Altitude Values

The numeric labels and major tick marks are shown

at intervals of 100 feet. Minor tick marks are at intervals

of 20 feet. The current altitude is displayed in the black

pointer.

Altitude Reference Bug

The Altitude Reference Bug is displayed at the reference

altitude or the edge of the tape (whichever is closer to the

current altitude) to provide increased altitude awareness.

To set the Altitude Reference Bug:

Turn the

ALT

knobs to set the Altitude Reference

Bug. The

small ALT

knob sets the hundreds and

the

large ALT

knob sets the thousands. This

altitude also appears in the Altitude Reference

Box above the Altimeter.

Altitude Trend Vector

This vertical, magenta line extends up or down the

altitude scale located left of the numeric labels. The end

of the trend vector displays approximately what altitude

will be reached in six seconds if the current rate of vertical

speed is maintained. The trend vector is absent if altitude

remains constant, or if any data needed to calculate it is

not available due to a system failure.

Altitude Reference Box

The Altitude Reference Box displays the reference

altitude in feet. The metric value, when selected, is

displayed on top of the Altitude Reference Box.

NOTE: The Altitude Reference Box is not part of

the autopilot altitude preselect system and is

used to aid the pilot in altitude control.

Barometric Setting Box

The Barometric Setting Box displays the barometric

pressure in inches of mercury (in Hg) or hectopascals

(hPa).

To select barometric pressure:

Turn the large BARO (outer) knob to select

the desired setting.
