Bearing is the compass direction from the present position to a destination waypoint.
Desired Track is the recommended direction to steer in order to reduce cross-track error
and return to the course line.
The Course Deviation Indicator, or needle, indicates the aircraft’s distance off course,
left or right, based on its placement along the course deviation scale.
Manually selecting 0.25 nm, 1.25 nm, or 5.00 nm full-scale deflection overrides Auto
CDI selection. The manually-selected CDI scale setting remains active until conditions
are met for Auto CDI (below), at which time Auto CDI resumes. The active course
deviation scale (either automatically- or manually-selected) displays on the upper right
portion of the HSI. The default CDI scale setting is Auto CDI (not user-selectable),
which is selected when applying power to the system. Auto CDI uses three factors to
determine the distance from the center of the CDI to full left or right limits:
• CDI scale = 1.25 - within 30 nm of any airport in the active route.
• CDI scale = 0.25 - on an approach leg or within 2 nm of the FAF or MAP.
• CDI scale = 5.0 - if the previous two conditions are not met.
