Autopilot gps flight control system8/12/2023 ![]() Notice that the active thrust mode on the flight mode annunciator (FMA) is now A.FLOOR or TOGA LK boxed in an amber color and flashing. During TOGA LK the TOGA thrust is kept until you manually move your thrust levers. When the angle of attack reduces again or when the pilot holds the side-stick forward for about one second to recover from the stall then the mode switches from A.FLOOR to TOGA LOCK (TOGA LK). ![]() When the angle of attack (alpha) is approaching a stall condition then the auto-thrust system turns on automatically in the ALPHA FLOOR (A.FLOOR) mode and commands full TOGA thrust to prevent the stall. At the minimum descent altitude disengage the autopilot and land manually.The FINAL vertical mode will arm and once you intercept the final approach segment the FINAL APP mode engages, combining the APP NAV and FINAL modes. Push the APPR button to arm the approachĪPP NAV will arm and engage once you are on the route.Deselect the LS system display on the PFD as we won’t be needing it.Fly along the route with NAV mode and descent to the initial approach fix altitude.To use an RNV approach you first have to select it in the navigation menu or via the MCDU or MFD in the cockpit. This accuracy is not high enough to perform an automatic landing but with these approaches the airport doesn’t need to have an ILS installed on the runway that you want to land.ĭuring a managed approach the autopilot uses the flight management system computed navigation route and vertical path and steers the aircraft to stay on the planned route. So called area navigation approaches (RNV-Approaches) rely on GPS signal and triangulation of radio-navaids to compute the aircraft position to a high degree of accuracy. The autopilot is able to fly even a curved and sloped approach fully automatically.
