1. A ducted fan VTOL vehicle comprising:

  • a thrust-generating system of plural controlled ducted air movement units having controlled propellers or fans located within respective ducts and having means capable of generating independent forces and moments in any of six fundamental degrees of freedom while operating within at least some part of a flight envelope, said six degrees of freedom comprising linear movements of the vehicle Vx, Vy, Vz and angular movements of the vehicle ω

    x, ω

    y, ω

    z along the axes x, y, z wherein each movement may be independently controlled;

    a system of pilot initiated input transducers M1-Mn coupled to pilot initiated control actuators accessible to a pilot'"'"'s position in the vehicle and producing controlled outputs corresponding to pilot initiated inputs, at least some of said transducers M1-Mn being coupled to primary pilot initiated flight control actuators, said primary pilot initiated flight control actuators being those actuators that, if active, require substantially continuous pilot attention and control inputs for maintaining primary control of vehicular movement;

    autopilot and flight control systems configured to provide output flight control signals controlling physical parameters of the thrust-generating system in response to input signals;

    said control systems being connected to said system of pilot initiated input transducers and adapted to control physical parameters of the thrust-generating system in response to outputs of selected ones of the pilot initiated input transducers and in response to additional vehicle transducers;

    wherein said control systems are configured, while operating in said at least some part of a flight envelope, to utilize four or less primary pilot initiated flight control actuators for primary control of the vehicle while also automatically controlling all said six independent degree(s) of freedom in vehicular movement.
