1. 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; andimplementing the take-off procedure upon take-off. 2. The method according to claim 1, wherein each of the plurality of optimized take-off parameters are selected from the group consisting of a take-off speed, a thrust reducing altitude, an intermediate thrust speed, an acceleration altitude, an intermediate speed, and an altitude indicating an end of a take-off procedure. 3. The method according to claim 1, wherein each of the plurality of reference take-off conditions are selected from the group consisting of an airport characteristic, a pilot-selected aircraft characteristic, a condition imposed by air control authorities. 4. The method according to claim 1, wherein each of the plurality of take-off criteria are selected from the group consisting of a pollutant emission under a predetermined altitude, noise at a predetermined distance of a runway used for take-off, an average noise around an airport, an acoustic footprint at ground level, a use duration of a take-off speed, an ascent duration up to an ascent end, and a quantity of fuel consumed.
