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. 2.1 General WARNING The operation of a gyroplane demands professional pilot instruction and dedicated training on gyroplanes. The aircraft must only be flown by a properly qualified and licensed pilot. WARNING Positive G load on the rotor must be maintained during all flight manoeuvres. Do not perform any manoeuvres resulting in the sensation of feeling light or near weightless. WARNING Smoking on board is prohibited! CAUTION This gyroplane has been designed and tested for a safe design load of 3.0g at maximum take-off weight 560kg. Note that flying at high speeds in turbulent air, especially in combination with aggressive manoeuvres or a steep turn, can easily create high loads on the aircraft. NOTE The certification of this aircraft may limit operations to a specific nation. If the aircraft is to be flown on an international basis, it is the pilot/operators responsibility to ensure that international flight is undertaken in accordance with the laws of applicable national airspace. Pilot Operating Handbook Calidus 915iS/916iS SECTION 2 LIMITATIONS AutoGyro_POH_Calidus 915/916iS Revision 1.2 – Issue Date 01.DEC.2024 2-2 NOTE Whilst this aircraft has been proven compliant to multiple national stringent loading requirements, it may be exposed to unpredictable and high loads in service especially when operated on rough surfaces, such as unprepared grass strips. In these cases it is essential to perform a thorough pre-flight inspection and have components and parts replaced, where needed. NOTE The selection and use of this particular aircraft is at the sole discretion and responsibility of the pilot/operator. The pilot/operator is reminded that the aircraft use may be restricted by the terms of the aircraft Type Certificate or Type Approval operational limitations. AutoGyro Certification Ltd and AutoGyro GmbH take no responsibility for your decision to fly. Because, at the time of writing, no internationally agreed standards exist for gyroplanes, this aircraft has not been certified to that level. Whilst the manufacturer takes great care to ensure the parts are of appropriate quality, the component and system reliability level may be less than that with a Standard Category Type Certified aircraft, and pilot operators must consider this in their flight planning In common with other aircraft of this type, Calidus utilises a non-certified engine. This means that there may be a higher risk of engine failure than if flying with certified engine, with the associated risks of damage or injury as the result of an unplanned landing. Therefore strict compliance with the engine manufacturer9s maintenance schedules, operational procedures and any additional instructions which may be given to you by AutoGyro GmbH, on behalf of the engine supplier, is essential. Aircraft must always be flown with the risk of engine failure in mind, and appropriate precautions taken. 2.2 Environmental Limitations Maximum wind speed or gust intensity ....................................................... 40 kts Maximum demonstrated crosswind component for take-off and landing .... 20 kts Maximum tailwind component for take-off and landing ................................. 5 kts Maximum demonstrated operating altitude ............................................ 12,000 ft Demonstrated OAT for safe operation .......................................... - 20 to + 40 °C 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 strike. If, despite proper flight planning, a thunderstorm should be encountered, consider a precautionary landing to avoid the squall line. A lightning strike may damage the main rotor bearing. Thorough inspection and maintenance after lightning strike must be performed. Pilot Operating Handbook Calidus 915iS/916iS SECTION 2 LIMITATIONS AutoGyro_POH_Calidus 915/916iS Revision 1.2 – Issue Date 01.DEC.2024 2-3 CAUTION Care must be used operating at high altitudes, as it is possible to overspeed the engine in level flight at max power, especially with a fixed pitch propeller. Take care to monitor the engine rpm gauge. Aircraft and engine performance degrades with decreasing pressure altitude and increasing temperatures. Care must be taken to maintain safe flight when nearing operational temperature and pressure extremes. 2.3 Colour Code for Instrument Markings Red Operating limits. Pointer should not enter red during normal operation Yellow Precautionary or special operating procedure range Green Normal operating range Pilot Operating Handbook Calidus 915iS/916iS SECTION 2 LIMITATIONS AutoGyro_POH_Calidus 915/916iS Revision 1.2 – Issue Date 01.DEC.2024 2-4 2.4 Airspeed Limitations and Instrument Markings Air Speed Marking VNE Never Exceed Speed Red radial 225 km/h 140 mph 120 KIAS VB (max design speed for strong gusty conditions) Yellow arc 130 – 225 km/h 80 – 140 mph 70 – 120 KIAS Recommended manoeuvring speed range Green arc 30 – 130 km/h 20 – 80 mph 15 – 70 KIAS VMIN Minimum Speed Yellow arc 0 – 30 km/h 0 – 20 mph 0 – 15 KIAS WARNING The maximum speed VNE must never be exceeded!
