"LDG DIST PROC... APPLY" - a320 question

[Superpilot]

From my own notes and in line with the new FCOM/QRH:

Approach speed corrections and landing distance factors:
(Use with an ECAM message LANDING DISTANCE PROC… APPLY)

1.) From QRH ABN-80.16, (Dry) or 80.7 or 80.18 (Wet or Contam.) and if Landing Distance Summary table not available (otherwise everything should be on QRH page with the failure), obtain a.) Flaps Position, b.) ∆VREF, c.) LDG DIST Factor

2.) To work out Landing Distance, obtain distance from QRH FPE-IFL 2/4 (Without Autobrake CONF FULL), multiply by LDG DIST Factor and any additional factors (1.1 or 1.2, Anti Ice, A/T) from Vapp table (in 3)

3.) Using Vapp Calculation table, QRH ABN-80.14, obtain APPR CORR (VREF = VLS in CONF Full from Perf page)

4.) Insert Vapp into Perf page, and only after this select CONF 3 on Perf page. However, be careful. For any subsequent failures requiring the same procedure to be repeated, you must revert to CONF FULL on Perf page before entering new Vapp speed, then select CONF 3 again.


I would like to hear from others if this approach is wrong or long winded. Thanks
