1. A method for facilitating performing an altitude change maneuver within reduced spacings of an airplane (AC) flying at a current altitude level (Nc), according to a given course, for capturing a target altitude level (Na), said airplane (AC) being provided with receiving means (2) for information relating to aircrafts flying in an air environment in the vicinity of said airplane (AC), comprising: defining, via a processor, a target altitude level to be captured (Na), based on a received target altitude level selection;determining, via a processor, a control volume (V) around said airplane (AC), a first dimension (h) of which is a function of the altitude difference between said current level (Nc) and said target level (Na), a second dimension (L) of which depends on a first distance threshold (s1) and a third dimension (I) of which depends on a second distance threshold (s2),wherein the first distance threshold is a predefined horizontal separation between the airplane and at least one other aircraft flying in the air environment,wherein the second distance threshold is a predefined side separation between the airplane and at least one other aircraft flying in the air environment, andwherein the second distance threshold is measured in a direction perpendicular to the first distance threshold;locating, via a processor, the presence of at least one aircraft (ACd1, ACd2, ACref) inside said control volume (V);checking, via a processor, whether the following activation conditions are met: the distance separating said airplane (AC) from said located aircraft is strictly lower than said first distance threshold (s1) and is at least equal to a third distance threshold (dITP),wherein the third distance threshold is a predetermined minimum separation distance between the airplane and at least one other aircraft flying in the air environment; andthe angle formed between the course of said airplane (AC) and the course of said located aircraft is at the most equal to a predefined angle threshold; andwhen said located aircraft (ACref) meets said activation conditions, from information from said located aircraft (ACref) received by said reception means (2), determining, via a processor, a performing time range, during which said altitude change maneuver is able to be performed,wherein a performing authorization request is generated automatically, via a processor, but held until a pilots' order is received to transmit the request to air traffic control (5). 2. A method according to claim 1, wherein said time range is determined only when at least one and at the most two aircrafts (ACref) are located in said control volume (V) and they each meet said activation conditions. 3. A method according to claim 1, wherein said performing time range is determined from the relative velocity of said airplane (AC) with respect to said located aircraft (ACref) meeting said activation conditions and the relative position of said airplane (AC) with respect to said aircraft (ACref). 4. A method according to claim 1, wherein said authorization request comprises relative position information of said airplane (AC) with respect to said located aircraft (ACref) meeting said activation conditions, as well as information relating to the desired altitude change maneuver within reduced spacings. 5. A method according to claim 1, wherein said control volume (V) has the form of a rectangular parallelepiped with the height thereof (h) corresponding to said first dimension. 6. A device for facilitating performing an altitude change maneuver within reduced spacings of an airplane (AC) flying at a current altitude level (Nc), according to a given course, for capturing a target altitude level (Na), said airplane (AC) being provided with receiving means (2) for information relating to aircrafts flying in an air environment in the vicinity of said airplane (AC), comprising: means (4) for defining a target altitude level (Na) to be captured, based on a received target altitude level selection;means (7) for determining a control volume (V) around said airplane (AC), a first dimension (h) of which is a function of the altitude difference between said current level (Nc) and said target level (Na), a second dimension (L) of which depends on a first distance threshold (s1) and a third dimension (I) of which depends on a second distance threshold (s2),wherein the first distance threshold is a predefined horizontal separation between the airplane and at least one other aircraft flying in the air environment,wherein the second distance threshold is a predefined side separation between the airplane and at least one other aircraft flying in the air environment, andwherein the second distance threshold is measured in a direction perpendicular to the first distance threshold;means (8) for locating the presence of at least one aircraft (ACd1, ACd2, ACref) inside said control volume (V);means (9) for checking that the following activation conditions are met: the distance separating said airplane (AC) from said located aircraft is strictly lower than said distance threshold and is at least equal to a third distance threshold (dITP),wherein the third distance threshold is a predetermined minimum separation distance between the airplane and at least one other aircraft flying in the air environment; andthe angle formed between the course of said airplane (AC) and the course of said located aircraft is at the most equal to a predefined angle threshold; andmeans (10) for determining, from information from said located aircraft (ACref) received by said receiving means (2), a performing time range during which said altitude change maneuver is able to be performed, said means (10) being activated when said located aircraft (ACref) meets said activation conditions,wherein a performing authorization request is generated automatically, via a processor, but held until a pilots' order is received to transmit the request to air traffic control (5). 7. A device according to claim 6, wherein it comprises means (11) for automatically generating a performing authorization request to be transmitted, on pilots' order, to the air traffic control (5). 8. An airplane, comprising a device (1), according to claim 6.
