variable.) A bezel around each PFD contains
controls for operating the PFD.
Display Color-Coding
Color-coding on the displays indicates common
meanings to the pilot. These colors and
their meanings are:
• Cyan—Pilot adjustable
• Green—Active
• White—Armed/standby
• Amber—Caution
• Red—Warning
• Magenta—GPS derived
GRAPHICAL FLIGHT
INSTRUMENTATION
The following flight instruments are depicted
graphically on the PFD:
• Airspeed display
• Altitude
• Attitude display including turn coordination
(slip/skid)
• Horizontal situation indicator (HSI)
(heading, turn rate, and radio navigation)
• Vertical speed
NOTE
If the aircraft exceeds normal flight
attitudes (30° nose-up or 20° nosedown
pitch, or roll greater than 65°
bank), the PFD declutters leaving
the primary flight instruments.
Airspeed Display
The airspeed is displayed as a vertical scale
on the left side of the PFD (Figure 16-6).
Moving Tape Display Box
White numerals and tick marks on a transparent
rolling-tape display box indicate airspeeds
currently above and below the current airspeed.
Each small tick mark represents 5 knots,
and each large tick mark (with a number) represents
10 knots.
Airspeed Pointer
The airspeed (in KIAS) appears as a rolling numeric
display (white numbers on black) in the
center of the airspeed tape. This tape has a
pointer, which always points at the center of
the airspeed display. Below 20 KIAS, the digits
change to dashes. Once the airspeed reaches
and/or exceeds VMO or MMO, the pointer
changes to red with white numbers.
Trend Vector
On the outside right edge of the tape, a magenta
trend vector indicates predicted airspeed
in 6 seconds at the current rate of
airspeed acceleration. When the trend vector
enters the barber pole range, the numbers inside
the airspeed pointer change from white
to amber.
Speed Awareness
Airspeeds above the maximum operating speed
appear in the high-speed awareness range represented
on the airspeed tape by a red/white
“barber pole” (Figure 16-7) The flap speed
references represent the airspeed limits when
the aircraft is below 18,000 feet. A red lowspeed
awareness range extends up from the
bottom of the tape to indicate VLSA.

Airspeed References
Airspeed references, or flags, appear on the
outside right edge of the tape display fixed to
their corresponding airspeed (Table 16-2).
Takeoff and landing speed flags can be displayed
and adjusted in the reference window
using the TMR/REF softkey. Takeoff references
are automatically turned off when airspeed
reaches 160 kt (see Figure 16-6).
A reference approach speed cue appears as
an open green circle on the right edge of the
tape display. The open green circle represents
1.3 VS1 (see Figure 16-6).
Flap Speed References
Maximum flap-extension speeds are indicated
on the outside right edge of the tape display
by reference flags similar to the V-speed flag
(Figure 16-8). Maximum speed for takeoff/approach
flaps is indicated by a flag labeled
“TA”. Maximum speed for landing flaps is indicated
by a flag labeled “LD.” The flap reference
speed flag cannot be turned off or
adjusted by the pilot.
AFCS Selected Airspeed Box and Bug
When the AFCS is set to a selected airspeed
during flight level change mode, the selected
airspeed appears in a box at the top of the display,
and a corresponding notched blue bug appears
on the inside right edge of the airspeed
display (Figure 16-9).
