NG COWL ANTI ICE

[Pin Head]

Hi

Had this caution appear last week for no aparant reason.

In the climb, fairly light weight, icing conditions.

Any thoughts on what triggered this, sticky valve?

Difficult to follow NNC in the climb s flight conditions didn't allow. Tried VS and CLB 1 to se if that helped.

Thoughts?

Thank you

It's an overpressure situation sensed:
(disconnect auto throttle and) reduce power on affected engine until light goes out...

You may end up asymmetric a little but this should prove no problem.

Right at the top of the NNC...
