Abstract :
The features of the SAIT 1184 computer, which is the heart of the Comprehensive Engine Diagnostic System (CED), are described. Operation of the CED System 1184 computer is menu-driven to prompt the user from one function to another. A single-point connection on the engine permits retrieval and display of stored Engine Diagnostic Unit data and fault codes. A second single point connection near the Digital Electronic Engine Control (DEEC) is used to retrieve DEEC fault data and display real-time digital data. The CED computer can operate on a 24 V battery or can use 115 V AC 50-400 Hz (with a converter) from a flight-line power cart or other available sources to power itself and the Engine Diagnostic Unit. The CED computer will be used on the flight line as well as in test cell environments. The following features are discussed in detail: power consumption and processing power, application memory, and expansion boards
