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 six 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no longer valid.

(rate > 4 deg/sec)
A standard-rate turn (3 deg/sec) is shown on the in-
dicator by the trend vector stopping at the standard turn
rate tick mark, corresponding to a predicted heading of 18
degrees from the current heading.

Course Deviation Indicator
The Course Deviation Indicator (CDI) moves left or
right from the course pointer along a deviation scale to
display aircraft position relative to the course.
The CDI has the same angular limits as a mechanical
CDI when coupled to a VOR or LOC. When coupled
to GPS, the full scale limits for the CDI are defined by a
GPS-derived distance (5.0, 1.0, or 0.3 nm). The CDI scale
automatically adjusts to the desired limits based upon the
current phase of flight (en route: 5.0 nm, terminal area:
1.0 nm, or approach: 0.3 nm). The desired GPS scale set-
tings may be selected manually from the MFD (refer to the
Multi Function Display section).
