Heads-Up Display Modes 35 - Metaboli

42 Heads-Up Display Modes
Basic A-10 HUD Symbology
• The heading scale appears along the bottom edge, displaying the heading
rounded to the nearest ten (for example, 270 appears as 27).
• The digital airspeed display on the right edge shows the Indicated Airspeed
(IAS) in knots.
• The digital altitude display on the right edge shows the aircraft’s altitude
above sea level (MSL) in feet.
• The digital pitch display appears below the altitude display on the right side
of the HUD, showing the aircraft’s exact pitch angle.
• The velocity vector moves through the middle of the HUD, showing the
direction the aircraft is actually moving, which varies from where the aircraft is
heading because of momentum, sideslip, angle of attack, etc.
• The pitch scale appears in the middle of the HUD, centered on the velocity
vector. Primarily, it shows the aircraft’s pitch measured in five-degree
increments. The entire scale moves left and right, however, mirroring the turnand-slip
indicator on the ADI. As with the turn-and-slip indicator, to stop
sideslip, apply rudder toward the scale.
3.202 Navigation Mode
As the name implies, navigation mode provides navigation and steering cues.
Basic navigation mode points the way to the next steer point within the
programmed route. ILS mode, on the other hand, provides information required
during landings.
