A method for operating an aircraft with N>4 drive units. A flight control system (FCS) generates control commands u_COM, u_COM∈U∈R{circumflex over ( )}N, for the drive units, via a first channel. u represents limitations of the drive units. The FCS generates pseudo-control commands γ_COM, γ_COMER{circumflex over ( )}4, in the first channel, which specify torques about corresponding axes of rotation of the aircraft and a thrust, a control matrix M∈R{circumflex over ( )}(4×N) with γ=M u establishing a relationship with the control commands u; in the first channel. Admissible control commands u_COM∈U are calculated from the pseudo-control commands; and the first channel is monitored and, based on a result, is passivated. Monitoring takes place in a second channel, pseudo-control commands γ_MON, γ_MON∈R{circumflex over ( )}4, are generated in the second channel and the control commands u_COM of the first channel are evaluated in the second channel using γ{circumflex over ( )}*=M u_COM, and γ{circumflex over ( )}* and γ_MON are compared. A FCS and aircraft are also provided.
