Abstract: Modern flight control systems should be largely automated because of their complexity. A process is disclosed to automatically correct an originally planned aircraft flight after flight-relevant parameters are changed. The process has the following steps: (a) the values of the flight-influencing parameters which determine the planned flight are supplied to a computer and stored therein; (b) when a change occurs, the changed values are also supplied to the computer and compared therein to the stored values; (c) depending on the results of the comparison and on predetermined checking and selection criteria, it is first checked whether the change requires a flight correction, and if that is the case new parameter values for a corrected flight are determined and stored in the computer instead of the previously stored parameter values; (d) the flight correction determined by the new parameter values is initiated; (e) these process steps are repeated whenever necessary every time the parameter values are changed.
