Brg (Bearing) Knobs; Navigation Bearing Pointers; Ra (Radio Altitude) Knob/Test Button - Honeywell PRIMUS 1000 Pilot's Manual

BRG (Bearing) Knobs -- The HSI can display two independent
D
bearing pointers. The selectable bearing sources for each pointer
are described in table 4--2.
BRG
FMS is optional.
NOTE:
RA (Radio Altitude) Knob/TEST Button -- These two concentric
D
controls are used to set RA minimum altitude setting (outer knob),
and to run the TEST function (inner button).
When the TEST button is pushed, the on--side PFD and MFD enter
the test mode. In the test mode, flags and cautions are displayed
along with a check of the radio altimeter. The EICAS also displays
a test pattern when the integrated avionics computer (IAC) that is
driving the EICAS page is in test. Normally, this is the left IAC.
NOTE: Once airborne, only the radio altimeter is tested but not if
the flight director has captured an ILS glideslope.
A detailed description of the display test results is contained in EFIS
Preflight Checklist, later in this section.
