FLIGHT INSTRUMENTS
Turn Rate Indicator
The Turn Rate indicator resides directly above the ro-
tating compass card. Each tick mark is at 9 (half standard
rate tick mark) and 18 (standard rate tick mark) degrees
to the left and right of the lubber line. A wide magenta
line displays the current turn rate, up to 24 degrees. A
magenta arrowhead appears at 25 degrees and disappears
at 24 degrees. This trend vector provides the pilot with
a 6 second prediction of what the heading will be at the
present turn rate.

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 (enroute 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).
