Methods and apparatus are provided for displaying terrain and attitude data symbology for an aircraft. The apparatus is a hybrid centered head-down display for an aircraft having a monitor configured to generate a display and a processor coupled to the display. The display has a centerline. The processor is configured to calculate a displayed drift angle limit, a displayed drift angle, align the centerline of the display with reference to the displayed drift angle, and generate on the display a first symbol corresponding to a terrain and a second symbol corresponding to an attitude of the aircraft. The processor is further configured to center the first symbol and the second symbol with reference to the centerline.

What is claimed is: 1. A method for displaying information on a hybrid centered head-down display of an aircraft, the aircraft having a track angle, a heading angle, and an attitude, said method comprising the steps of: determining a present flying state of the aircraft and calculating a displayed drift angle limit in response; calculating a displayed drift angle having a value less than or equal to the displayed drift angle limit; aligning a centerline of the display between the track angle and heading angle with the track angle offset from the centerline by the displayed drift angle; generating a first symbol on the display, the first symbol corresponding to a terrain; generating a second symbol on the display, the second symbol corresponding to the attitude; and centering the first symbol and the second symbol with reference to the centerline. 2. The method of claim 1, wherein the step of calculating a displayed drift angle limit includes calculating a continually decreasing displayed drift angle limit in response to a flight condition requiring increased attention to the direction of aircraft movement. 3. The method of claim 2, wherein the step of calculating a displayed drift angle limit includes calculating a continually decreasing displayed drift angle limit in response to one of a high bank condition, a terrain obstacle, aircraft traffic, and a weather condition. 4. The method of claim 1, wherein the step of calculating a displayed drift angle limit includes calculating a continually increasing displayed drift angle limit to provide awareness of track and heading directions. 5. The method of claim 4, wherein the step of calculating a displayed drift angle limit includes calculating a continually increasing displayed drift angle limit in response to one of a level flight condition and a runway approach. 6. The method of claim 1, wherein the step of calculating a displayed drift angle limit includes operator selection of the displayed drift angle limit. 7. The method of claim 1, further comprising the step of generating a third symbol on the display, the third symbol corresponding to a track of the aircraft. 8. The method of claim 1, wherein said centering step comprises laterally centering the first symbol and the second symbol with the displayed drift angle. 9. The method of claim 8, further comprising the steps of: generating a third symbol on the display, the third symbol corresponding to a flight path of the aircraft; and laterally centering the third symbol with the track of the aircraft. 10. A hybrid centered head-down display system for an aircraft having a track angle, a heading angle, and an attitude, said head-down display system comprising: a monitor configured to generate a display of a view in front of the aircraft, said display having a centerline; and a processor coupled to said monitor and configured to: determine a displayed drift angle limit in response to a present flying state of the aircraft; determine a displayed drift angle, said displayed drift angle having a value equal to or less than said displayed drift angle limit and having a value between the track angle and the heading angle; align said centerline of said display between the track angle and the heading angle wherein the track angle is offset from the centerline by the displayed drift angle; and generate on said display: a first symbol representing a terrain as viewed in front of the aircraft, said processor further configured to position said first symbol with reference to the centerline; and a second symbol representing the attitude, said processor further configured to align said second symbol with reference to the centerline. 11. The system of claim 10, wherein said displayed drift angle limit is continually decreasing in response to one of a high banking condition, a terrain obstacle, aircraft traffic, and a weather condition, thereby providing increased awareness of the track of the aircraft. 12. The system of claim 10, wherein said displayed drift angle limit is continually increasing in response to one of a level flying condition and a runway approach, thereby providing increased awareness of crab conditions. 13. The system of claim 10, wherein the aircraft has a flight path and wherein said processor is further configured to: generate on said display a third symbol representing the flight path; and position said third symbol with reference to the centerline. 14. The system of claim 10, wherein said processor is further configured to generate on said display a third symbol representing the heading and position said third symbol with reference to the centerline. 15. A program product for a hybrid centered head-down display of an aircraft, the aircraft having a track angle, a heading angle, and an attitude, said program product comprising: an avionics display program executable to: calculate a displayed drift angle limit in response to present flight conditions; calculate a displayed drift angle, said displayed drift angle having a value between the track angle and the heading angle, and equal to or less than the displayed drift angle limit; center the display with reference to said displayed drift angle, wherein said display includes a centerline between the track angle and the heading angle, wherein the track angle is offset from the centerline by the displayed drift angle; generate on the display: a first symbol representing a terrain as viewed in front of the aircraft; and a second symbol representing the attitude, said program further executable to center said first symbol and said second symbol with reference to said centerline. 16. The program product of claim 15, wherein the displayed drift angle limit is continually increasing in response to one of a level flying condition and a runway approach, thereby providing increased awareness of crab conditions. 17. The program produce of claim 15, wherein the displayed drift angle limit is continually decreasing in response to one of a high banking condition, a terrain obstacle, aircraft traffic, and a weather condition, thereby providing increased awareness of the track of the aircraft. 18. The program product of claim 15, wherein said avionics display program is executable to laterally center said first symbol and said second symbol with said centerline. 19. The program product of claim 15, wherein the aircraft has a flight path and wherein said avionics display program is further configured to: generate on said display a third symbol representing the flight path; and position said third symbol with reference to the centerline. 20. The program product of claim 15, wherein said avionics display program is further configured to: generate on said display a third symbol representing the heading and position; and position said third symbol with reference to the centerline.
