SEL
Used to alternately
select V1, VR or V2
to the edit field
when VSPDS is
selected.
PUSH / SET / OFF
Used to adjusts the selected speed
readout displayed on the edit field.
When pushed, the selected speed
readout is displayed.
When rotated, the selected speed
readout is adjusted.
When pushed again, the selected
speed readout is removed.
RA TEST
Used to initiate
radio altitude test.
HPA / IN
Used to alternately
select the barometric
pressure to be
displayed in
hectoPascals or
inches of mercury.
BARO
Used to adjust
barometric pressure.
When pushed, the
barometric pressure
is set to the standard
value of 29.92 inHg
or 1013 hPa.
When rotated, the
barometric pressure
setting is adjusted.

DH / MDA
Used to select decision height or
minimum descent altitude.
DH -- Decision height readout is
selected to be adjusted.
MDA -- Minimum descent altitude
readout is selected to be adjusted.
TGT / VSPDS
Used to select target or V speeds.
TGT -- VT speed is selected to
be displayed on the edit field.
VSPDS -- V1, VR and V2
speeds are selected to be
displayed on the edit field.
Alternate selection of V1, VR
and V2 is made using SEL.
PUSH / SET / OFF
Used to adjust selected altitude readout.
When pushed, the selected altitude readout
(DH or MDA) is displayed on the PFD.
When rotated, the selected altitude readout
is adjusted (DH in 1--ft. increments, MDA in
10--ft. increments).
When pushed again, the selected altitude
readout is removed.

Indicated Airspeed and Mach Indications <MST>
Figure 12---30---5
IAS Bug (magenta)
Indicates airspeed reference marker as set
by pilot using the speed knob on flight
control panel.
Indicated Airspeed Tape (white)
Moving tape that indicates current airspeed.
Tape range is 40 to 400 knots with a display
of 80 knots.
Marks at 5 knot increments.
Digits at 20 knot increments.
Trend Vector (magenta)
Indicates predicated airspeed
within next 10 seconds.
Indicated Airspeed Pointer (white)
Indicates current airspeed.
IAS /Mach Reference (magenta)
Indicates airspeed as selected
using the speed knob on flight
control panel.
Mach Readout (white)
Indicates Mach speed.
Displayed when Mach is
above 0.45 and is removed
when Mach is below 0.40.
Overspeed Cue (red/black checkerboard)
Assends from Vmo/Mmo to top of tape
window to indicate maximum speed allowable.
If speed is more than 3 kts greater than Vmo
or equivalent Mmo, overspeed clacker sounds.
Warning continues until speed is 3 kts below
Vmo/Mmo.
Low Speed Cue (red/black checkerboard)
Descends from stick shaker speed to edge of
tape window and acts as cue to impending
stall speed. Displayed 3 seconds after lift--off.
If AOA data fails, checkerboard stops at 100 kts.
and is replaced by a yellow line up to 120 kts.

Speed Reference Bugs (cyan)
Removed 7.5 seconds after speed

1 Takeoff decision speed (V1)
R Rotate airspeed (VR)
2 Take--off safety speed (V2)
T Target speed (VT)
Stall Speed Indicator (green line)
Indicates 1.25 times the computed stall speed.
Displayed in flight only.
