OEBS And Other Temporary Faults Flashcards
OEB: Erroneous FMS predictions due to FLT PLN corruption.
Fuel prediction and remaining distance at destination different between MCDUS.
Can trigger, DEST EFOB BELOW MIN message in scratchpad.
Fuel forward transfers.
Caused by copy and change of secondary FLT plan to departure or alternate airport.
To fix
Delete SEC
Re enter CRZ FL on prog index page.
OEBs: In event of departure RWY change TO data May revert to original runway.
Happens when both MCDUS display PERF take off data.
Next phase is pressed on the other MCDU.
If this happens perform Departure runway change SOP
Loss of closest airport predictions in low density airport areas.
Clear 5th airport on closest airports page to recover full FMS predictions.
No engagement of guidance mode.
During GA SRS or GA TRK RWY modes remain engaged and other guidance modes cannot be selected or engaged as expected.
LVR CLB not displayed on FMA at THR red alt
Alt* and Alt will not capture.
AP: off.
Both FDs: off then on.
For approach that follows GA do not arm G/S mode.
Note: A/C reverts to HDG V/S modes and modes may be reengaged as appropriate.
Incorrect vertical profile after a hold not included in arrival procedure.
Alt constraints after a hold are incorrect.
Aircraft will glide along incorrect vertical profile in managed descent.
Fixed by:
Before leaving a hold or immediately after. Perform direct to RADIAL IN.
Check FLT plan A page.
Aircraft restricted to cat II manual land at KEF
EI-DAA, EI-DUZ, EI-EAV, EI-EIL
This is due to AFM limitations of the Honeywell autoland database.
In the Event of GPWS, GPS, ADS-B or SURV ROW/ROP fault, click showing internal time instead of GPS time affecting ATC and datalink procedures.
Supplementary procedures in FCOM/NORM procedures/SUPP PROC/GPS interference is useful.
Any suspected GNSS interference must be reported by ASR.
For rudder trim faults
FCTL RUDDER FAULT ECAM message or when utilising the rudder jam procedure pilots must add 15kts manually to the approach speeds in the EFB. This is done on the drop down menu of the selected runway.
