1. A system for providing airport surface operation information to an aircraft pilot in conformal, non-conformal or combined conformal and non-conformal views, comprising:
- a display including a symbol generator mounted in the aircraft;
a computer coupled to the display;
a position determination device mounted in the aircraft and coupled to the computer that provides information of the aircraft position with respect to the surface of the earth;
an electronic database that includes detailed airport information that can be accessed by the computer; and
an aircraft ground speed sensor for providing an input signal to the computer for determining aircraft ground speed when the aircraft is operating on the surface of the earth;
wherein the display provides a variety of aircraft location and authorized non-runway ground movement guidance information to the aircraft pilot, while the aircraft is located on the surface of the earth, in either a conformed view, a non-conformed view, or both conformed and non-conformed dependent upon a calculated pilot view from the aircraft windshield, as determined by aircraft location, aircraft heading, traffic route information with respect to aircraft location, aircraft, on the ground, operating speed and current non-runway ground movement clearances.

10. An enhanced method of airport surface movement operation including an on-board aircraft situational awareness system that provides movement clearance information and precise aircraft ground location in a blended conformal and non-conformal manner, comprising the steps of:
-
Initializing the situational awareness system;
loading electronic airport ground navigational database;
determining present aircraft location;
entering aircraft movement clearance, when received from the airport surface operations controller;
generating and displaying aircraft movement guidance symbols;
monitoring aircraft location and speed;
calculating preferred ground speed for given aircraft prior to a required turn in the direction of aircraft travel;
displaying preferred ground speed of aircraft;
overlaying a conformal view of the instantaneous view out the aircraft windshield with a non-conformal view, at a predetermined time prior to entering a required turn;
updating displayed information to reflect next movement guidance clearance;
generating and displaying new guidance information; and
repeating the step of updating displayed information, until aircraft transitions to flight or parked. - View Dependent Claims (11, 12, 13, 14, 15, 16)
