Abstract: The present disclosure provides an air line displaying method and a ground station. The method includes: displaying a first air line view, the first air line view including height information of at least one waypoint in an air line; when detecting a first operation performed by a user on a waypoint of the at least one waypoint, adjusting height information of the waypoint; and sending adjusted height information of the waypoint to an aircraft. By adjusting the air line view through human-computer interaction, the air line view displayed by the ground station can be edited. This makes it convenient for the user to adjust the air line and further enables the aircraft to receive a new air line in time, thereby facilitating flight of the aircraft.
