DISPLAY REVERT button on the PFDCP
if only 2 DU’s are working, what will be displayed?
one will show the combined PFD map, the other will show EICAS
If only 2 DU are working, when is the only time the EICAS won’t be shown?

when will an IBIT be disabled?
in flight
what will pushing the test button on the PFD display?
all possible information and warning fields of the display and red crosses over the airspeed and altitude fields
what will pushing the test button on the MFD display?

when will the low speed awareness warning transition to climb-cruise-descent mode?
V2+50
in climb-cruise-descent what does the low speed awareness band cover?
top: Vswarn (70)
bottom: tape limit

what does the slow speed band cover in the landing mode?
top: configurable percentage of V2
bottom: tape limit
what can the slow speed band never be adjusted above?
configured value of Vswarn used in the climb-cruise-descent mode of operation
when will no mach value display?

how do we set barometric minimums?
press RA/DA twice and turn the knob
when setting barometric minima what will a push on the PUSH SEL button do?
allow changing of the minima in single ft steps
when will the DA numerals change to amber?
when radio altitude is equal to or less than the selected DA. (returning to white upon landing or go around)
how do we set RA minimums?
by pressing RA/DA once and turning the knob
can RA and DA minimums be shown simultaneously?
no
what kind of heading is shown?
magnetic heading
what does the arrow on the heading bug show?
the shortest direction to selected heading when bug is not on selected heading
what indicates to us the FD is engaged?
red boxed FD on the PFD, but commands are not transferred to the AP if the computer has detected an internal fault.
