Advances in digital display and electronic components have been introduced into the flight decks of aircraft. EFIS is an electronic flight instrument system of graphically presented displays with underlying sensors, electronic circuitry, and software. It enhances the efficiency and ease of flight management. Electronic flight instrument systems packages are less likely to fail than their analogue counterparts. It’s no longer necessary for aircraft designers to create cluttered panel layouts in order to accommodate all the necessary flight instruments. An EFIS normally consists of a primary flight display (PFD), a multi-function display (MFD), and an Engine Indicating and Crew Alerting System (EICAS) display. It contains high-resolution cathode ray tubes which display the flight information, navigational data, and performance data, including engine and aircraft operating parameters, stall warning, data acquisition for the flight data recorder, and for maintenance and diagnostics.
