The invention relates to a method and device to assist in navigation in an airport sector. The inventive method and device make it possible to automatically calculate the points of intersection between the path of the flight plan and the zones having speed limitations all around an airport and calculate a speed profile conforming to these limitations. The inventive method and device also make it possible to use an automatic guidance automatically defining flight instructions corresponding to the calculated speed profile. Furthermore, the invention calculates predictions concerning the flight parameters.

1. A method of assisting in navigation in an airport sector including an airport, said sector comprising zones having predefined contours, said method automatically calculating a speed profile observing speed limitations, and comprising the following steps: calculating a lateral path of a flight plan,calculating points of intersection between said path and the contours of said zones by a calculating device belonging to a flight management system or a mission preparation device, said zones being nested within each other so that each of said zones entirely contains the zones of a smaller size, said zones including said airport and being associated with the speed limitations, each zone having a speed limitation lower than the speed limitations of the zones in which it is included,calculating zone change points from said points of intersection by a calculating device belonging to the flight management system or the mission preparation device, andcalculating speed change points from said zone change points by a calculating device belonging to the flight management system or the mission preparation device. 2. The method as claimed in claim 1, wherein said airport is an origin airport of the aircraft and said aircraft is in a climbing phase, a zone change point representing the transition from a first zone to a second zone including said first zone and being the point of intersection between, on the one hand, the path and, on the other hand, the contour of said first zone, the most downstream on said path, corresponding to a definitive exit from said first zone. 3. The method as claimed in claim 2, wherein the speed change points are acceleration start points and are placed at the zone change points. 4. The method as claimed in claim 1, wherein said airport is a destination airport of the aircraft and said aircraft is in descent phase, one of zone change points, representing the transition from a first zone to a second zone included in said first zone, being the point of intersection between, on the one hand, the path and, on the other hand, the contour of said second zone, the most upstream on said path, corresponding to a first entry into said second zone. 5. The method as claimed in claim 4, wherein the speed change points are deceleration start points and are placed on the path upstream of the zone change points so as to form a deceleration segment. 6. The method as claimed in claim 1, further comprising calculating flight parameters notably including speed, trim and thrust. 7. The method as claimed in claim 1, further comprising calculating and displaying predictions of parameters associated with a flight profile including fuel consumption, flight time and predicted speed at each characteristic point of the flight plan. 8. The method as claimed in claim 1, wherein a speed limitation associated with a zone is a value defined by default. 9. The method as claimed in claim 1, wherein a speed limitation associated with a zone is entered manually by the pilot. 10. The method as claimed in claim 1, wherein the speed limitations associated with the zones are dependent on the performance characteristics of the aircraft. 11. The method as claimed in claim 1, further comprising an automatic guidance step defining a flight profile conforming to the calculated flight parameters. 12. The method as claimed in claim 1 is used in flight. 13. The method as claimed in claim 1 is used on the ground for mission preparation. 14. A device to assist in navigation in an airport sector implementing the method as claimed in claim 1, said device comprising: a calculating device configured to automatically calculate a speed profile conforming to said speed limitations and notably including the calculation of speed change points,a calculating device configured to calculate flight parameters including speed, trim and thrust, anda prediction module configured to calculate predictions of parameters associated with the flight profile including fuel consumption and flight time. 15. The device as claimed in claim 14, further comprising a selecting device configured to select a type of speed limitation: dependent on a limitation zone or dependent on an altitude. 16. The device as claimed in claim 14, further comprising a device configured to input and display a speed limitation. 17. The device as claimed in claim 14, further comprising a display device configured to display speed limitation zones. 18. The device as claimed in claim 14, further comprising a guidance device which belongs to a flight management system FMS of an aircraft. 19. The device as claimed in claim 14 belongs to equipment to assist in mission preparation. 20. The device as claimed in claim 19, further comprising a transmitting device configured to transmit to a flight management system FMS.
