Before Start Clearance Flashcards
LOADSHEET.
PRELIM OR FINAL LOADSHEET:
CHECK.
Both crew members carefully check the Load and Trim Sheet (LTS), particularly for gross errors.
Make sure that the loadsheet data is correct:
-Correct flight
-Correct aircraft
-Basic weight and index
-Configuration
-FOB
LOADSHEET.
ZFW/ZFWCG:
CHECK/REVISE.
The PF compares the ZFW and ZFWCG with the previously entered data, and adjusts if necessary.
The PM crosschecks the ZFW and ZFWCG entered in the FMS.
LOADSHEET.
ZFW/ZFWCG:
CROSSCHECK.
The PM crosschecks the ZFW and ZFWCG entered in the FMS.
LOADSHEET.
BLOCK FUEL:
CHECK/REVISE.
The PF enters final fuel ordered as FMS BLOCK fuel on INIT B page.
- Check FMS BLOCK fuel agrees with loadsheet TO FUEL plus CFP planned taxi fuel and is in close agreement with ECAM FOB.
- Check loadsheet TOW ACT agrees with FMS TOW on INIT B page and is in close agreement with the FlySmart TAKEOFF application TOW and ECAM GW less CFP planned taxi fuel.
- Check that the takeoff CG is within LTS operational limits.
FOB:
CHECK.
- Check that ECAM fuel on board corresponds to the F-PLN.
- Check that fuel imbalance is within limits.
- Crosscheck that the sum of the FOB recorded at the end of the last flight and the fuel uplift (if any) is consistent with the current FOB. If an abnormal discrepancy is found, maintenance action is due.
FOB after refuelling, maximum abnormal discrepancy:
Up to 6 tons:
Between 6 tons and 12 tons:
More than 12 tons:
400kg.
500kg.
600kg.
FMS TO DATA CONFIRMATION.
FMS FINAL TAKEOFF PERF DATA:
CHECK.
The PF shall:
- Brief the performance data on the FMS PERF TO page.
- Brief V1 (blue) and V2 (magenta) values on top of the PFD speed scale.
- Brief takeoff configuration and associated flap retraction strategy including flap auto-retraction.
- Brief configuration requirements for close in turns (if applicable).
- Brief packs off and anti ice requirements for takeoff.
FMS FINAL TAKEOFF PERF DATA.
PM:
CROSSCHECK.
The PM shall:
- Crosscheck the performance data displayed on the PM’s EFB with the FMS PERF TO page.
- Compare Green Dot speed computed using the TAKEOFF application, then respond with “CHECKED”.
TAKEOFF DATA.
If takeoff conditions changed.
FINAL TAKEOFF PERF DATA:
RECOMPUTE.
The PF and the PM independently compute again the takeoff performance data.
TAKEOFF DATA.
If takeoff conditions changed.
FMS TAKEOFF DATA:
REVISE.
The PF revises the takeoff data in the FMS.
If the flight crew uses the optimum configuration option for the computation, they should pay specific attention to changes to the configuration of the slats/flaps at takeoff.
TAKEOFF DATA.
If takeoff conditions changed.
FMS REVISED TAKEOFF PERF DATA:
CROSSCHECK.
The PM crosschecks the performance data displayed on the PM’s EFB with the FMS PERF TO page.
TAKEOFF DATA.
If takeoff conditions changed.
EFB/MCDU GREEN DOT:
The PM compares Green Dot speed computed by the FMGS and the Green Dot speed computed using the TAKEOFF application.
A discrepancy of more than +/- 2Kts indicates a difference in the TOW used in both systems (EFB/FMGS).
