Advanced Airframe Specific Configuration Data – Markings
YELLOW
Caution / smooth air
operational range
2 - Limitations
If the YELLOW arc is defined by the AFM/
POH or aircraft specification, set to
ON
with
Min value equal to Maximum structural
speed (Vno). Max value should be
configured to Vne, or the highest value of
Vne if variable.
If the YELLOW arc is not defined, set to
OFF
.
Vne/Vmo/Mmo
Never exceed speed/
max operating speed/
max operating mach
number
2 - Limitations
If defined as a fixed value, set to
Fixed
, and
enter POH/AFM defined Vne/Vmo as the
Min value.
If variable with altitude, set to
Variable
, and
set overspeeds in accordance with
Appendix E in
GI 275 Part 23 AML STC

twins.
Set to

for
single-engine aircraft.
RED/WHITE BAR
Varies – sometimes used as a
fixed point Vne marking
2 - Limitations
If a fixed RED/WHITE bar,
(not a barber pole) is shown
in the POH/AFM, set to given
value. Else, set to
OFF
.
WHITE TRIANGLE
