1. A navigation system for an aircraft having a top and at least one side, the system comprising:

  • a navigation data module to receive navigation data;

    a display to display the navigation data in a horizontal mode; and

    a controller to detect a navigation event based on the navigation data and to cause the display to automatically display the navigation data in the horizontal mode and a vertical mode, in response to the navigation event, whereinthe vertical mode includes a vertical mode aircraft symbol and the horizontal mode includes a horizontal mode aircraft symbol,the vertical mode includes lines showing gradations of altitude,the horizontal mode displays a top view of the aircraft together with a top view of Federal Aviation Administration (FAA)-defined airspace near the aircraft, the top view being from a substantially top perspective, and the vertical mode displays a side view of the aircraft together with a side view of the FAA-defined airspace near the aircraft, the side view being from a substantially side perspective,the horizontal mode displays the top view of the aircraft together with a top view of terrain near the aircraft, the top view being from a substantially top perspective, and the vertical mode displays the side view of the aircraft together with a side view of the terrain near the aircraft, the side view being from a substantially side perspective,the horizontal mode displays the top view of the aircraft together with a top view of weather near the aircraft, the top view being from a substantially top perspective, and the vertical mode displays the side view of the aircraft together with a side view of weather near the aircraft, the side view being from a substantially side perspective,the horizontal mode displays the top view of the aircraft together with a top view of terrain near the aircraft, the top view being from a substantially top perspective, and the vertical mode displays the side view of the aircraft together with a side view of other aircraft near the aircraft, the side view being from a substantially side perspective, andthe horizontal mode displays the top view of the aircraft together with a top view of an instrument landing system (ILS) approach path including a localizer center beam and a localizer pattern, the top view being from a substantially top perspective, and the vertical mode displays the side view of the aircraft together with a side view of the ILS approach path including a glide slope center beam and a glide slope pattern, the side view being from a substantially side perspective.
