If the selected altitude information fails, an ALT SEL flag appears.
(13) V/S flag (red)
If the vertical speed information fails, the V/S flag replaces the vertical speed scale.
(14) LOC and G/S flags (red)
If the localizer or glideslope receiver fails, a LOC or G/S flag appears on the deviation scale.
(15) V/DEV flag (red)
If the vertical deviation information fails, and the ILS pushbutton is not pressed, a V/DEV flag
replaces the V/DEV scale.

(16) RA flag (red)
If both radio altimeters fail, this flag appears in place of the radio height indication.
(17) DH flag (amber)
A DH flag appears, when the aircraft reaches the selected DH.
(18) HDG flag (red)
If the heading information fails, the HDG flag replaces the heading scale.
(19) CHECK HDG flag (amber)
The CHECK HDG flag appears, as does an ECAM caution, if there is a discrepancy (5 °)
between pilots’s, and copilot’s heading indications.
(20) MACH flag (red)
This flag appears, if the Mach data fails.
(21) V/DEV (amber)
At the top of the glide scale, this message flashes when FINAL mode is armed/engaged, and
the ILS pushbutton is selected.
(22) DME 1 flag (red)
When the DME distance is not valid, a DME1 (on PFD1) or DME2 (on PFD2) flag replaces the
DME distance indication.
(23) ILS1 flag (red)
If an ILS frequency fails, or if either the LOC or G/S signals fail, an ILS1 (on PFD1) or ILS2 (on
PFD2) flag replaces the ILS frequency indication.
(24) WINDSHEAR warning (red)
This message is displayed, when windshear is detected (reactive windshear warning) by the
FAC.
The detection function is available, when slats/flaps are extended as follows :
‐ At takeoff, from 5 s after lift-off, up to 1 300 ft RA.
‐ At landing, from 1 300 ft RA down to 50 ft RA,
After windshear detection, the message is displayed for at least 15 s, and is associated with an
aural “WINDSHEAR” warning, which is repeated 3 times.
(25) W/S AHEAD
This message is displayed, when the predictive windshear system has detected windshear
ahead of the aircraft.
The message is in amber or red, depending on the alert level.
Refer to DSC-34-60-30 WINDSHEAR ALERTS inhibition

Note: 1. All flags, except SI, V1 INOP and DME 1 (which are steady), flash for 9 s, then are
steady.
The DH flag flashes for 3 s, then is steady.
2. For information on the TCAS flag, Refer to DSC-34-80-10 TCAS MODES.
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
