Abstract
An electric brake system for an aircraft as described herein electrically actuates brake mechanisms in a seamless manner when a power interrupt condition is experienced. While operating in an autobraking mode and in response to a power interrupt condition, the electric brake system preserves the last brake actuation command generated by the autobrake function. After normal operating power is reestablished, the last brake actuation command is retrieved and processed by the electric brake system. While operating in a pedal braking mode and in response to a power interrupt condition, the electric brake system discards the last brake actuation command generated from brake pedal interaction. After normal operating power is reestablished, the brake pedal data is refreshed to generate a new brake actuation command. These procedures reduce lurching and unexpected brake actuation levels following a power interrupt in the electric brake system.
