Metric Altitude Readout
BARO Set Readout
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.
