The guiding mode transition aiding device includes a target heading determining device and a mode transition triggering system. The target heading determining device is configured to determine a target heading which represents the heading value reached by the aircraft at the end of a procedure of folding the wings of the aircraft flat from a current operating state. The mode transition triggering system receives the target heading and compares the target heading to a desired heading to be reached by the airplane to assist with triggering a transition between a rolling angle holding mode, in which the aircraft flies with a constant rolling angle, to a heading holding mode, in which the aircraft flies with a constant heading. This device and associated methods may be used during in flight refueling operations.

1. A method for guiding an airplane to manage a transition from a rolling angle holding mode, wherein the airplane flies with a constant rolling angle, to a heading holding mode, wherein the airplane flies according to a constant heading with wings of the airplane being folded flat, the method comprising: determining, by a target heading determining device including a calculation unit, a target heading representing a heading value that will be reached by the airplane at the end of a procedure of flat folding the wings of the airplane, initiated at the current instant, from a current operating state of the airplane while automatically performing the following operations: calculating, by a heading deviation calculator of the calculation unit, a heading deviation, equal to a heading change required for folding the wings of the airplane flat, from the current operating state of the airplane; andsumming, by an adding calculator of the calculation unit, the heading deviation and a current heading of the airplane to determine the target heading; andtransmitting the target heading to a mode transition triggering system including at least one display screen in a cockpit of the airplane, such that the target heading is compared to a desired heading to be reached by the airplane to aid in triggering the transition from the rolling angle holding mode to the heading holding mode when the target heading matches the desired heading to be reached. 2. The method according to claim 1, wherein calculating the heading deviation further comprises: retrieving a predetermined conversion function, allowing to convert a heading deviation into a corresponding rolling control;inverting the conversion function and applying the inverted conversion function to a current rolling angle of the airplane so as to obtain the heading deviation. 3. The method according to claim 2, wherein calculating the heading deviation further comprises: determining the current rolling angle of the airplane;comparing the current rolling angle to a predetermined value, and:if the current rolling angle is lower than or equal to the predetermined value, the heading deviation is determined by applying the inverted conversion function;if the current rolling angle is higher than the predetermined value, the heading deviation is determined by an alternative process based on the current rolling angle and at least one predetermined conversion table. 4. The method according to claim 3, wherein: when the current rolling angle is lower than or equal to the predetermined value, a rolling authority of the airplane is limited to the constant rolling angle; andwhen the current rolling angle is higher than the predetermined value, the rolling authority of the airplane is limited to the predetermined value. 5. The method according to claim 1, wherein transmitting the target heading further comprises: showing the target heading on display screens in the cockpit, such that a manual triggering device of the mode transition triggering system may be used by a pilot of the airplane to manually control triggering of the heading holding mode based on information shown at the display screens. 6. The method according to claim 1, wherein transmitting the target heading further comprises: automatically comparing the target heading to a setpoint value input to the mode transition triggering system; andautomatically triggering, by an automated triggering device included in the mode transition triggering system, the transition to the heading holding mode, when the target heading becomes equal to the setpoint value. 7. The method according to claim 6, further comprising: receiving the setpoint value at the mode transition triggering system when the setpoint value is inputted manually by a pilot of the airplane. 8. The method according to claim 6, further comprising: receiving the setpoint value at the mode transition triggering system when the setpoint value is inputted automatically. 9. The method according to claim 1, further comprising: switching between the rolling angle holding mode and the heading holding mode, successively and alternately, during a flight refueling phase of the airplane (AC) is involved, andrepeating the determining and transmitting steps to aid in transitioning between modes. 10. A guiding mode transition aiding device configured to guide an airplane and aid in managing a transition from a rolling angle holding mode, wherein the airplane flies with a constant rolling angle, to a heading holding mode, wherein the airplane flies according to a constant heading with wings of the airplane being folded flat, the guiding mode transition aiding device comprising: a target heading determining device including a calculation unit that determines a target heading representing a heading value that will be reached by the airplane at the end of a procedure of flat folding of the wings of the airplane, initiated at the current instant, from a current operating state of the airplane, wherein the target heading determining device calculates a heading deviation equal to a heading change required for folding the wings of the airplane flat, from the current operating state of the airplane, and sums the heading deviation and a current heading of the airplane to determine the target heading; anda mode transition triggering system including at least one display screen in a cockpit of the airplane, which receives the target heading transmitted from the target heading determining device and compares the target heading to a desired heading to be reached by the airplane to aid in triggering the transition from the rolling angle holding mode to the heading holding mode when the target heading matches the desired heading to be reached. 11. The guiding mode transition aiding device according to claim 10, wherein the target heading determining device calculates the heading deviation by: retrieving a predetermined conversion function, allowing to convert a heading deviation into a corresponding rolling control;inverting the conversion function and applying the inverted conversion function to a current rolling angle of the airplane so as to obtain the heading deviation;determining the current rolling angle of the airplane;comparing the current rolling angle to a predetermined value, andif the current rolling angle is lower than or equal to the predetermined value, the heading deviation is determined by applying the inverted conversion function;if the current rolling angle is higher than the predetermined value, the heading deviation is determined by an alternative process based on the current rolling angle and at least one predetermined conversion table.
