Questions and Answers

What is the primary function of the flux gate system in an aircraft?

  • To provide a visual display of the aircraft's attitude
  • To generate a signal for the radio communication equipment
  • To sense the aircraft's altitude
  • To continuously sense the earth's magnetic field (correct)

What is the benefit of slaved gyros in an aircraft?

  • They increase the pilot's available scan time
  • They enable the aircraft to fly at higher speeds
  • They provide a more accurate altimeter reading
  • They reduce pilot workload by eliminating the need for manual realignment (correct)

What is the primary function of the heading indicator unit?

  • To process the gyro unit until it is aligned with the transmitter signal (correct)
  • To generate a signal for the radio navigation equipment
  • To display the aircraft's rate of turn
  • To provide a visual display of the aircraft's altitude
