“LOC2” #2 GS/LOC Receiver tuned and shows on left-side PFD
“FMS” Single FMS installation: FMS is navigation source and shows
on left-side PFD
“FMS1” Dual FMS installation: #1 FMS is navigation source and shows
on left-side PFD
“FMS2” Dual FMS installation: #2 FMS is navigation source and shows

Lateral Deviation (CDI): Lateral Deviation is displayed on the HSI as a
conventional Course Deviation Indicator (CDI). Displacement of the CDI
with respect to its null position at the center of the ±2 dot scale is the
indication of the current lateral deviation during ILS, VOR, or FMS
operation.
Vertical Deviation Scale and Pointer: During ILS or FMS operations,
Vertical Deviation is displayed as a pointer against a vertical scale on the
right side of the display just inside and centered on the Altitude Scale.
Displacement of the Vertical Deviation Pointer from its center position on
the ±2 dot scale, indicates the current vertical deviation. When the NAV
source is LOC, the pointer is a diamond. When the NAV source is FMS, the
pointer is an asterisk (“*”).
DME/FMS Distance: DME/FMS Distance is displayed in the lower left
corner of the display. The distance is displayed in 0.1 nautical mile
increments between 0 and 99.9 miles, and in one nautical mile increments
above 99.9 miles. The distance is from the DME when the NAV source is
VOR or LOC and from the FMS waypoint when FMS is selected. The
distance is followed by “NM” or “H” for a “HOLD” mode.
Marker Beacons: Flying over a marker beacon is shown by the boxed
letters “OM”, “MM”, “IM” for Outer Marker, Middle Marker, and Inner
Marker, respectively. Each of the symbols flashes above the Aircraft
Reference Symbol.
Heading Source: The current Heading Source shows above the HSI. This
symbol gives the heading source, which is identified by one of the sets of
characters that follow:
Symbol Status
“MAG” Normal
“MAG1” Both on 1
“MAG2” Both on 2
“TRU” Normal
“TRU1” Both on 1
“TRU2” Both on 2
If the heading source is not valid, the Heading Source symbol is boxed.
