<p>The invention relates to a method for determining the distance from an aircraft to an offset runway (15) during landing with an offset approach, the offset runway (15) being located at a distance D from a main runway (11) provided with at least one elevation marker (12), characterised in that said method includes at least the following steps: determining the current height h of the aircraft (1), height which is determined in relation to a point T1 of the offset runway (15), height which is measured by a radio altimeter installed on the aircraft; determining the angle of elevation f of the MLS mode using the information from the elevation marker (12) supplied by an elevation marker (12) installed on said main runway (11); determining the value of the distance p from the airplane to the azimuth marker (10) using the following formula (I); using said distance p to obtain an aircraft location point in a frame of reference of the offset runway (15).</p> |
