Method and device for optimizing a takeoff procedure of an aircraft

A method for optimizing a take-off procedure of an aircraft, wherein the take-off procedure comprises a plurality of take-off parameters, the method comprising:

• receiving, via a processor on-board the aircraft, a plurality of reference take-off conditions, wherein each of the plurality of reference take-off conditions are input by an operator of the aircraft;
• determining, via a processor on-board the aircraft, a plurality of sets, wherein each of the plurality of sets comprises at least one of the plurality of reference take-off conditions and a plurality of take-off criteria for the aircraft;
• receiving, via a processor on-board the aircraft, a cost for each take-off criteria in each of the plurality of sets;
• creating, via a processor on-board the aircraft, a selected set from the plurality of sets, wherein the selected set minimizes a total cost associated with the selected set, wherein the total cost is a sum of the cost for each take-off criteria in each of the plurality of sets;
• receiving, via a processor on-board the aircraft, a plurality of actual take-off conditions, wherein each of the plurality of reference take-off conditions are input by the operator of the aircraft immediately prior to a take-off procedure, such that the plurality of actual take-off conditions represent current take-off conditions and may be the same as or different from the plurality of reference take-off conditions;
• converting, via a processor on-board the aircraft, the selected set into an optimum set comprising a plurality of optimized take-off parameters, wherein each optimized take off parameter is given by the expression:
• X=Xref+dXref/dp(p−pref)
• wherein Xref represents a member of the selected set,
• wherein pref represents a reference take-off condition,
• wherein p represents an actual take-off condition;
• defining a take-off procedure based on the optimum set;
• and
• implementing the take-off procedure upon take-off.
