The Influence of Microcomputer Technology on Propulsion Management System Design

The rapid pace of digital electronic technology over the last decade has made practical engine-mounted electronic fuel controls for commercial transports. The current status of digital fuel control technology is presented along with a projection of future systems.

The computing power of modern processors makes possible the implementation of extremely complex control modes at modest cost. The ease of using two or more machines in parallel and the capability of the digital computer to test the authenticity of input data leads to interesting techniques for enhancing airworthiness, dispatchability, and maintainability.
