Abstract
An aircraft system for an aircraft having a controller configured to determine, based on a criterion indicative of an aircraft condition or a runway condition, a maximum braking level able to be applied to a brake of the aircraft in an emergency braking mode, wherein the maximum braking level is determined to be a first maximum braking level when a value of the criterion is above a pre-determined threshold and a second maximum braking level when a value of the criterion is no greater than the pre-determined threshold.

An aircraft system for an aircraft, the aircraft system comprising a controller configured to determine, based on a criterion indicative of an aircraft condition or a runway condition, a maximum braking level that the aircraft system is able to apply to a brake of the aircraft in an emergency braking mode, wherein the maximum braking level is determined to be a first maximum braking level when a value of the criterion is greater than a pre-determined threshold, and a second maximum braking level different to the first maximum braking level when a value of the criterion is no greater than the pre-determined threshold,
- wherein the controller is configured to determine the first and second maximum braking levels while the aircraft is in-flight and before the controller determines the maximum braking level, and
- the controller is configured to limit a level of braking that can be applied to the brake by the aircraft system to the maximum braking level in the emergency braking mode.
An aircraft braking system comprising:
- a brake,
- a braking power source, and
