FLIGHT MODE ANNUNCIATOR
Applicable to: ALL
For a detailed discussion of legends and messages that may appear during FMGS operations, (Refer
to STLO-22_30_R-10 GENERAL).
ALTITUDE ALERT
Applicable to:
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 FCU.

FCOM 19 AUG 10
Selecting a new altitude, or pushing the ECAM’s EMER CANC ‐ pushbutton, or pressing either
MASTER WARN pushbutton, cancels the continuous C chord.
‐ Selecting a new altitude stops the flashing of the altitude window.
‐ The altitude alert is inhibited :
• When the slats are out, with the landing gear is 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 (amber)
“CHECK ATT” appears, when there is a disagreement (of a least 5 °) between the attitude
information displayed by the two PFDs. The CHECK ATT flag appears on both PFDs, and a
caution appears on the ECAM.
(3) SI flag (red)
If the sideslip information is lost or any reverse is deployed in flight, the index disappears and a
red SI flag appears.

(4) FPV flag (red)
In the TRK FPA mode, when the drift angle or flight path angle is not valid, an FPV flag
appears.
(5) FD flag (red)
If both FMGCs fail, or if both FDs are disengaged and the FD pushbutton is on and the attitude
is valid, a red FD flag appears.
(6) SPD flag (red)
If the speed information fails, a SPD flag replaces the speed scale.
(7) SPD SEL flag (red)
If selected speed information fails, a SPD SEL flag appears.
(8) SPD LIM flag (red)
This flag appears when both FACs are inoperative, or in case of SFCC dual flap/slat channel
failure.
In this case, the following PFD information is lost : VLS, S, F, Green Dot, Vtrend, VMAX, VFE
next, VSW.
(9) V1 INOP flag (red)
When the V1 signal is not valid, a V1 INOP flag replaces the digital value.
(10) ALT flag (red)
If the altitude information fails, the ALT flag replaces the altitude scale.
(11) CHECK ALT flag (amber)
The CHECK ALT flag appears, as does an ECAM caution, if the disagree between the two
PFD altitude indications is greater than 250 ft when QNH is selected, or 500 ft when STD is
selected.
The caution and the flag disappear, when the Pilot's and the Co-pilot's barometer references
disagree.
(12) ALT SEL flag (red)
