Both engine air intakes are now being antiiced.
Note : The fan blades are not being anti-iced.
If significant engine vibration occurs due to ice
accumulation on the blades, the engine should be
accelerated to 70% N1 minimum for approximately 15
seconds prior to higher thrust operation.

As an added precaution, we will use wing antiicing.
The WING ANTI-ICE pb sw controls the wing
anti-ice system on both wings simultaneously.
Note : Use of APU bleed is not authorized if wing
anti-ice is in use.

We have called the ECAM BLEED
page for you.
Observe that :
- the “anti-ice” white indications are
displayed, meaning that the WING
ANTI-ICE pb sw has been set to ON,
- and the green triangles are
displayed, indicating that the wing antiice
valves are open.

Normal operation 26/45
Observe that 30 seconds after the WING anti-ice pb sw has
been set to ON, the wing anti-ice valve indications disappear.
This is because the wing anti-ice valves close automatically, to
prevent an overheat of the slats. This is the ground test
sequence.
At lift-off, the valves will re-open automatically, and the slats
will be heated again.
Note :Use caution when taxiing with engine anti-icing on,
because ground idle is increased.

Normal operation 27/45
You are now in cruise, clear of icing conditions.
If you do not expect the conditions to change, antiicing
systems should be switched off.
Note : if the ice detection system is installed, an
“ICE NOT DET” memo indicates that no ice has been
detected for approximately 3 minutes or more.
