Abstract
Methods and systems are provided for indicating whether an aircraft is below a designated minimum safe altitude level for an altitude sector. A method comprises displaying a graphical representation of a first sector on a display device associated with the aircraft. The first sector corresponds to a geographic area having a first minimum altitude criterion. If a current altitude of the aircraft is below the first minimum altitude criterion, the method continues by displaying the graphical representation of the first sector using a first visually distinguishing characteristic chosen to indicate that the aircraft is below the designated altitude level for the first sector.
