Gyroplanes
I am a gyroplane pilot (UK PPL(G))
1. There are two words in English to describe this type of aircraft .. "gyroplane" and "autogyro". "Gyrocopter" is the name for a particular brand of gyroplane. The MT03 is not of that brand, so it is not a gyrocopter.
2. In the UK the custom is to taxi with the rotors turning at around 50-80rpm, thereby using rotor lift to relieve the loads on the rotor-head arising from taxi-ing on the generally rough surfaces where gyroplanes operate. (Take-off is around 250-280rpm depending on take-off weight.) In France, where I live and fly, gyroplanes taxi to the holding point with stationery rotors. The French accept the rotor loads, but prefer the increased safety of stationery rotors while taxi-ing.
3. It's beginning to look as though the MT03 was stationery in this incident. However, when taxi-ing the control column is held fully forward, to minimise the possibility of striking the fin. Even so, the rotor disk is still angled rearwards somewhat making a collision between a person in front and the turning rotors highly unlikely.
4. With a pusher gyroplane, like the MT03, the main wheels are generally roughly in line with the prop gear-box, with engine in front and the propellor behind the main wheels .. for C of G reasons.
5. As someone else has noted, a Rotax stops very quickly .. usually just a few blades. The main rotor takes ages to stop even with the use of a rotor brake.
