Altitude Alert Preselect Display; Altitude Digital Display; Barometric Altimeter Display; Low Altitude Awareness Symbol - Honeywell PRIMUS 1000 Pilot's Manual

Altitude Alert Preselect Display -- This data is displayed at the top
D
of the altitude scale. The data is set by the guidance controller
altitude select knob. The set data is cyan. When the aircraft is within
the altitude alert operating region, the box around the set data turns
from white to amber. The set data also turns amber. When a
departure from the selected altitude occurs, the select display box
also changes from white to amber.
The altitude alert operating region is defined as that time when the
aircraft enters the region where it is within 1000 feet of the
preselected altitude during a capture maneuver. At this time the box
around the set data turns to amber. Once the aircraft is within 250
feet of the preselected altitude, the box turns back to cyan. After
capture, the aircraft re--enters the altitude alert operating region if it
departs more than 250 feet from the selected altitude. A momentary
audio alert is sounded when the aircraft is 1000 feet from the
preselected altitude or has departed 250 feet from the select altitude
after capture.
Altitude Digital Display -- A digital display of the actual altitude
D
value is contained in the display window. This data is a magnification
of the digits on the scale and is readable to within a 20--foot
resolution. The digits within the pointer are green. Below 10,000
feet, boxed
ten--thousand--foot digit is missing.
Barometric Altimeter Display -- The baro set display is located
D
directly below the altitude tape. The pilot can set the altimeter in
either inches of mercury (inHg) or hecto Pascals (hPa) as selected
with the PFD bezel controller. If the on--side DC is invalid, the SG
defaults to the last selection (In or hPa). The baro set data is always
cyan.
Low Altitude Awareness Symbol -- At radio altitudes of 550 feet
D
or less, the lower part of the altitude tape linearly changes from a
gray raster to brown and the altimeter scale markings are removed.
At zero radio altitude, the brown raster touches the altimeter
reference line.
Altitude Analog Scale -- The altitude tape is a moving scale display
D
with fixed pointer. The scale markings on the tape are labeled in
500--foot increments. The scale digits are arranged with the larger
numbers at the top. The scale and its markings are white. The
500--foot tick marks are enhanced below 10,000 feet.
