Figure 3-6: Altitude, Baro, and Vertical Speed Display Features
Altitude Digital Readout
The altitude digital readout is located in the center of the altitude tape and
displays the current baro-corrected altitude in feet above mean sea level
(MSL). The readout can show a minimum of - 1,500 feet and maximum of
35,000 feet. A left justied minus sign is shown when altitude is less then
zero. Striped boxes are shown in place of leading zeros for the thousands
and ten thousands digits.
Metric Altitude Digital Readout
The metric altitude digital readout is located on the right side of the
display above the altitude digital readout. The readout has a black
background surrounded by a white box with white digits. The readout
provides baro-corrected altitude in meters and has a range of -456
to 10,668 meters. A left justied minus sign is shown when altitude is
less than zero.
Altitude Invalidity
The altitude tape and readout is removed from the display and
replaced with an altitude failure message ‘ALT’ when invalid altitude
data is detected. See Chapter 4 for details.
