4.14. F/O's Primary Flight Display Flags (PFD)(A320)

SPD Sel FlagIndicates failure of selected speed data.

V1 INOP Flag

Indicates V1 signal is not valid.

SI FlagIndicates loss of side slip data.

Check ATT FlagIndicates at least a 5 discrepancy in attitudedata between PFDs. Appears on both PFDs inamber.

ALT SELIndicates selected altitude data failure.

Check ALT FlagAppears in amber when the differencebetween both PFD's altitude indications isgreater than 250 feet (QNH), or 500 feet(STD). Inhibited when CAPT and F/O ADRbarometric references disagree.

SPD FlagIndicates speed data failure.

FD FlagIndicates both FMGCs have failed or both FDs

have disengaged with FD switches on.

ATT Flag

Indicates attitude data failure.

FPV FlagIndicates drift angle or flight path angle are not

valid when in TRK-FPA mode.

G/S FlagIndicates Glide Slope receiver failure.

ALT FlagIndicates altitude data failure.

V/S FlagIndicates Vertical Speed data failure.

V/DEV FlagIndicates Vertical Deviation data failure andILS switch not pushed.

DH FlagIndicates in amber that decision height hasbeen reached.

RA FlagIndicates failure of both radio altimeters.

LOC FlagIndicates failure of Localizer receiver.

SPD LIM FlagAppears when both FACs are inoperative.Indicates the following speed data is lost: VLS,

S, F, green dot, VTREND, VMAX OP, VMAX,VFE NEXT, VSW.

MACH FlagIndicates Mach data failure.

ILS FlagIndicates ILS frequency is not available or thatboth localizer and glide slope signals havefailed.

DME FlagIndicates DME distance is not available.

HDG FlagIndicates Heading data failure.

Check HDG FlagIndicates at least a 5 discrepancy in Headingdata between PFDs. Appears on both PFDs inamber

.

4.15. F/O's Navigation Display Flags (ND)(A320)

VOR Course FlagIndicates VOR course data failure in red.

Check HDG FlagAppears inamber when a discrepancy of atleast 5between both NDs is detected by theflight warning computer (FWC).

HDG FlagIndicates heading data failure in red. Flashesfor the first nine seconds.

LOC FlagIndicates localizer data failure in red. Flashesfor the first nine seconds.

Center Message Area

MODE Change - Appears ingreen when a discrepancy is detectedbetween the selected mode on theEFIS control panel and the mode sentfrom the on-side FMGC, or while anew page is being prepared by theDMC for display. Has priority over"RANGE Change" message.

RANGE Change - Appears ingreen when a range discrepancy isdetected.

MAP NOT AVAIL - Appears inred when "CHANGE" message isdisplayed more than six seconds, or to

indicate FMGC failure, or to indicatethat the airplane position provided byFMGC is not valid.

VOR FlagIndicates VOR bearing is not valid. Flashes forthe first nine seconds.

G/S FlagIndicates G/S data failure in red. Flashes forthe first nine seconds.

VOR/ADF/DME FlagIndicates failure of a navigation receiver in red.Flashes for the first nine seconds.

Other Message AreaIndicates incomplete map data. If the numberof images exceeds capacity, the FMGC mightshed some optional data from the display.

4.16. F/O's Forward Panel(A320)

GPWS - G / S GPWS - Illuminates red when any

GPWS mode from 1 through 4 isactivated and an aural warningsounds.

G / S - Illuminates amber when GPWSmode 5 is activated and the "GlideSlope" aural warning sounds. Pressingthe switch silences the "Glide Slope"warning and turns off the G/S light.

ND Brightness Control KnobManually adjusts on-side ND brightness. Outerknob controls the brightness of the weatherradar image only. Inner knob controls thegeneral brightness of the ND symbology.

PFD/ND XFR SwitchInterchanges the on-side PFD and NDdisplays.
