1. A method for enhancing situational awareness onboard an aircraft during an aircraft ground maneuver, the method comprising:
- increasing the depth of the field-of-view of a three dimensional flight deck display element in response to the aircraft attaining a speed that exceeds a predetermined speed;
displaying airport features that fall within a first predetermined distance from the aircraft when the aircraft is taxiing below a predetermined speed;
increasing the area displayed to a second predetermined distance from the aircraft in accordance with aircraft speed such that, when the aircraft exceeds the predetermined speed, the second predetermined distance increases according to (i) a step function or (ii) a linear function in combination with a step function; and
increasing the second predetermined distance in relation to the distance travelled by the aircraft in a predetermined period of time.

Abstract
A method and apparatus is provided for enhancing situational awareness onboard an aircraft during an aircraft ground maneuver such as when taxiing on a runway or taxiway. A three-dimensional view including airport features is rendered in a first airport region that extends a first predetermined distance (D1) from the aircraft when the aircraft speed is less than a predetermined speed (V1). A three-dimensional view including airport features in a second airport region is rendered that extends beyond D1 when the aircraft speed exceeds V1.

7. A method for displaying a dynamic synthetic view of an airport moving map on a flight deck display system on an aircraft, comprising:
-
receiving airport feature data; receiving aircraft speed data; rendering on the display system a three-dimensional view including airport features in a first airport region that extends a first predetermined distance (D1) from the aircraft when the aircraft speed is less than a predetermined speed (V1); rendering on the display a three-dimensional view including airport features from the first airport region and airport features in a second airport region that extends to a second predetermined distance (D2) from the aircraft when the aircraft speed exceeds the predetermined speed (V1), wherein (i) the second predetermined distance is greater than the first predetermined distance and (ii) the second predetermined distance is related to the speed of the aircraft as (a) a step function or (b) a combination of a linear function and a step function; and increasing the second predetermined distance by a distance travelled in a predetermined period of time at the current aircraft groundspeed. - View Dependent Claims (8, 9, 10, 11)

12. A flight deck display system, comprising:
-
a first source of airport feature data; a second source of aircraft speed data; a third source of aircraft position data; a display element; and a processor operatively coupled to the first, second, and third sources and to the display element and configured to (1) access the first, second, and third sources;
(2) render on the display element a three-dimensional view including airport features in a first airport region that extends a first predetermined distance (D1) from the aircraft when the aircraft speed is less than a predetermined speed (V1); and
(3) render on the display a three-dimensional view including airport features in the first airport region and a second airport region that extends a second predetermined distance (D2) from the aircraft when the aircraft speed exceeds the predetermined speed (V1);
wherein a relationship between D2 and V1 comprises one of (i) a step function, and (ii) a linear function in combination with a step function; and
wherein D2 is greater than D1; andwherein the processor is further configured to increase the second predetermined distance (D2) by a distance travelled by the aircraft in a predetermined period of time at a current aircraft groundspeed.
