Methods and apparatus are provided for airspace navigation. Airspace
navigation information for an aircraft is displayed in a first mode, such
as, in a horizontal mode. One or more navigation events may then be
detected, such as, proximity to a terrain feature, weather, traffic etc.
The airspace navigation information for the aircraft is then displayed
using dual modes, e.g., a horizontal mode and a vertical mode. Display
parameters, such as colors, resolution, distance, scale, etc. may be set
automatically or by a user. The display may also include information,
such as avionics systems information, and communications information.
