PFD Operation
4-14 SkyView HDX Pilot’s User Guide – Revision B
Magnetic Heading Indicator/ Directional Gyro
The Magnetic Heading Indicator/ Directional Gyro is displayed on the lower center of the PFD
and incorporates a magnetic heading compass rose, magnetic heading digital display, turn rate
indicator, ground track GPS pointer, heading bug, and heading bug digital display. Figure 39 is
an example SkyView Magnetic Heading Indicator/ Directional Gyro.
The compass rose displays in heading-up orientation. The cardinal points are displayed as
letters, and 30-degree increments are displayed numerically, in 10 degree multiples, (e.g., 330
degrees is displayed as 33). The numeric display at the top of the compass rose indicates
magnetic heading. If magnetic heading is unavailable, for example due to a magnetometer
failure, GPS ground track is displayed at the top, as shown below.
