What AFCS means

Autopilot has failed. p. 240

Common causes

  • Autopilot has failed. p. 240
  • Autopilot normal disconnect. p. 240
  • Autopilot abnormal disconnect. p. 240
  • Autopilot has failed. The autopilot is inoperative. FD modes may still be available. p. 240
  • Autopilot preflight test is in progress. p. 240
  • Pitch Trim Fail – Manual Electric Pitch Trim is inoperative. p. 240
  • WARNING: Do not assume ESP will provide stability protection in all circumstances. There are in-flight situations that can exceed the capabilities of ESP technology. p. 240
  • WARNING: A GPS navigator that can provide AGL height data is required for low-airspeed protection. p. 240
  • WARNING: The autopilot (or ESP) will disengage if the roll attitude exceeds 75° or the pitch attitude exceeds 50°. p. 240
  • When selected, ESP engages automatically when the aircraft approaches or exceeds one or more predetermined airspeed or attitude limitations. Stability protection for each flight axis is provided by the autopilot servos, which apply force to the appropriate control surface(s) to discourage pilot control inputs that would cause the aircraft to exceed the normal or "protected" flight envelope. p. 240
  • If enabled, this feature will automatically arm when the aircraft is above 500 feet AGL and the autopilot is not engaged, and disarm when below 200 feet AGL. (If AGL height data is unavailable, ESP can be armed on the ground, but low-airspeed protection will not be available.) p. 240
  • When ESP has been engaged for more than 10 seconds (cumulative; not necessarily consecutive seconds) of a 20-second interval, the autopilot can be configured to engage with the flight director in Level Mode, bringing the aircraft into level flight. An aural 'Engaging Autopilot' alert is played and the flight director mode announcement will indicate 'LVL' for vertical and lateral modes. p. 240
  • Level mode as activated by ESP is limited by altitude. ESP will not be able to activate Level mode until the aircraft climbs above 2000 feet AGL. ESP will be locked out of automatically activating Level mode after the aircraft descends below 1500 feet AGL as well. p. 240
  • Also note that Level mode as activated by ESP is different than manually selected Level mode. Manually selected Level mode is not limited by altitude at all. p. 240
  • ESP is enabled or disabled from the ADI Page Menu. p. 240

What to do

  1. Autopilot and trim are inoperative and flight director is not available. p. 240
