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).

Mach Window
At the bottom of the airspeed tape display, a
window indicates the Mach number, depending
upon aircraft altitude or airspeed.
Attitude and Turn Coordination
At the center of the PFD is the attitude indication
(Figure 16-10). The amber symbol represents
the airplane, and the amber bars represent
the wingtips. The horizon line is white, with
brown (ground) below and blue (sky) above.
The horizon line indicates 0° pitch. Pitch lines
are at 2.5° intervals above and below the horizon
line and are labeled at 10° intervals. Red
chevrons indicate extreme pitch at greater than
50° nose-up or 30° nose-down (Figure 16-11).
Roll indication is provided by an arc at the top
of the display that rotates with the horizon
line. The arc has major tick marks at 30° and
60°, and minor tick marks at 10°, 20° and 45°.
Turn Coordination (Slip/Skid)
Turn coordination is indicated by a small sliding
bar (slider) under the attitude display roll
pointer (Figure 16-12). The slider deflects a
full width left or right of the roll pointer to indicate
the same condition as indicated by a ball
positioned one ball width to the left or right
of center in a conventional instrument.
Flight Director Command Bars
The single-cue command bars vertically move
together to indicate pitch commands and bank
left or right to indicate roll commands (Figure
16-13). Command bars that display as a cross
