A method to control braking of an aircraft on a landing runway including: selecting a dummy runway state corresponding to a level of adhesion of wheels of the aircraft to a runway which is lower, over an entire speed range of the aircraft while braking on a runway, than an adhesion level of the wheels of the aircraft to the landing runway; calculating a set point of a deceleration value for the aircraft on the landing runway based on the landing runway for the selected dummy runway state, wherein the calculated set point corresponds to maximum braking value of the aircraft, and controlling the braking of the aircraft using the set point.
