The following graph represents the envelope of protection provided for
Excessive Rate of Descent scenarios:
Excessive Descent Rate
Initially, the voice alert “Sink Rate” will be heard, and the yellow caution
alert annunciator lamp will illuminate. If the aircraft continues in the high
rate of descent, the “Sink Rate-Sink Rate” voice alert will be repeated at
an increasing frequency.
Should the aircraft penetrate the warning boundary, the voice alert “Pull
Up” will be heard continuously and the red warning annunciator lamp will
illuminate.
In both cases, as the pilot reacts to decrease the high rate of descent
and the aircraft flight path exits the alerting/warning envelope, the annun-
ciator lamp will extinguish and the voice alerts will cease.
Sometimes, the alerting and warning functionality for excessive rate of
descent may be overridden by the terrain “Look-Ahead” functionality.
This is normal as the “Look-Ahead” function has a higher priority in the
system alerting/warning logic. (See the Alerting/Warning Priority chart
later in this guide.)
