With a device for error detection of adjustable flaps (1,2) on aircraft wings, it is proposed that each flap (1,2) is provided with a tube (7) as a transmission element arranged in the wing span. The tube (7) is connected fixedly at one end with the flap (1,2) and is rotatably held. On the free end of the tube, a measuring arm (11) is fixedly arranged on the tube (7) and a sensor (12) fixed to the flap structure is arranged. When an error occurs, the flap (1,2) twists, whereby a distance change between the sensor (12) and measuring arm (11) occurs. The signals of the sensor (12) are transmitted for error localization of each flap to an evaluation device, which switches off the drive via a control device with occurring errors.

Selon l'invention, avec un dispositif permettant de détecter des erreurs de volets réglables (1, 2) sur des ailes d'aéronef, l'invention recommande que chaque volet soit doté d'un tube (7) servant d'élément de transmission disposé dans l'envergure de l'aile. Le tube (7) est relié de manière fixe à une extrémité avec le volet (1, 2), et il est maintenu de manière à pouvoir tourner. Sur l'extrémité libre du tube, un bras de mesure (11) est disposé de manière fixe sur le tube (7) et un capteur (12) est disposé, fixé à la structure de volet. Lorsqu'il se produit une erreur, le volet (1, 2) se tord, ce qui modifie ainsi la distance entre le capteur (12) et le bras de mesure (11). Les signaux du capteur (12) sont transmis, en vue de localiser les erreurs de chaque volet, à un dispositif d'évaluation qui met hors service le dispositif d'entraînement par l'intermédiaire d'un dispositif de commande, lorsque des erreurs se produisent.
