feet. So, for example, if the aircraft is 4 NM away from the airport
and descended to 150 feet AGL, a climb to 270 feet AGL must be
completed to clear the condition.
EXCESSIVE DESCENT RATE (EDR)
The function that monitors for excessive rates of descent is always
active, not just in the vicinity of an airport. There is a caution area for
high rates of descent and a warning area for even higher rates of
descent. The figure below depicts the yellow caution area in which a
“Sink Rate” aural alert and associated yellow caution CAS message
is issued an
d then a red warning area in which a “Pull Up” aural alert
and associated red warning CAS message is issued.
The excessive rate of descent aurals will continuously repeat every 6
seconds until either the message is acknowledged or the condition is
no longer valid.
The “Pull Up” warning will provide up to 24 seconds of protection,
while the
“Sink Rate” caution will provide up to 33 seconds of
protection, based on aircraft altitude. Aircraft vertical speed and
current terrain elevation below the aircraft are used to compute the
alerting altitude thresholds. As a result, these protection times may
not apply in rising terrain or when the aircraft’s rate of descent is
increasing.
