Maximum Speed (NP, AI, AII, AIII)
Bottom of bar indicates the maximum speed as limited by the lowest of the following:
.
Vmo/Mmo
.
landing gear placard speed
.
flap placard speed.
Inhibited on the ground.
Maximum Maneuvering Speed (NP, AI, AII, AIII)
At high altitudes and flaps up, the bottom of the bar indicates the airspeed that provides a 0.3 g maneuver margin to high speed buffet. May be displayed at high altitude with flaps up, at relatively high gross weights.
When flaps are not up, bottom of the bar indicates flap limit placard speed for the next normal flap setting. The display logic is based on a normal flap setting sequence of 1, 5, 15, 30. The bar is removed when the flap lever is moved to the landing flap selected on the APPROACH REF page or when the flap lever is moved to flaps 30 or 40.
Speed Bug (NP, AI, AII, AIII)
Points to the airspeed:
.
manually selected in the IAS/MACH window
.
indicates the FMC computed airspeed when the IAS/MACH window is
blank.
When the selected speed is off scale, the bug is parked at the top or bottom of the tape, with only one half bug visible.
Minimum Maneuver Speed (NP, AI, AII, AIII)
Top of bar indicates minimum maneuver speed.
Minimum Speed (NP, AI, AII, AIII)
Top of bar indicates the speed at which stick shaker occurs.
Inhibited on the ground.
Ground Speed (all modes)
Indicates current ground speed in one knot increments.
