An aircraft (1) comprising a wing (5) the wing having a fixed wing (7) with a wing tip device (9) moveably mounted about a hinge (11) at the tip thereof. The wing tip device (9) is operable between a flight configuration, and a load alleviating configuration for load alleviation during flight. The aircraft (1) comprises a restraining assembly (17) operable between a restraining mode in which the wing tip device is held in the flight configuration using a restraining force such as by a brake (19), and a releasing mode in which the restraining force on the wing tip device is released, such that the wing tip device (9) may adopt the load alleviating configuration.

    L'invention concerne un aéronef (1) comprenant une aile (5), l'aile ayant une aile fixe (7) munie d'un dispositif de pointe d'aile (9) monté mobile autour d'une charnière (11) au niveau de sa pointe. Le dispositif de pointe d'aile (9) est actionnable entre une configuration de vol et une configuration de réduction de charge pour une réduction de charge pendant le vol. L'aéronef (1) comprend un ensemble de limitation (17) actionnable entre un mode de retenue, dans lequel le dispositif de pointe d'aile est maintenu dans la configuration de vol à l'aide d'une force de retenue par exemple au moyen d'un frein (19), et un mode de libération, dans lequel la force de retenue sur le dispositif de pointe d'aile est libérée, de telle sorte que le dispositif de pointe d'aile (9) peut adopter la configuration de réduction de charge.
