Abstract: A computer system for displaying terrain, weather and aviation information includes a terrain database, an aviation map database, a weather database, an air traffic database, an airplane specific database and a route database. A processor is coupled to the terrain database, the aviation map database, the weather database, the air traffic database, the airplane specific database and the route database and configured to determine a position and heading of an airplane over the terrain based on the route database, to compute terrain information, aviation map information, air traffic information and weather information relative to the airplane and to compute and display flight parameters associated with the airplane using the airplane specific database. Advantages of the invention include the ability to supply a pilot with information that he can use to visualize his flight and approach to the destination airport.
