8. An aircraft, comprising:
-
an airframe; drive elements configured to drive movements of the airframe; and a computer, including at least one processor, configured to receive flight planning commands and manual commands and to control operations of the drive elements to operate in; first and second stationary modes which are characterized in that the airframe is stationary relative to ground and in which the flight planning commands are accepted but the manual commands are refused, first and second movable modes which are characterized in that the airframe is movable relative to the ground and in which the flight planning commands are refused but the manual commands are accepted, and an enroute mode and first and second special modes in which the manual commands are refused, the computer being further configured to only allow mode transitions directly between a first safe mode and a first manual mode, directly between a second safe mode and a second manual mode, directly between the first safe mode and the second safe mode and directly between the second safe mode and the enroute mode. - View Dependent Claims (9)
