A320 Wai Q
Hi,
Came across this...
FCOM 3.03.18 P4 - Standard Operating Procedures - ILS APPROACH
WHEN LANDING GEAR IS DOWN:
• Switch WING ANTI ICE ON only in severe icing conditions.
Why does gear selection influence the use of WAI?
Thanks

I don't know where you have your FCOM from, but I could imagine that it is performance related. If you are OEI and you gear is down, maybe your performance is not sufficient anymore with wing AI on?

I can only imagine that your company decided to associate WAI deselection during final with L/G extension.
Airbus proc extract:
-FLAPS FULL SELECT
Select FLAPS FULL below VFE.
-CONFIRM/ANNOUNCE "FLAPS FULL"
Check deceleration towards VAPP.
-A/THR CHECK IN SPEED MODE OR OFF
-WING ANTI ICE OFF
Only switch the WING ANTI ICE to ON, in severe icing conditions.
For Airbus, it comes after Flaps extension.
I don't think that it's related to OEI condition as you quote FCOM 3.03.18, normal procedures.
