Claim 16:
17. A method for operating an air vehicle, the air vehicle being as defined in claim 1, and comprising operating the air vehicle for VTOL take off, the method comprising the following steps:
(a) vectored thrust climb step, including:
operating the propulsion system in vectored thrust mode to cause the air vehicle to lift off and climb from a surface using vertical thrust generated by the propulsion system;
concurrently operating the set of second propulsion units to exclusively provide stability and control to the air vehicle;

(b) transition step, including operating the set of second propulsion units to provide a forward speed to the air vehicle and concurrently transition the air vehicle from vectored thrust flight mode to powered aerodynamic flight mode;
(c) aerodynamic flight step, including:
operating the set of second propulsion units to exclusively provide propulsion for powered aerodynamic flight mode.
