1. A process for automatically optimizing on the ground the aerodynamic configuration of an aircraft equipped with wings which are provided with spoilers, wherein, I/ monitoring the aircraft to check whether it is on the ground, and if so, the following operations are performed:II/a) determining the current value of at least one control parameter of the aircraft;b) using at least the current value to determine a criterion; andc) using the criterion and a plurality of predetermined optimum deflection angle commands to determine a current deflection angle command, each of said optimum deflection angle commands relating to the deflection of the spoilers and being optimised to provide the aircraft with an aerodynamic configuration for optimising a particular parameter, wherein the current deflection angle command, when applied to said spoilers, provides the aircraft with an optimum aerodynamic configuration for the current situation of the aircraft,wherein in step II/a), the current value of at least one of the following control parameters is determined: the position of a control stick of the aircraft, which enables a pilot to control the pitch of said aircraft; andthe trim of the aircraft,wherein in step II/c), said current deflection angle command is determined using said criterion and a predetermined curve which shows the deflection angle command as a function of the criterion value, said curve including said optimum Deflection angle commands and transitions between such optimum deflection angle commands. 2. The process according to claim 1, wherein a step II/d) is further carried out, in which said current deflection angle command, determined in step c), is applied to actuators of spoilers of the aircraft. 3. The process according to claim 1, wherein: in step II/a), the current values of at least two control parameters of the aircraft are determined;in step II/b), an individual criterion is determined for each of said current values, and the criterion is derived from the individual criterion thus determined. 4. The process according to claim 1, wherein said transitions are linear. 5. A device for automatically optimizing on the ground the aerodynamic configuration of an aircraft equipped with wings which are provided with spoilers, said device comprising: first means for automatically monitoring the aircraft in order to check whether it is on the ground;second means for automatically determining the current value of at least one control parameter of the aircraft;third means for automatically determining a criterion, using at least such current value; andfourth means for automatically determining a current deflection angle command which, when applied to said spoilers, enables to provide the aircraft with an optimum aerodynamic configuration for the current situation of the aircraft, said fourth means determining said current deflection angle command using this criterion and a plurality of predetermined optimum deflection angle commands, each of said optimum deflection angle commands relating to deflection of the spoilers and being optimised to provide the aircraft with an aerodynamic configuration for optimising a particular parameter, wherein said second means are formed so as to automatically determine the current value of at least one of the following control parameters: the position of a control stick of the aircraft, which enables a pilot to control the pitch of said aircraft; andthe trim of the aircraft, wherein said current deflection angle command is determined using said criterion and a predetermined curve which shows the deflection angle command as a function of the criterion value, said curve including said optimum deflection angle commands and transitions between such optimum deflection angle commands. 6. An aircraft, comprising a device as specified in claim 5. 7. The process according to claim 5, further comprising actuators for automatically applying to the spoilers of the aircraft said current deflection angle command, determined by said fourth means.
