Callout
22
In some cases a callout is stated twice (e.g., "MINIMUMS,
MINIMUMS") but in all cases a given callout is only enunciated
once per approach.
Decision Height (DH) based callouts (Approaching Minimums,
Minimums, etc.) require the landing gear to be down and
occur when descending through the Radio Altitude
corresponding to the selected DH. These also have priority over
other altitude callouts when overlapping. For example, if DH is
set to 200 and both "TWO HUNDRED" and "MINIMUMS" are
valid callouts, then only "MINIMUMS" will be called out at 200
feet AGL.
DH plus based callouts (e.g., Approaching Minimums) are only
applicable for aircraft providing a Decision Height altitude to the
EGPWS. Consequently, not all EGPWS installations can utilize
these callout options.
Due to the variety of altitude callout choices available, it is not
possible to identify every combination in this guide. Refer to an
appropriate Airplane Flight Manual or EGPWS Airplane Flight
Manual Supplement for callout identification in a specific
application or contact Honeywell.
Another feature available in the Altitude Callouts (options) is a
"Smart 500" foot callout. When selected, this callout assists
pilots during a non-precision approach by enunciating "FIVE
HUNDRED" feet in addition to any other altitude callout
discussed above. The EGPWS determines a non-precision
approach when Glideslope is greater than 2 dots deviation
(valid or not) or a back-course approach is detected.
This feature has the distinction of adding the 500-foot callout
during non-precision approaches and removing the 500-foot
callout on precision approaches when part of the callout option.
