1. A power plant having at least one engine and control means for controlling the engine, wherein the control means include a memory, the memory containing information enabling the engine to be operated in accordance with at least two distinct utilization envelopes during a maximum number of flying
1. A power plant having at least one engine and control means for controlling the engine, wherein the control means include a memory, the memory containing information enabling the engine to be operated in accordance with at least two distinct utilization envelopes during a maximum number of flying hours, each utilization envelope including at least two distinct utilization ratings each defined by a developed power and a utilization duration for the developed power, the at least two envelopes comprising an envelope that enables takeoff to be optimized from a platform and another envelope that enables takeoff to be optimized from takeoff zones that do not include platforms. 2. The power plant according to claim 1, including pilot-operable selector means, the selector means being connected to the control means to enable a pilot to select a utilization envelope in accordance with which of the engines is to operate. 3. The power plant according to claim 2, wherein the power plant comprises two engines of an aircraft, the selector means include at least two positions each associated with a respective utilization envelope, the two positions being for selection from a list including: a first position for taking off from a platform situated at a first height with a maximum weight that can be transported by the aircraft and requiring the engines to operate in accordance with a first utilization envelope;a second position for taking off from a platform situated at a second height, with a maximum weight transportable by the aircraft and requiring the engines to operate in accordance with a second utilization envelope;a third position for taking off from a takeoff zone having a first obstacle-free area and distinct from a platform, with a maximum weight transportable by the aircraft and requiring the engines to operate in accordance with a third utilization envelope; anda fourth position for taking off from a takeoff zone having a second obstacle-free area and distinct from a platform, with a maximum weight transportable by the aircraft and requiring the engines to operate in accordance with a fourth utilization envelope. 4. The power plant according to claim 1, including safety means for ensuring that an envelope is deliberately selected before beginning a flight. 5. The power plant according to claim 1, wherein the power plant includes display means displaying either the utilization envelopes, or the utilization ratings implemented by the power plant, or the utilization envelopes and the utilization ratings of the utilization envelopes that are being implemented by the power plant. 6. The power plant according to claim 1, wherein the power plant has two engines, each utilization envelope including at least one contingency rating suitable for use when one of the engines breaks down, with a contingency rating of one envelope differing from a contingency rating of another envelope. 7. An aircraft, including the power plant according to claim 1. 8. A method of piloting an aircraft provided with a power plant including at least one engine and control means for controlling the engine, the method comprising: defining a list of utilization envelopes for the engine, the list comprising at least two distinct utilization envelopes, each associated with the same number of maximum flying hours for the engine, each utilization envelope having at least two utilization ratings, each defined for a developed power and for a utilization duration of the developed power;storing the utilization envelopes in the control means; andprior to takeoff, selecting an envelope for use from the list as a function of the mission that is to be performed, wherein the at least two envelopes comprise an envelope enabling takeoff to be optimized from a platform and another envelope enabling takeoff to be optimized from takeoff zones not including platforms. 9. The method according to claim 8, wherein the power plant comprises two engines, and for each utilization envelope at least one contingency rating is defined suitable for use when one of the engines breaks down, a contingency rating of one envelope differing from a contingency rating of another envelope. 10. The method according to claim 8, wherein the power plant comprises two engines and the list includes at least two distinct utilization envelopes suitable for use over the same number of flying hours, the list comprising: a first utilization envelope for taking off from a platform situated at a first height and with a maximum weight transportable by the aircraft;a second utilization envelope for taking off from a platform situated at a second height and with a maximum weight transportable by the aircraft;a third utilization envelope for taking off from a takeoff zone having a first obstacle-free area and distinct from a platform, with a maximum weight transportable by the aircraft; anda fourth utilization envelope for taking off from a takeoff zone having a second obstacle-free area and distinct from a platform, with a maximum weight transported by the aircraft. 11. A power plant having at least one engine and a control for controlling the engine, the control including a memory containing information enabling the engine to be operated in accordance with at least two distinct utilization envelopes during a maximum number of flying hours, with each utilization envelope including at least two distinct utilization ratings each defined by a developed power and a utilization duration for the developed power, the at least two envelopes comprising a first envelope that enables takeoff to be optimized from a platform and a second envelope that enables takeoff to be optimized from takeoff zones that do not include platforms. 12. The power plant according to claim 11, including pilot-operable selector connected to the control to enable a pilot to select one of the utilization envelopes. 13. The power plant according to claim 12, wherein the power plant comprises two engines of an aircraft, the selector includes at least two positions each associated with a respective utilization envelope, the two positions being for selection from a list including: a first position requiring the engines to operate in accordance with a first utilization envelope;a second position requiring the engines to operate in accordance with a second utilization envelope;a third position requiring the engines to operate in accordance with a third utilization envelope; anda fourth position requiring the engines to operate in accordance with a fourth utilization envelope. 14. The power plant according to claim 12, wherein the power plant comprises two engines of an aircraft, the selector includes at least two positions each associated with a respective utilization envelope, the at least two positions being for selection from a list including: a first position for taking off from a platform situated at a first height with a maximum weight that can be transported by the aircraft and requiring the engines to operate in accordance with a first utilization envelope;a second position for taking off from a platform situated at a second height, with a maximum weight transportable by the aircraft and requiring the engines to operate in accordance with a second utilization envelope;a third position for taking off from a takeoff zone having a first obstacle-free area and distinct from a platform, with a maximum weight transportable by the aircraft and requiring the engines to operate in accordance with a third utilization envelope; anda fourth position for taking off from a takeoff zone having a second obstacle-free area and distinct from a platform, with a maximum weight transportable by the aircraft and requiring the engines to operate in accordance with a fourth utilization envelope. 15.
