5 - ALTITUDE TREND VECTOR
− Color: magenta
− The altitude trend vector represents the altitude that the airplane
should attain in 6 seconds if the current altitude rate (Vertical
Speed) is maintained.
− Displayed as a vertical bar that extends from the center of the
altitude tape upward for positive vertical speeds and downward
for negative vertical speeds.
6 - LOW ALTITUDE AWARENESS
− Color:
− band: brown
− limiting line: yellow
− Provided through a raster band that will be displayed on the bottom
of the altitude tape in case the radio altitude is below 550 ft.
− Covers the lower half of the altitude tape when the airplane is
on ground.
7 - BAROMETRIC ALTITUDE CORRECTION DISPLAY
− Color:
− digits: cyan
− label: white
− Ranges from 542 to 1083 hPa (16.00 to 32.00 inHg) with a
resolution of 1 hPa (0.01 inHg).
8 - BARO KNOB
− Allows setting barometric altitude correction value.
− Rotating clockwise or counterclockwise increments or
decrements barometric altitude correction.
9 - STANDARD BUTTON
− Adjusts barometric altitude correction to standard setting
(29.92 inHg or 1013.25 hPa).
10 - IN/HPA BUTTON
− Selects barometric pressure unit between inches of mercury
(inHg) and hectopascals (hPa).
