Maximum Speed (PRI in flight mode)

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 (PRI in flight mode)

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.

Points to the airspeed:

• manually selected in the IAS/MACH window

• indicates the FMC computed airspeed when the IAS/MACH window is

blank.
