What does a navigation display show?

A navigation display is specifically designed to provide critical information related to the aircraft's navigation and position. This includes the current location of the aircraft on a moving map, the planned flight path, and any waypoints that are part of the flight plan. Navigation aids such as VOR (VHF Omni-directional Range) and NDB (Non-Directional Beacon) can also be displayed, helping pilots to navigate effectively and maintain situational awareness during flight.

The display assists pilots in visualizing their route and understanding their relationship to navigational points, significantly aiding in navigation and planning during all phases of flight. This functionality is vital for ensuring a safe and efficient flight path.

Other options, while important in aviation, pertain to different aspects of flight management and monitoring. For instance, engine temperature and pressure relate to engine performance monitoring, landing gear status and fuel quantity are part of the aircraft’s systems status monitoring, and weather updates are usually shown on separate radar systems or dedicated weather displays rather than on the primary navigation screen. Thus, the navigation display's primary focus is on navigation and positional information.
