2. For TCAS, Refer to DSC-34-80-10 TCAS MODES.
(23) DME 1 flag (red)
When DME distance is not available, a DME 1 (on PFD 1) or DME 2 (on PFD 2) replaces the
DME distance indication.
(24) ILS flag (red)
If an ILS frequency is not available, or if either the LOC or G/S signals fail, an ILS flag replaces
the ILS frequency indication.

FCOM 19 AUG 10
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, CHECK (F/O) (CAPT) PFD, CHECK EWD 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 CAPT PFD (CHECK F/O PFD) message is displayed on the CAPT
PFD (F/O PFD).

(3) SI flag (red)
If the Sideslip Information (SI) is lost, the index disappears and a red SI flag appears.
(4) FPV flag (red)
In 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 the selected speed information fails, a SPD SEL flag appears.
(8) SPD LIM flag (red)
The SPD LIM flag appears when both FMGCs (flight envelope part) are inoperative, or in case
of an 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.
In case only VMAX or VLS is lost, the flag comes up on the PFD but the remaining valid
information still appears.
(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, with an associated ECAM caution, if the difference between the
altitude indications on the two PFDs is greater than 250 ft when QNH is selected, or greater
than 500 ft when STD is selected.
The caution and the flag disappear, when the Captain’s and the First Officer’s barometer
references are different.
(12) ALT SEL flag (red)
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 vertical deviation information fails and the LS pushbutton is not pressed, a V/DEV flag
replaces the V/DEV scale.
(16) RA flag (red)
If both radio altimeter fail, this flag appears in place of the radio height indication when aircraft
altitude is below the transition altitude. The ground reference indication (red ribbon) will
disappear.
(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 glideslope scale this message flashes when FINAL mode is armed or engaged
or a non-ILS approach has been entered, and the LS pushbutton is selected.
(22) WINDSHEAR (red) or W/S AHEAD (red or amber) warnings
WINDSHEAR : Reactive windshear warning. Displayed, when the FMGC detects
windshear.
