Digital Systems Validation Handbook. Volume 2. Chapter 19. Pilot - Vehicle Interface
Abstract
The cockpits of the early transport aircraft were quite different from those produced today. Older cockpits contained numerous steam gauge style indicators. As technology advanced, these older electromechanical indicators were gradually replaced by newer, more reliable digital systems. Digital flight control and avionic systems are being used increasingly in modern aircraft. This trend yields cockpits of greater complexity and has swelled the amount of information with which the crew must deal. The way the pilot controls and monitors the state of the aircraft has also been greatly influenced by the increased use of digital systems. Additionally, new methods of aircraft system monitoring and control are being researched and implemented. These systems use new display technology, programmable display formats, voice input and output, and other new input and control devices. Systems and their cockpit interfaces were added as technological advances were made and new requirements generated. The human interface was given little consideration in the layout of the cockpit. Human qualities and failure modes were not taken into account in the cockpit design process. As the number of systems, components, indicators, and switches multiplied, the potential for error also grew.
