METHOD AND DEVICE FOR DETERMINING THE WIDTH OF A SAFETY CORRIDOR FOR AN AIRCRAFT AND METHOD AND SYSTEM FOR SECURING THE AUTOMATIC LOW-ALTITUDE FLIGHT OF AN AIRCRAFT

摘要

The invention relates to a method and device for determining the width of a safety corridor for an aircraft and to a method and system for securing the automatic low-altitude flight of an aircraft. The inventive device (1) comprises: means (3) which can be used by an operator in order to enter a plurality of errors which each have an impact on the automatic low-altitude flight of the aircraft; means (4) for determining an excursion probability of a safety corridor that is not to be crossed; and means (5) for determining the width of said safety corridor from the aforementioned errors and excursion probability, taking account of at least one mathematical expression linking at least the errors, the excursion probability and the width.
