The Military & Aerospace Electronics take:
21 June 2019 -- The Collins auxiliary power engine control unit is a full-authority, advanced electronic controller that controls, monitors, and diagnoses all phases of auxiliary power and engine start system operation.
The controller also transmits fault and maintenance information to the aircraft systems through redundant communication buses. Collins Aerospace’s engine start system includes a starter control valve and air turbine starter that converts pneumatic power, supplied by the APU and controlled by the starter control valve, into mechanical shaft horsepower to start the engine.
The main electric power generation system for the T-X trainer jet will feature Collins Aerospace’s integrated drive generator and digital controls technology to deliver highly reliable constant frequency power.
