EXCESSIVE DESCENT RATE (EDR)
The excessive rate of descent alerts are intended to be always
active, even 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 and 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condition is no longer valid.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 between 0 and 30 seconds of
warning depending on aircraft altitude at the time. “Sink Rate”
cautions add approximately 25% to those numbers. Aircraft
vertical speed and current terrain elevation below the aircraft are
used to compute the alerting altitude thresholds.
The Excessive Descent Rate (EDR) alert is triggered at -1600
fpm. “Pull Up” EDR warnings are the most serious/highest
priority of all TAWS alerts, even higher than FLTA warnings.
