Abstract

A method for assisting in the navigation of an aircraft comprises steps of calculating and displaying a linear deviation on a first linear section and an angular deviation on a second angular section. The method comprises a calculation step for converting an angular deviation into an equivalent linear deviation, and, conversely, converting a linear deviation into an equivalent angular deviation. The method comprises a step of graphic representation, called unified monitoring, intended for the crew, of a deviation of the aircraft, on a lateral deviation axis and a vertical deviation axis; each of the deviations, lateral and vertical, being able to be represented on a linear scale, an angular scale or a mixed scale.

First claim

The invention claimed is:

1. A method for assisting in the navigation of an aircraft navigation, the method comprising:
calculating and displaying a linear deviation, expressed by a lateral component and a vertical component, for an aircraft in an approach phase towards an arrival airport on a first section, called a linear section, the linear deviation representing a distance separating an estimated position of the aircraft and a desired position on a target trajectory;
calcula…
