A method of managing a steering command for a steerable portionof nose landing gearof an aircraft. The method implements servo-control to servo-control of a steering actuatorto an angle position setpoint &#x3b8;set for the steerable portion. The servo-control includes calculating an error &#x3b5; by subtracting a reference angle &#x3b8;est from the angle position setpoint &#x3b8;set. The reference angle &#x3b8;est is an angle determined by calculation as a function of a longitudinal speed Vlong and a yaw rate &#x3c4; of the aircraft

A method of managing the braking of an aircrafthaving at least one controllable brakefor braking the aircraftwhen the aircraftis on the ground and as a function of a braking setpoint C. The method includes correcting the braking setpoint as a function of the pitch angle &#x3b8; of the aircraftduring braking.

Method of managing the braking of an aircraft to limit its pitch

A method of managing the steering of aircraft undercarriage wheels carried by a steerable bottom portion of the undercarriage, the bottom portion being associated with steering control including a steering member suitable for steering the bottom portion of the undercarriage in response to a steering order. The method comprises the steps of (1) monitoring the pressures of the tires carried by the wheels, and in response to detecting at least one of the following events: (1A) the pressure of one of the tires is less than a first predetermined threshold, and ( 1B) the difference between the pressures of two of the tires is greater than a second determined threshold; (2) activating the steering control, if the steering control is not activated; and (3) implementing a steering control relationship that is modified compared with a nominal control relationship used when the tires are properly inflated.
