The first models will require a pilot's license, but by the time consumers are buying them the high speed flight will only be done under computer control. Manual flight will be slow, and taking a car out of manual mode will make it shed the speed before you get close to anything...because "manual mode" still involves asking the computers to move the thing.

      Flight characteristics

      Autogyros are often regarded by fixed-wing aircraft pilots as "dangerously unstable", which is certainly true if one tries to fly a autogyro using fixed-wing principles. Piloted properly, a autogyro is slightly safer than a fixed-wing aircraft because it cannot stall. A "stall" does not mean an engine-out event, it means a fixed wing aircraft is travelling too slowly for the wings to produce lift. Since the rotor of a autogyro is always spinning, it cannot stall. If forward airspeed becomes zero, the autogyro will slowly drift to the ground, rotor still spinning. A vertical landing in this manner will not critically damage most autogyros.

      One weakness in the autogyro is pitch instability (pitch is the tilting up or down of the craft as viewed from the front or the back). Pitch instability is a problem because autogyros cannot handle negative-gee forces (positive-gee forces push people into their seats; negative-gee forces make people float out of them, such as driving down a steep hill at high speed in an automobile). Negative-gee forces "unload the rotor". A flying autogyro hangs from the rotor much like an object hung from a string. As long as the plane is hanging from the rotor, stability is maintained. The instant zero or negative-gees are introduced, rotor speed begins to decay and the gyroscopic forces stabilizing the plane are lost.

      Negative-gees are usually caused by Pilot-Induced Oscillation, or PIO. PIO happens when a pilot adjusts his pitch too much too quickly, then makes a countering control input to bring the pitch back. The countering input often overcompensates, and the autogyro begins to buck like a bronco. This is most likely at high engine throttle settings. If the pilot continues to fight the plane, the rotor (which is flexible) usually flops down and strikes the spinning propeller, which destroys both and sends the autogyro into an uncontrolled fall. The way to avoid this during an incipient PIO is to apply gentle backpressure on the stick (to raise pitch) and cut engine power. Note that this is the exact opposite of what fixed-wing pilots are trained to do when in trouble, which has lead to some unfortunate accidents and the autogyro's undeserved reputation for being "dangerous".

      Another danger is "bunting over" or a Power Push-Over (PPO). A autogyro's vertical airspeed (climb or sink rate) is directly coupled to airspeed. Increase forward airspeed, increase rate of climb. In order to maintain level flight at high engine throttle settings, the pilot must tilt the rotor forward to translate some of his lift into forward motion. Too much tilt, and the autogyro's overall pitch will aim down towards the ground. When this happens, negative-gees occur, rotor speed drops too low to provide lift, and the autogyro tumbles end-over-end in a sommersault. It is impossible to regain control after a PPO.

      Two factors lead to pitch instability: no or too small horizontal stabilizers (h-stabs) and high thrustline engine placement. A large h-stab, ideally in the prop wash (where the propeller blows on it) will reduce the tendency of a autogyro to over-pitch as a result of improper control input.

      If the engine thrustline in a pusher-type autogyro is high -- meaning the axis of propeller power is above the center of gravity for the aircraft -- the autogyro tends to pitch forward under sudden power application (see PPOs above, as for why this is Bad). (Unfortunately, Benson-type autogyros have a notably high thrustline.) If the thrustline is low, the autogyro tends to pitch up under sudden power application, which is harmless. It's difficult to have a low thrustline without a really tall autogyro (such as a "Dominator" style) however, so most autogyro designs simply try to get the thrustline as low as possible though still being slightly abo

    It can fly like any normal plane with only two of the eight engines operational. It doesn't have to VTOL; it can take off or land in the normal fashion. Since the engines are not mechanically linked in the normal sense, it would take a catastrophic failure to lose more than a few engines.
