HEADING AND COURSE INDICATIONS
See the AFCS Section for more information on Selected Heading functions.
NOTE:
A digital reading of the current magnetic heading appears on top of the HSI. The heading displayed on the
HSI is always magnetic, even if the Navigation Angle (NAV ANGLE) is set to 'True' on the AUX - System Setup
Page on the MFD (see the System Overview for details).
When the pilot selects a course by rotating the CRS Knob, a digital reading appears for 3 seconds in a box
to the right of the lubber line, next to the HSI. While the HSI is displayed as an arc, the Selected Course
is displayed whenever the Course Pointer is not within the 140˚ currently shown Pressing the CRS Knob
displays the digital reading, re-centers the CDI, and returns the course pointer pointing to the bearing of the
active waypoint or navigation station (see OBS Mode for information on adjusting a GPS course).
When the pilot selects a heading by rotating the HDG Knob, a digital reading appears for 3 seconds in a
box to the left of the lubber line, next to the HSI. A rotatable heading bug marks the desired heading on the
HSI. While the HSI is displayed as an arc, if the Selected Heading Bug is adjusted off the shown portion of
the compass rose, the digital reading displayed. This Selected Heading Bug and the current aircraft heading
can be synchronized by pressing the HDG Knob, which moves the bug to the current heading.
TURN RATE INDICATOR
The Turn Rate Indicator is located directly above the rotating compass card. Tick marks to the left and right
of the lubber line denote half-standard and standard turn rates. A magenta Turn Rate Trend Vector shows the
current turn rate. The end of the trend vector gives the heading predicted in 6 seconds, based on the present
turn rate. At rates greater than 4 deg/sec, an arrowhead appears at the end of the magenta trend vector and
the prediction is no longer valid (Figure 2-17).
A standard-rate turn is shown on the indicator by the trend vector stopping at the standard turn rate tick
mark, corresponding to a predicted heading of 18˚ from the current heading (Figure 2-18).
