Abstract
A system for configuring a full authority digital engine controller (FADEC) for use with an engine and an airframe combination. The system includes the FADEC and a data entry plug. The FADEC includes an electronic engine controller (EEC) attached to the engine, an airframe data concentrator (ADC) attached to the airframe, and a digital bus electrically connecting the ADC to the EEC. The ADC includes a data storage device and a data entry plug socket. The data entry plug includes electrical components configured for the engine and the airframe combination. The data entry plug is inserted into the data entry plug socket to direct the ADC to recall configuration data from the data storage device for the engine and the airframe combination and send the configuration data over the digital bus to the EEC.
