Mode 1 provides alerts for excessive descent rates with respect
to altitude AGL and is active for all phases of flight. This mode
has inner and outer alert boundaries as illustrated in the
diagram and graph below.
Penetration of the outer boundary activates the EGPWS caution
"SINKRA TE SINKRA TE"
"SINKRA TE"
"PULLUP"
lights and "SINKRATE, SINKRATE" alert enunciation.
Additional "SINKRATE, SINKRATE " messages will occur for
each 20% degradation.
Penetration of the inner boundary activates the EGPWS
warning lights and changes the audio message to "PULL UP"
which repeats continuously until the inner warning boundary
is exited.
Note: "Pull Up" may be preceded by "Whoop, Whoop" in
some configurations based on the audio menu option selected.
If a valid ILS Glideslope front course is received and the aircraft
is above the glideslope centerline, the outer (sinkrate)
boundary is adjusted to desensitize the sinkrate alerting. This
is to prevent unwanted alerts when the aircraft is safely
capturing the glideslope (or repositioning to the centerline)
from above the beam.
