Aircraft systems and methods that determine, based on location data from a navigation system, whether conditions have been met enabling arming of an approach mode of an autopilot system. The systems and methods, when the one or more conditions enabling arming of the approach mode are determined to be met, start a first timer of a first period of time and, at the same time, provide a first message to alert a pilot to arm the approach mode via manual input to a user interface. When a determination has been made that the approach mode continues to have not been armed via manual input to the user interface, the approach mode is automatically armed.
