Abstract
A landing system for an aircraft and a method of calculating a reference path. The landing system can calculate a reference path for use during a non-precision approach to a runway, the reference path including a course, flight path angle, and anchor point. The anchor point has a longitude, a latitude and an altitude. The landing system is configured to extract from a navigation database a missed approach point corresponding to a first landing threshold point of the runway. The missed approach point has a longitude, a latitude and an altitude. The landing system is configured such that calculation of the reference path includes setting the altitude of the anchor point with use of the altitude of the missed approach point. The system may be used when approaching a runway having a displaced landing threshold point, the location of the point not being stored in the navigation database.
