The Pervading Digit: Microprocessors and Digital Maintenance Aids

In 1983 the Boeing 757 will be delivered to British Airways with a triple redundant autopilot, a dual flight management system, a thrust control system, an electronic flight instrument and engine indicating system and many other complex electronic control and indicating systems which will be engineered in digital technology. By way of contrast, in 1927 the first commercial aeroplane built by Boeing, the Model 40, went into service with nothing that could be called avionics and with very little even in the way of electrical equipment.
