Claim 0:
1. An aircraft brake control system for controlling antiskid braking of a wheel of an aircraft, the system comprising a control assembly having:
i) an input of an indication of a wheel speed of the wheel,
ii) an input of an indication of a brake level,
iii) an input of an indication of a brake energy supply configuration,
iv) an antiskid brake calculator, for calculating an antiskid brake command based on the wheel speed and brake level,
v) a mode controller which sets the mode of operation of the antiskid brake calculator, the mode controller configured to set:
a first mode, when the input of the indication of a brake energy supply configuration indicates a first brake energy supply being used, in which the antiskid brake calculator applies a first restriction level on a rise rate of the antiskid brake command, and
a second mode, when the input of the indication of a brake energy supply configuration indicates a second brake energy supply being used, in which the antiskid brake calculator applies a second restriction level on a rise rate of the antiskid brake command, the second restriction level being lower than the first restriction level, and

vi) an output for indicating the antiskid brake command to be sent to a brake valve:
wherein the antiskid calculator comprises an antiskid computator, for computating an initial antiskid command, and a restrictor device for receiving the initial antiskid command and then applying a rise rate restriction.
