IMPROVED ROBUSTNESS AND AVAILABILITY OF AIRCRAFT ACCELERATION EVALUATION

A system for determining a deceleration rate of an aircraft, in various embodiments, includes at least one component capable of transmitting a first deceleration rate. The system also includes a brake control unit coupled to the at least one component and having a brake controller that is configured to receive the first deceleration rate from the at least one component and to determine a likely accurate deceleration rate based on the first deceleration rate, a second deceleration rate and a hierarchy of sources of deceleration rates.
