Abstract: A lockable electromechanical actuator including: a screw extending along a longitudinal axis; a nut engaged on the screw and provided with means for connection to an element that is to be moved; and a passive locking device for locking the element that is to be moved in the retracted position; the passive locking device including a device for actuating a lock that can selectively adopt a first position in which the lock prevents relative turning between the screw and the nut, which would lead to the element that is to be moved being deployed, and a second position in which the nut is free to turn, the lock passing from one of its first and second positions to the other one of its first and second positions when the element that is to be moved is taken beyond its retracted position.

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: An actuator includes a screw mounted on a body to pivot, a nut connected to an element for moving, and that is engaged on the screw to be moved between an over-retracted first position and a deployed second position on either side of a retracted third position that is spaced apart from the over-retracted position by a distance corresponding to the screw rotating through a first angular sector and an anti-extension device comprising a friction disk having at least one smooth surface and an obstacle both for co-operating with at least one pawl, thereby defining both at least one second angular sector of free rotation for the friction disk and also a position for blocking the friction disk.

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.

Abstract: A lockable actuator includes: a body; a screw for pivoting relative to the body; a nut engaged on the screw so as to move along the screw between an over-retracted first position and a deployed second position on opposite sides of a retracted third position; a sleeve constrained to rotate with the screw and slidably mounted thereon in order to be moved by the nut; and an obstacle secured to the sleeve and a pawl capable of passing collectively between an active state and an inactive state, the pawl and the obstacle being arranged in such a manner that the pawl in its active state can co-operate with the obstacle only after the nut has been moved through a predetermined distance from its third position towards its second position.
