Abstract
The field of the invention is that of the display in map form of an operating zone of an aircraft on a screen, and more particularly a method of processing topographic data of this operating zone of an aircraft in real time, based on a calculation of radials (R) centred on a reference point (O) defining an angular segment of topographic data. According to the invention, the method includes a subdivision of the operating zone to be mapped into a plurality of angular segment sections, each forming an individual zone (3), and an assignment of a processing priority and a refresh frequency specific to each individual zone defined according to a criterion of operational interest of the element to the aircraft.
