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.
Attitude
The attitude indication displays the airplane pitch and roll attitude referenced to
the horizon.
Pitch attitude is displayed by an airplane symbol against a pitch scale. The pitch
scale is in 2.5º increments.
A pointer indicates bank angle in increments of 10º, 20º, and 30º. Single marks
indicate 45º and 60º of bank. A small rectangle under the bank angle pointer
indicates slip and skid conditions. Bank angle is also represented by the attitude
of the airplane symbol against the horizon line and pitch scale.
A pitch limit indication is displayed at low speeds when the flaps are up and at all
times when the flaps are down.
Steering Indications
The flight director steering indications are displayed when the associated flight
director switch is on.
TCAS resolution advisories are displayed in the attitude indication area. (Refer to
TCAS PFD Vertical Guidance
in Chapter 15, Section 10, for additional
information.)
The flight path vector (FPV) symbol represents airplane flight path angle
vertically and drift angle laterally. The flight path vector is displayed on the PFD
when the EFIS control panel FPV switch is selected on, or the MCP FPA reference
switch is selected on. The FPV shows the Flight Path Angle (FPA) above or below
the horizon line and drift angle left or right of the pitch scale’s center. The FPA
uses inertial and barometric altitude inputs. The vertical FPA is unreliable with
unreliable primary altitude displays.
The flight path angle (FPA) symbol shows the selected flight path angle when the
MCP FPA reference switch is selected on and either the flight director or autopilot
is engaged.
