All Magnetic Headings are displayed in degrees. The value range is from 001° - 360°,
always displayed in three digits, and use leading zeros when applicable. The Magnetic
North is expressed as 360°.
4.4.1. Compass
The PFD oers two Compass Modes: 360°, CDI, and ARC CDI. The Compass Mode is 360.
The aircraft’s heading is always expressed degrees magnetic. The magnetic headings
inside of the compass scale omit the last zero for brevity (i.e., 30°, 60°, 120°, 150°, 210°,
240°, 300°, and 330° are labeled 3, 6, 12, 15, 21, 24, 30, and 33, respectively). The four
cardinal compass headings are shown as letters (i.e., N for 360°, E for 090°, S for 180°, and
W for 270°).
4.4.1.1. 360° Compass Mode
The 360° Compass Mode displays a full 360° compass rose with all other components
of the Direction Indicator. The 360° compass rose rotation centers on the aircraft
ownship symbol so that the numerical direction indication corresponds to the current
aircraft heading (Figure 4-40).
4.4.1.2. ARC Compass Mode
The ARC Compass Mode has an abbreviated 100° ARC compass scale. All other
elements of the Direction Indicator are retained. The ARC Compass Mode’s scale
rotation centers on the aircraft ownship symbol so that the numerical direction
indication corresponds to the current aircraft heading. The default ARC Compass Mode
is ARC CDI.
