(DH) or BARO altitude alert altitude values for display on the PFD. The

power-up default value is BARO OFF (dashed).

• STD Button – Pushing the STD button returns the barometric altimeter

correction to standard value of 29.92 in. Hg (1013 HPa).

• BARO SET knob – The BARO SET knob selects barometric altimeter correction.


Primary Flight Display Section [Altitude Display]

• Altitude Select Display – The

altitude alert select readout is

displayed at the top of the altitude

scale. It is set using the right-side

remote instrument controller. It’s

value displays in cyan except when

within 1000 feet of the selected

value it turns amber.

• Altitude Rolling Digits – The

altitude rolling digital display reads

current altitude in 20ft increments.

It’s value displays in green. Below

10,000 a boxed cross-hatch replaces

the left-most digit to emphasize low

altitude awareness.

• BARO Altimeter Setting – The BARO set window is under the altitude tape.

It can be set in either Inches of Mercury (in. Hg) or Hectopascals (hPa) using

the MFD bezel controller. The value displays in cyan.

• FMS VNAV Altitude Select Bug and Display – When a VNAV altitude has

been entered into the FMS, and any VNAV flight guidance mode is engaged,

the MMaaggeennttaa altitude select annuciation and bug are displayed. The digital

readout is at the top left of the altitude tape, below the flight director vertical

modes. The arrow-shaped bug is along the outer left side of the altitude tape.

• Altitude Trend Vector – The altitude trend vector originates at the altitude

reference line. It displays as a magenta thermometer shape that corresponds

to altitude rate of feet per minute. If the aircraft maintains the same vertical

speed for the next six seconds, the projected number of feet climbed equals

the number of feet at the top of the trend vector.

• Altitude Select Bug – The altitude select bug is a notched rectangle that

travels along the left inside of the altitude tape. The bug is displayed at the

altitude value set in the altitude alert select display. The bug color is the

same as the digit color in the altitude select window.

• BARO Altitude Analog Scale – The barometric altitude tape is a white

moving scale display with fixed pointer. It’s labeled in 500ft increments with

a chevron at each 500ft and 1000ft interval. The 1000ft marks show double

chevrons, the 500ft show single.

• Low Altitude Awareness Display – At radio altitudes of 550ft or less, the

lower part of the altitude tape changes from gray to brown.

• Metric Altitude Display – The metric altitude display is directly below the

BARO set data. It is shown only if it has been selected for display via the

MFDs PFD SETUP menu option. It’s value is always green.

• Barometric Altitude Alert Bug (MDA Bug) – The D-shaped altitude alert

bug is displayed on the left outside of the altitude tape, with a line extending

from the bug across the tape. Its position corresponds with the digital BARO

set value.


Primary Flight Display Section [Airspeed Display]

• VMO Overspeed Tape – VMO is a fixed

red bar that originates at VMO and

extends up to the scale end along the

right side of the airspeed tape.

• Slat/Flaps Limit Bugs – When the

airspeed tape is within the slat/flap

maximum airspeed extended range, red

bugs with white labels are displayed as

follows:

right side of the airspeed tape.

• FMS Airspeed Bug – When an FMS-supplied speed target is selected, and

any FMS VNAV flight director mode is engaged, a hollow MMaaggeennttaa arrow is

shown on the right side of the airspeed tape and the FMS speed target is

displayed above the airspeed tape.

• Mach Display – A digital display of the present Mach number is shown below

the airspeed tape. The value is displayed when Mach is greater than 0.450

(accelerating) and is removed below 0.400 Mach (decelerating).

With Mach below 0.45, the VSPEED bug values replace the MACH display window

sequentially until the VSPEED bug is displayed on the analog airspeed scale. When

on the ground, if all the takeoff (T/O) VSPEED values have not been set and

selected for display, a VSPEED annunciation (VSPD) is displayed in the window.

When the aircraft is on the ground and the IAS is less than 30 knots, the bottom

half of the airspeed tape is replaced with VSPEED values in the following order:

E Enroute

2 V2 (Takeoff Safety)

R Rotate

1 V1 (Takeoff Decision)



• Airspeed Rolling Digit Display – A rolling digit display of the current

indicated airspeed (IAS) within the display window. The digits inside the

window are GGrreeeenn. When the current airspeed is equal to or exceeds the

maximum allowable airspeed (VMO), the digits turn RReedd. When the airspeed

trend vector exceeds VMS by 1kt, the digits turn AAmmbbeerr unless a red alert

indication is required.

NOTES:

1. If the flaps are fully extended, the airspeed digits turn RReedd if that

flap/slat speed limit is exceeded, or AAmmbbeerr if the airspeed trend

vector exceeds their speed limit by 1kt.

2. When the airspeed is less than 1.1 VS, the airspeed digits turn RReedd.

3. When the airspeed trend vector enters the less than 1.1 VS area, the

airspeed digits turn AAmmbbeerr.
