Abstract
A system and procedures for controlling a brake status indicator for an aircraft having an electric brake system are disclosed. Electric activation and deactivation of the brake status indicator mimics that of legacy hydraulic brake systems. The control methodology obtains brake force data that indicates actual clamping force of the electric brake actuators, parking brake lever status data that indicates whether the parking brake lever is raised or lowered, and parking brake activation data that indicates whether the parking brake mechanisms are active or inactive. The individual indicator elements of the brake status indicator are independently and concurrently controlled using multiple processing modules/channels of the electric brake system.
