Abstract: This method consists in: obtaining the positions of the thresholds of the runways of the aerodrome; a runway model being a polygonal modeling of the runways, associating each runway with polygons, a portion common to two secant runways being represented by polygons common to the modelizations of the two secant runways; determining a correction plane of a terrain model located below the thresholds of the runways; defining a contour area around the runway model, based on the runway model and the correction plane; correcting a terrain model so that any point outside the contour area is projected onto the correction plane and any point within the contour area is projected onto the contour area; combining the corrected field model and the runway model to obtain an improved virtual representation.

Abstract: The invention relates to a method for developing a three-dimensional representation of a terrain overflown by an aircraft able to be piloted by a pilot via a control station.
The method includes for representation of at least one current terrain element, following steps: determining a first distance between a first terrain element and the aircraft; determining a second distance between a second terrain element and the aircraft; and calculating a resultant display intensity of the current terrain element as a function of a difference between the first distance and the second distance.
