Takeoff and landing reference speeds and flap maneuvering speeds are shown
along the right edge of the speed tape. Maximum and minimum airspeeds are also
displayed along the right edge of the speed tape.
CAUTION: Reduced maneuver capability exists when operating within the
amber regions below the minimum maneuvering speed or
above the maximum maneuvering speed. During non-normal
conditions the target speed may be below the minimum
maneuvering speed.
Altitude
Altitude is displayed on an altitude tape along the right side of the PFD. It is also
shown digitally in a window in the middle of the tape. An altitude trend vector
indicates predicted altitude in six seconds.
When meters is selected on the EFIS control panel:
• current altitude in meters is also shown above the altitude window
• selected altitude in meters is displayed above the altitude tape
Selected altitude is displayed above the altitude tape and is boxed when
approaching the selected altitude. Selected altitude is also depicted with a bug on
the altitude tape.
The selected barometric approach minimum is indicated on the altitude tape with
a triangular pointer and green line.
A landing altitude reference bar is displayed along the inner edge of the altitude
indication. The reference bar indicates the height above touchdown. A white bar
is displayed from 1000 to 500 feet above landing altitude. An amber bar is
displayed from 500 feet to the landing altitude.
The current barometric reference is displayed below the altitude tape. A
preselected barometric reference can be displayed when STD is displayed.
Landing reference is selectable between QNH and QFE on the APPROACH REF
page of the FMC. QNH is the normal operating mode. Selecting QFE sets the
destination landing altitude indication to zero altitude. With the landing reference
set to QFE, changing the barometric setting from STD to QFE changes the PFD
altitude tape background color to green. With QFE selected and climb mode
active, changing the barometric setting from QFE to STD causes the landing
reference to toggle from QFE to QNH and the altitude tape background color
changing from green back to normal. (Refer to Approach Reference Page
in
Chapter 11, Section 43, for additional information.)
