Abstract
A system for assisting in the landing of an aircraft including a processing unit configured to: during a first phase of a landing runway approach procedure, when the aircraft flies above a predetermined height with respect to a landing runway threshold, determine a bias of position and speed information from an inertia unit of the aircraft, as a function of the merged position and speed information determined as a function of information from a receiver of ILS guidance signals and of information from a signal receiver of a satellite navigation system, then, during a second phase of the approach procedure, when the aircraft flies below the predetermined height, determine so-called adjusted aircraft position and speed information by applying, to information from the inertial unit, a correction corresponding to the bias determined during the first phase of the approach procedure.
