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

Well in my FCOM it is not related. The WAI is under the check:
WING ANTI ICE.....OFF

so... =)

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.
