The Landing Flaps monitor provides the flight crew with
awareness of possible unstabilized approach due to flaps not
in landing configuration. This function, if enabled, provides a
"Flaps (pause) Flaps" callout if the landing flaps are not set
at 950ft AFE (typical upper Flap gate). A "Flaps Flaps" (no
pause in between) call is provided if the aircraft is aligned
with the runway and the landing flaps are still not set at 600ft
AFE (typical lower Flap gate). Note that there is an effective
450 foot lower limit where the "Unstable" voice would take
precedence.
According to pilots from several major airlines who fly large
air transport jets in the U.S., Europe and Asia, the landing
flaps are typically set before the aircraft reaches 1,000ft AGL
except during a circling approach. The landing flaps are not
set until the aircraft is on base during a circling approach.
Since Stabilized Approach Monitor does not know the
destination runway set in the FMS, Stabilized Approach
Monitor can issue a "Flaps-Flaps" callout during a circling
approach, most likely on downwind leg. If this becomes an
issue, the function can be disabled by the RCD.
Although the existing EGPWS Mode 4 envelope is already
covering the landing flaps callout (i.e., "Too Low Flaps"
callout at 245ft radio altitude), some operators commented
that pilots need to be advised at much higher altitude from a
stabilized approach point of view. Therefore, Stabilized
Approach Monitor is designed to provide a landing flaps
callout independent from Mode 4.
Crew briefing for an engine-out approach without normal
landing flaps set should include the potential Flaps Flaps alert
and appropriate use of Flap over-ride or inhibit control if
available.
Crew briefing for a circling approach with a low circling minima
(e.g., <1000 ft) should include the potential Flaps Flaps alert
before the circling procedure begins and appropriate use of Flap
over-ride or inhibit control if available.
The Excessive Speed monitor provides the flight crew with
awareness of possible unstabilized approach due to excessive
approach speeds. This function, if enabled, provides a "Too Fast
– Too Fast" callout if the aircraft approach speed becomes too
fast compared to the target approach speed (V
pilots are often asked by ATC to maintain high speed during the
final approach, the excessive speed envelope is designed to allow
greater deviation from the target approach speed at higher
altitude.
