheel control The rudder is connected to adjustable foot pedals with steel cables which are routed through the lower fuselage and inside the keel tube.
  • Page 106 Pilot Operating Handbook SECTION 7 Cavalon SYSTEM DESCRIPTION The rudder is fitted with a trim tab. This is normally biased to the left, and may be adjusted by the operator to trim the aircraft for straight flight at a desired speed, feet off the pedals. Adjusting it to the left will biase the rudder to the right and vice versa.

    Pilot Operating Handbook SECTION 10 Cavalon SAFETY TIPS Flying Low on Fuel Is Dangerous Never intentionally allow the fuel level to become critically low. Although a gyroplane leaves much more options than a fixed wing aircraft and is easier to control during power-off than a helicopter, a forced landing into unknown terrain always poses unnecessary and unpredictable risk with danger to material, health, or life.
