Radio Altitude
The current radio altitude is displayed in the bottom center of the attitude
indication area when radio altitude is below 2,500 feet AGL. The display turns
amber when the radio altitude is below the radio altitude minimums.
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. 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 a line when BARO minimums are selected. When RADIO
minimums are selected, the pointer is still set at BARO minimums but there is no
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.
A landing altitude indication is displayed as a crosshatched area and indicates:
• the FMC landing altitude for destination runway or airport, or
• the landing altitude for departure runway or airport until 400 NM from
departure or one–half the distance to destination, whichever occurs first.
The current barometric reference is displayed below the altitude tape in either
inches of mercury or hectopascals as selected on the EFIS control panel. A
preselected barometric reference can be displayed when STD is displayed.
Vertical Speed
Vertical speed is displayed to the right of the altitude tape with a tape and pointer.
Vertical speed is digitally displayed above or below the vertical speed display
when vertical speed is greater than 400 feet per minute. It is displayed above with
positive vertical speed and below with negative vertical speed. The selected
vertical speed bug shows the selected vertical speed when in the AFDS vertical
speed (V/S) pitch mode.
