FCOM 19 AUG 10
Applicable to:
NON PRECISION APPROACH
(1) Vertical Deviation Scale and Index
The vertical deviation scale and index appear when in approach phase and the FINAL
mode is armed/engaged or a non precision approach has been entered. They are displayed
until MDA has been reached. They give the vertical deviation with respect to the trajectory
defined by the FMGC.
Each index scale graduation represents 100 ft. The range is ± 200 ft.
Note: If LS pushbutton is pressed, glide deviation has priority over vertical deviation
information.

Applicable to: ,
NON PRECISION APPROACH
(1) Vertical Deviation Scale and Index
The vertical deviation scale and index appear when in approach phase and the FINAL mode
is armed/engaged or a non precision approach has been entered. They are displayed in the
approach or go-around phase, until MDA has been reached, or the MAP or the runway has
been sequenced. They give the vertical deviation with respect to the trajectory defined by the
FMGC.
Each index scale graduation represents 100 ft. The range is ± 200 ft.
Note: If LS pushbutton is pressed, glide deviation has priority over vertical deviation
information. As long as V/DEV display conditions are met and the LS pushbutton is
selected, an amber V/DEV message flashes above glide scale.

RISING RUNWAY SYMBOL
(1) Rising Runway Symbol (magenta)
If :
‐ The localizer signal is valid,
‐ The radio altitude is available, and
‐ The yaw bar is not displayed,
at 200 ft RA the runway symbol starts from the bottom of the pitch scale. Its vertical deviation
is driven by the radio altitude and its lateral deviation by the localizer.
Note: When the rising runway option is installed, the lower line of the attitude sphere does
not move for ground reference.

Applicable to: ALL
For a detailed discussion of legends and messages that may appear during FMGS operations, see
AFS chapter (Refer to STLO-22_30_R-10 GENERAL).
ALTITUDE ALERT
Applicable to: ALL
The FWC generates an altitude warning (C chord sound, and PFD’s altitude window pulses in yellow
or flashes in amber), when the aircraft approaches a preselected altitude or flight level or when it
deviates from its selected altitude or flight level.
This warning results from a comparison between the altitude (ADIRS) and the preselected altitude
displayed on the FCU.

The continuous C chord is cancelled by selecting a new altitude, ‐ by pushing the ECAM control
panels’ EMER CANC pushbutton, or by pressing either MASTER WARN pushbutton.
‐ The altitude window stops flashing, if a new altitude is selected.
‐ The altitude alert is inhibited :
• When the slats are out with the landing gear selected down, or
• In approach after the aircraft captures the glideslope, or
• When the landing gear is locked down.

FLAGS AND MESSAGES DISPLAYED ON PFD
Applicable to:
(1) ATT Flag (red)
If the PFD loses all attitude data, its entire sphere is cleared to display the ATT flag.
(2) CHECK ATT or CHECK PFD or CHECK PFD1 (or 2) flag (amber)
“CHECK ATT” appears when there is a disagreement (of a least 5 °) in the attitude information
displayed by the two PFDs. The CHECK ATT flag appears on both PFDs, and a caution
appears on the ECAM.
“CHECK PFD” appears when the DMC detects a disagreement between the two PFDs. The
CHECK PFD flag appears on both PFDs.
When the DMC detects a discrepancy between its own computation and its displayed
information, the CHECK PFD 1(2) message is displayed on the relevant PFD.
(3) SI flag (red)
