Abstract: A method of managing the braking of an aircraft, the aircraft having a plurality of wheels R1, . . . , R12, each fitted with a brake F1, . . . , F12 adapted to generate a braking force in response to brake pedals 5 being depressed. The management method comprising the steps of (1) distributing the wheels fitted with respective brakes in at least two distinct groups G1, G2, G3, G′1, G′2, G′3; (2) allocating respective braking relationships to each of the groups of wheels for determining how braking force varies as a function of the depression of the brake pedals; and (3) acting at predetermined intervals to permutate the allocation of the relationships to the groups in application of a predefined permutation relationship. The method also includes a step of modifying the permutation relationship in response to the occurrence of a predetermined event.

Abstract: Measurement equipment for measuring the inflation pressure of a tire of a vehicle wheel 1. The equipment comprises a body 16 defining an internal volume, a communication orifice 19 for putting the inside volume of the body 16 into communication with an inflation chamber situated between a rim 2 and a tire of the wheel and containing an inflation gas and an indicator member 25 slidably mounted in the body 16 so as to define a gastight separation between a first chamber 26 containing a given quantity of a reference gas and a second chamber 27 into which the communication orifice 19 leads. As a result, the indicator member 25 is subjected to opposing pressures that exist in each of the chambers. A position-identification device 30 is operative to identify the position of the indicator member in the body.
