Further to the above. R.E minimum speed tape. The min and max manuever speed indications are those that the FMC may output commands to the auto-pilot system for aircraft control.
Speed Tape Data
The following FMCS data shows on the airspeed tape:
Minimum Manuever Speed shows as an amber line which begins
at the minimum manuever speed on the tape and extends to the
stick shaker speed. Minimum manuever speed is the lowest speed
the FMC may use for control signals.
Maximum Maneuver Speed shows as an amber line which begins
at the maximum maneuver speed on the tape and extends to the
maximum operating speed. Maximum Maneuver speed is the
maximum speed the FMC may use for control signals.
Decision Speed (V1) shows as a green V1 and digital readout at
the top of the tape when the value of V1 is off-scale. When the
value of V1 is within the range of the scale, V1 shows next to
the decision speed on the tape.
Rotation Speed (VR) shows as a green VR next to the rotation
speed on the tape, or as R when within four knots of the
decision speed.
Landing Speed (V REF) shows as a green REF next to the
landing speed on the tape.
Flap Manuever Speeds show as green digits next to the speed at
which a flap setting applies. Flap retraction to zero units shows as
UP.
Selected Target Speed shows as a magenta readout at the top of
the tape and a magenta cursor on the tape. This data normally
comes from the AFDS, but comes from the FMCS when VNAV
is engaged.
