A method for operating an aircraft having multiple drive units including: a) providing a first flight control unit (CTRL-1), which activates the drive units according to a first control implementation when CTRL-1 is active; b) providing a second flight control unit (CTRL-2), which activates the drive units according to a second control implementation when CTRL-2 is active; c) continuously monitoring a function of the currently active flight control unit (CTRL-1); d) changing the active flight control unit from the currently active flight control unit (CTRL-1) to the newly active flight control unit (CTRL-2) in dependence on a result of the monitoring in step c); in which the change in step d) for the newly active flight control unit (CTRL-2) includes: d1) initializing starting values of a movement equation of the aircraft implemented in CTRL-2 using currently known state values (x) of the aircraft; d2) initializing integrators of CTRL-2 using control commands for the drive units from CTRL-1; d3) difference equalization between control commands (u1) for the drive units from CTRL-2 and control commands (u2) for the drive units from CTRL-2.
