12.48 EFIS Instrument Displays

12.48.2 Describe the function and operation of a typical EFIS cockpit display system.

An Electronic Flight Instrument System (EFIS) cockpit display system is an electronic display system that provides pilots with flight information. The system displays flight data, such as altitude, airspeed, heading, vertical speed, and other critical parameters. The system also displays navigation data, such as GPS position, route, and approach information. The EFIS system uses sensors and avionics to collect and process this data and display it on the cockpit displays. The displays are typically large, high-resolution screens that are customizable to suit the pilot's preferences. The EFIS system can also display weather data, traffic information, and other important information to enhance situational awareness. The system is designed to provide pilots with accurate, reliable, and easy-to-read information to facilitate safe and efficient flight operations.

12.48.4 Describe the function of the:

(a) air data computer;

The Air Data Computer (ADC) is an avionics device that collects and processes information from the aircraft's pitot-static system. The ADC measures air pressure, temperature, and other variables to calculate critical flight data, such as airspeed, altitude, vertical speed, and outside air temperature. The ADC also provides this data to other avionics systems, such as the autopilot, flight management system, and cockpit displays. The ADC is designed to provide accurate and reliable information to support safe and efficient flight operations.
