Abstract: Disclosed is a method for updating a list of radio stations that can be received by a receiver system including at least two radio receivers, the method including: ?determining a list of radio stations that can be received at a given instant, ?measuring the quality of a current radio signal, corresponding to a frequency selected and listened to, ?determining the ageing of the list of receivable radio stations, ?comparing the quality with a configurable threshold that can be upgraded at least as a function of the ageing of the list, ?if the quality exceeds the configurable threshold, deactivating the phase diversity filtering function and evaluating the change in the quality of the received signals and, ?as a function of the evaluation:—automatically updating, or—keeping unchanged the list of receivable radio stations.

Abstract: A pitch-oscillation limitation system, applied to an aircraft having main landing gear located toward the center of the aircraft and forward landing gear located under the nose of the aircraft, wherein the system includes means for automatically applying, in the event of sudden braking, time-deferred braking between the wheels of the landing gear under the wings and the wheels of the landing gear under the fuselage, so as to reduce the amplitude of the aircraft's pitching motion.
