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. 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. 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deg/sec, an arrowhead appears at the end of the magenta trend vector and the prediction is no longer valid.

BEARING POINTERS AND INFORMATION WINDOWS
NOTE:
When the Arc HSI is displayed, the Bearing Information windows and pointers are disabled.
Two bearing pointers (the second of which is an optional feature) and associated information can be
displayed on the HSI for the NAV, GPS, and ADF sources. The bearing pointers are light blue and are single-
line (BRG1) or double-line (BRG2). A pointer symbol is shown in the information window to indicate the
navigation source. The bearing pointers never override the CDI and are visually separated from the CDI by a
white ring. Bearing pointers may be selected but not necessarily visible due to data unavailability.
