Selected Altitude Readout
The selected altitude readout is always located above the altitude tape between two horizontal
lines. Negative altitudes are displayed with a minus sign in place of the one thousand digit.
The selected barometric altitude is always displayed with a minimum of 3 digits. The selected
metric altitude is displayed with a minimum of one digit and the indication is rounded to the nearest
50 meters.
The selected metric altitude readout on the HUD may disagree with the PFD selected metric
altitude readout upon initial selection. On intial selection the HUD displays the metric altitude
rounded to the nearest 50 meters, while the PFD displays the actual metric altitude. The HUD and
PFD will synchronize to the nearest 50 meters when the altitude selector is moved.
Selected Altitude Bug
The selected altitude bug is displayed on the altitude tape in the appropriate position when within
the range of the altitude displayed. When the selected altitude is off range, the altitude bug is
located at the appropriate end of the altitude tape and half of the symbol is masked.

Radio Altitude Readout
The Radio Altitude readout is located below the FPV and is not displayed with the airplane weight
on wheels. The range is between 0 and 2550 feet and is displayed as follows:
· 2 feet increments − Altitude less than 10 feet
· 5 feet increment − Altitude between 10 feet and 200 feet
· 10 feet increment − Altitude between 200 feet and 1500 feet
· 50 feet increment − Altitude greater than 1500 feet

VNAV Target Altitude Readout
The VNAV target altitude readout is displayed at the left of the altitude tape when one of the
following FD submodes is active:
VALT
VASEL
VFLC
VPTH
Low Altitude Awareness
The low altitude awareness indication is displayed as an indication to alert the crew of the
proximity of the airplane to the ground.
The low altitude awareness indication is displayed as a bold tape that extends from the bottom of
the altitude tape to a position that corresponds to the terrain altitude, based on radio altitude.

Airspeed Tape
The airspeed tape displays the current indicated airspeed derived from the pilot selected MADC
with a range of ±40 kt from current airspeed. The airspeed indication has a total range of 30 to
900 kt.
To enable greater lateral movement of the FPV under strong crosswind condition, the airspeed
tape moves outboard to the edge of the display thus maintaining the FPV in conformal view.
Airspeed Readout
The airspeed readout is located in the value window in the center of the airspeed tape. The
airspeed readout is displayed in 1 kt increments and has priority over the airspeed tape and all
symbology.
Airspeed Trend Vector
The airspeed trend vector indicates the airspeed the airplane will attain in 6 seconds assuming the
current acceleration is maintained.
Selected Airspeed Readout
The selected airspeed readout is located above the airspeed tape between two horizontal lines. It
has a resolution of 1 kt and has a range of 0 kt through 900 kt inclusively. The Selected Airspeed
is displayed when:
· Indicated Airspeed is valid, and
· Selected Airspeed is valid, and
· IAS FMS/Man indicates Manual, and
· Selected Airspeed Type is IAS and less than VMO.
NOTE
VMO is displayed when the selected airspeed is at VMO.
