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 identied
in the Aircraft Flight Manual. They have a range between two speeds that are pre-set at
installation as outlined in Table 5-11 and shown in Figure 5-18.
Speed markers are also pre-set during installation, indicating important aircraft-specic
speeds, where applicable. The textual Vspeed labels are made pilot adjustable or locked
during the PFD installation.

Speed Bands
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.
