The PFD uses color speed bands, color speed markers, and textual labels to help the
pilot recall Vspeed settings and limits. The speed band markings are determined by the
Federal Regulations and correspond to the aircraft operating speeds that are identified
in the Aircraft Flight Manual. They have a range between two speeds that are pre-set at
installation as outlined in Table 4-2 and shown in (Figure 4-12).
Speed markers are also pre-set during installation, indicating important aircraft-specific
speeds, where applicable. The textual Vspeed labels are made pilot adjustable or locked
during the PFD installation.
On aircraft with flaps, setting the upper and lower thresholds of the white and/or yellow
bands to the same value disables the applicable band. When disabled, the band does
not display.
NOTE
On aircraft without flaps, the white band is disabled,
and the green band is shown full width, as there
isn’t an applicable Flap Extend (Vfe) or Full Flap Stall
(Vs0) speed. These two speeds are set to the same
speed as the No Flap Stall (Vs) speed. This gives the
white band a value of zero, effectively disabling it.
NOTE
The color speed bands and color speed markers on
the PFD Airspeed Tape are configured to match the
certified mechanical airspeed indicator.
