The function of a CRT in an EFIS is to

  1. Generate power for the system

  2. Process input signals

  3. Display alphanumeric data and representations of aircraft instruments

  4. Control the aircraft's autopilot system

The correct answer is: Display alphanumeric data and representations of aircraft instruments

The function of a Cathode Ray Tube (CRT) in an Electronic Flight Instrument System (EFIS) is to display alphanumeric data and representations of aircraft instruments. This means that it is responsible for visually displaying important information to the pilot such as airspeed, altitude, and heading. Option A is incorrect because power for the system is typically generated by the aircraft's battery or generator, not the CRT. Option B is incorrect because processing input signals is typically done by the central computer, not the CRT. Option D is incorrect because the autopilot system is typically controlled by a separate panel or controller, not the CRT. Overall, the CRT plays a vital role in providing important information and data to the pilot for safe and efficient flight.
