Abstract: Said method for determining aircraft landing runway conditions comprises the steps of: acquiring a set of data groups of different types (D1, D2) for evaluating and monitoring runway degradation conditions; deriving weighting coefficients (Ki) from each data group; filtering the data; determining, for each data group, a partial runway condition; modifying the weighting coefficients of each data group; and combining the partial runway conditions to derive a runway condition coefficient (RWYCC) associated with a confidence index (C1) derived from the modified weighting coefficients.

Abstract: A system for real-time control of the trajectory of an aircraft on a runway, includes at least one steering system configured to steer the aircraft on the ground, each steering system being associated with at least one use parameter; a computer configured for determining, from aircraft data and external data including runway condition data and ground meteorological data, each steering system intended to steer the aircraft according to a predetermined trajectory and each corresponding use parameter; and a control system configured to control each steering system determined according to each corresponding determined use parameter.

Abstract: This system (36) for controlling an aircraft thrust reversal means comprises a reverse idle control means (38), a first detection means (31) configured to detect, when the reverse idle control is active, a condition for activation of the thrust reversal means, and an actuation means (52) configured to activate the thrust reversal means when the first detection means (31) detects a condition for activation of the thrust reversal means. It further comprises a second detection means (42, 44, 46, 48, 49) configured to detect a condition for activation of the reverse idle control, the control means (38) being configured to activate the reverse idle control when the second detection means (42, 44, 46, 48, 49) detects a condition for activating the reverse idle control.
