Questions and Answers

What does ground mode relate to concerning sidestick deflection?

  • It requires auto trim to function properly.
  • It causes reduced elevator deflection.
  • It establishes a direct relationship with elevator deflection. (correct)
  • It alters the relationship between sidestick and elevator.

    • What is a characteristic of ground mode regarding auto trim?

  • Auto trim is mandatory for ground mode.
  • Ground mode allows for automatic trimming.
  • There is no auto trim involved in ground mode. (correct)
  • Auto trim can enhance ground mode performance.

    • Which statement is true about the relationship between sidestick deflection and elevator deflection in ground mode?

  • Sidestick deflection alters the flight parameters significantly.
  • They are directly related without auto trim. (correct)
  • They operate independently of each other.
  • There is a complex relationship requiring calibration.

    Study Notes

    Ground Mode Description

    • Ground mode is an active flight mode engaged on the ground.
    • It directly relates sidestick deflection to elevator deflection, eliminating any automatic trim functions.
