The invention relates to a travel sensor (10) for electronic components for use in aircraft. Said travel sensor comprises a vibration sensor (11) for converting structure-borne noise to electrical vibration signals. A filter device (20) receives the vibration signals and determines the percentage of engine noise of an aircraft and the overall noise in the vibration signals. A comparator (30) compares the engine noise with the overall noise and generates, based on the result of comparison, a travel state signal representing a defined travel state of the aircraft. Electronic components aboard the aircraft are controlled in such a manner that an emission of disturbing electromagnetic waves is prevented in the "travel" state.

La présente invention concerne un capteur de vol (10) pour des composants électroniques utilisés dans des avions. Ce capteur comprend un capteur de vibrations (11) conçu pour transformer un bruit solidien en signaux de vibration électriques. Un dispositif de filtrage (20) reçoit les signaux de vibration et détermine la proportion de bruits de réacteur d'un avion et le bruit total dans les signaux de vibration. A l'aide d'un comparateur (30) qui compare le bruit de réacteur au bruit total, un signal d'état de vol représentant un état de vol défini de l'avion est produit à partir du résultat de la comparaison. On peut ainsi commander des composants électroniques à bord d'un avion de manière à éviter l'émission d'ondes électromagnétiques parasites lors de l'état </= VOL >/= .
