An adjacent, magenta Altitude Trend Vector predicts the anticipated
altitude, in the next six seconds, if the current rate of climb or decent is
maintained. Like the VSI, there is a slight lag in the indication. If the ribbon
meets or exceeds the display limit, the vertical trend is large. The Altitude
Trend Vector does not display when the altitude remains constant.
If the altitude exceeds 51,000 feet, the Numerical Altitude Value is dashed,
and the tape is frozen at this limit. All altitude information is removed and
replaced with a red X with the textual annunciation of ALT FAIL when
altitude data is invalid (Figure 4-15).
4.2.3.1. Barometric Units of Measure
Barometric units of measure adjustment may be made in either inches of
mercury (in) (Figure 4-16) or millibars (mB) (Figure 4-17), as congured
by the pilot in the Menu. The adjustment range is 28.10 – 30.99 inches
Hg or 946 – 1049 mB. The barometric pressure default value is 29.92
inches, or as previously set.
Set Barometric Units of Measure
1. Press the MENU Button.
2. Rotate the Right Knob to select the GENERAL SETTINGS B page
(Figure4-18).
3. Press the BARO Menu Key.
The Menu label turns magenta, and the EDIT VALUE label displays above
the Right Knob (Figure 4-19).
4. Rotate the Right Knob to select either in or mB (Figure 4-20).
5. Press the MENU Button to exit.
