1. A method of operating an aircraft, the aircraft having:
a) a landing gear drive system for providing driving torque during taxiing,
b) a landing gear brake system for providing braking torque during taxiing, and
c) a brake command device with a plurality of different command levels over a brake command range,
the method comprising the steps of:
i) during a non-braking time period;
taxiing the aircraft by using driving torque provided by the landing gear drive system, and
not providing a braking torque from the landing gear brake system,
ii) during a braking time period;
providing the brake command device at one or more command levels within a sub-range of the brake command range, and
controlling the landing gear drive system, in response to the level of the brake command device, to reduce the driving torque provided from that in step i) to a lower yet still positive driving torque.
