The Annual Safety Review  presents statistics on European and worldwide civil aviation safety. The statistics are grouped according to type of operation, for instance commercial air transport, and aircraft category, such as aeroplanes, helicopters, gliders etc. EASA had access to accident and statistical information collected by the International Civil Aviation Organisation (ICAO). States are required, according to ICAO Annex 13 on Aircraft Accident and Incident Investigation, to report to ICAO information on accidents and serious incidents to aircraft with a maximum certificated take-off mass (MTOM) over 2250 kg. Therefore, most statistics in this review concern aircraft above this mass. In addition to the ICAO data, a request was made to the EASA Member States to obtain light aircraft accident data. Furthermore, data on the operation of aircraft for commercial air transport was obtained from both ICAO and the NLR Air Transport Safety Institute . 
Carter Aviation Technologies, LLC is the aerospace research and development firm that developed and demonstrated Slowed-Rotor/Compound (SR/C™) technology that couples the speed, range and efficiency of an airplane with the vertical takeoff and landing capability of a helicopter along with the unparalleled safety of a high inertia rotor. Whether incorporated into a jump takeoff configuration or a powered rotor variant with continuous hover capability, SR/C technology offers extraordinary cruise efficiencies and quiet operation. Slowing the rotor in flight is the key to this game-changing technology. Operating at 1/3 the usual rpm reduces rotor drag by over a factor of 5 ( more info ). This translates to overall fuel efficiencies that have been validated through flight testing that are – 3 times better than today’s worldwide rotorcraft fleet.
