VR Bug
The reference marker is a cyan line followed by an R. The VR bug is the rotation speed
reference. The bug display is automatically removed after the V2 speed is exceeded.
V2 Bug
The reference marker is a cyan line followed by a 2. The V2 bug is the takeoff safety speed
reference. The bug display is automatically removed after the V2 speed is exceeded (V2 + 40
knots + weight off wheels for 7 seconds).
VT Bug
The reference marker is a cyan line followed by a T. The VT bug is the target speed reference.
IAS Reference Field
The magenta display shows the selected IAS reference value. The value is marked by the
notched-box (bucket) symbol on the IAS scale. Turn the SPEED knob on the FCP to set this
value. While in Mach mode, turning the SPEED knob then sets a magenta selected Mach
number at the top of the IAS scale, and corresponding moves the notched-box symbol on the
IAS scale.
IAS Reference Marker
The magenta notched-box symbol is the IAS reference marker. The IAS reference marker is
always selected for display and is set by the SPEED knob on the FCP. While in Mach mode,
the IAS reference marker corresponds to the selected Mach number set in the reference field
at the top of the IAS scale..

Altitude Displays
Barometric Altitude Display
The display simulates a rolling drum mechanism and is outlined by a white window. The
present barometric corrected altitude displayed is the sum of the numeric “thousands” readout
and the “hundreds” moving tape indication at the window. If barometric altitude data becomes
invalid, the altitude displays are replaces with a red ALT annunciation.
NOTE
A metric barometric altitude readout may also be displayed below
the pressure display. This boxed readout with an “M” label displays
the barometric altitude in meters.
Fine Barometric Altitude Scale
The fine barometric altitude scale is a vertical “moving tape” display. The display window range
is 450 feet. The scale contains a line marking every 20 feet and a numeric label every 100 feet.
The scale moves down for increasing altitude.
Coarse Barometric Altitude Scale
The coarse barometric altitude scale is a non-numbered vertical “moving tape” display that
helps visualize (preselected) altitude captures. Large rectangles on the scale represent
1,000-feet altitude increments, and small rectangles represent 500-foot increments. The
display window range is 2,250 feet. The scale moves down for increasing altitude.
Barometric Pressure Display
Barometric pressure correction is numerically displayed in either inches of mercury or in
hectopascals (hPa). The correction value and format are set by the on-side ADRP.
Preselect Altitude Display
The preselected altitude is numerically displayed in magenta above the barometric altitude
scales. The ALT knob on the FCP sets the value.
NOTE
A metric preselected altitude readout with an “M” label may also be
displayed below the normal displays. The boxed readout displays
the preselected altitude in meters.

Preselect Altitude Bug
The ALT set knob on the FCP is used to set the preselected altitude value. The preset altitude
is displayed on the top of the altitude scale in magenta, and as a window on the coarse and
fine altitude scales.
This four-line marker displays on the coarse and fine barometric altitude scales to mark the
preselected altitude value. The marker is always in view on the coarse barometric altitude
scale and then shows on the fine barometric altitude scale when in range.
The preselected altitude display and bug both change colors and/or flash as the airplane
acquires a preselected altitude. These displays are normally magenta. Both displays flash
magenta when the airplane approaches the preselected altitude, and then become steady
again at altitude capture.
