Method and system for aiding the piloting of an aircraft, during a maneuver bringing about an increase in the attitude of the aircraft

A method of aiding the piloting of an aircraft during a maneuver bringing about an increase in the attitude of the aircraft, according to which method the following steps are carried out automatically and repeatedly:

• a) a first value of attitude of the aircraft is taken into account;
• b) the current attitude of the aircraft is determined;
• c) an attitude deviation is determined by subtracting said first value of attitude from said current attitude;
• and
• d) at least one horizon line is presented on a display screen of a head-up display device, superimposed with the environment seen in front of the aircraft, wherein:
• in step d), a first section of indication which indicates said attitude deviation is moreover presented on said display screen, and
• said first value of attitude corresponds to the minimum value between, on the one hand, an optimal value of attitude at the end of the maneuver and, on the other hand, a value of attitude of protection against a rear collision.

A system for aiding piloting for an aircraft, said system comprising:

• a set of information sources, comprising at least one information source which determines a current attitude of the aircraft;
• a first section that transmits a first value of attitude;
• a second section that determines an attitude deviation, by subtracting said first value of attitude from said current attitude;
• a calculation unit which is connected to said set of information sources;
• and
• a head-up display device, which is connected to said calculation unit and which is able to present, on a display screen, superimposed with the environment seen in front of the aircraft, at least one horizon line, wherein:
• said display device moreover presents on said display screen, superimposed with the environment seen in front of the aircraft, at least one first section of indication indicating said attitude deviation determined by said second section, and
• said first section is formed so as to transmit, as the first value of attitude, the minimum value between, on the one hand, an optimal value of attitude at the end of the maneuver and, on the other hand, a value of attitude of protection against a rear collision.
