Abstract:
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, and calculating speed change points from said zone change points by a calculating device belonging to the flight management system or the mission preparation device.
