Description

Section
Notes
RED
(LOW SPEED)
Low speed
awareness
2 - Limitations
If the aircraft has a defined WHITE or
GREEN arc, set the RED arc to
ON
. Set the
MAX value of the RED arc to the lowest
value of the WHITE or GREEN arc (Vs0). A
RED low-speed awareness arc will appear
below the lowest marked stall speed.
If the aircraft does not have defined white or
green arc, set the red arc to
OFF
, and enter
the lowest stall speed in the STALL SPEED
setting at the bottom of the page.
WHITE
Full flap operational
range
2 - Limitations
Set the Min value to the bottom of the POH/
AFM defined range.
If WHITE and GREEN arcs overlap, set the
Max value to the beginning of the WHITE/
GREEN arc.
If WHITE and GREEN arcs do not overlap,
set the Max value to the top of the POH/
AFM or aircraft specification defined range.
If a WHITE arc is not defined by the AFM/
POH or aircraft specifications, set both the
Min and Max values to the aircraft stall
speed in the landing configuration (Vs0).
This setting will not display a white arc, but
the system needs it to characterize aircraft
performance.
HALF WHITE
Standard operational
range
2 - Limitations
If the HALF WHITE arc range is not defined
by the AFM/POH or aircraft specification,
set to
OFF
.
This may sometimes be called a “narrow
WHITE arc”.
WHITE/
GREEN
Overlap between
standard operational
and flaps operational
ranges
2 - Limitations
If a WHITE/GREEN arc is not defined by
the AFM/POH or aircraft specification, set
to
OFF
.
If WHITE and GREEN arcs overlap,
configure to the range they overlap within.
GREEN
Standard operational
range
2 - Limitations
If the GREEN arc is not defined by the
AFM/POH or aircraft specification, set to
OFF
.
If WHITE and GREEN arcs overlap, set Min
value to the Max of WHITE/GREEN.
If the YELLOW arc is defined, set to the Min
of the YELLOW arc (Vno).
If the YELLOW arc is
not
defined, set Max
value to Vno/Vne.
