D615Z003-TBC 10.12.7
Displays current flight path angle and drift angle during flight:
• flight path angle is depicted by the flight path vector symbol position on
the pitch scale
• drift angle is represented by the perpendicular distance from the line drawn
through the center of the pitch scale to the center of the flight path vector
symbol
• shows as dashed lines instead of solid lines when limited laterally by other
symbology or the display field-of-view.
Displays current heading.
Has tic marks every 5º and labels every 10º representing the heading value.
Current heading is located at a point on the horizon line where a line drawn
perpendicular to the horizon line goes through the center of the airplane symbol.
HUD Radio Altitude Indications
Referenced to the flight path vector symbol. The radio altitude indication
maintains a set distance directly below the flight path vector symbol:
• displays below 2,500 feet AGL
• is boxed for 10 seconds after descending through 2,500 feet AGL
• is boxed when descending below radio altitude minimums. Box blinks for
2 seconds, then is steady.
