Ice Protection
Icing conditions exist when RAT +10oC or below and visible moisture in any form is present
All ant-ice/de-ice systems must be on inflight when in icing conditions
Tail de-ice must be off when RAT is below -35oC
Minimum N2 for effective wing anti-icing 75%
After icing encounter with inoperative tail boots max flaps 15oC
Wing/Engine anti-ice may be in ENG ONLY when SAT is below -40oC
And if visually verified that no ice is accumulating

ENG anti-ice must be ON during ground operations in icing conditions. EXCEPT I minute after engine ground start, if inadvertently turned on prior to 1 minute ENG anti-ice must be turned off for 2 minutes then turned back on.
If minor engine vibration felt during ground ops momentarily increase
N1 20-30% to assist ice shedding
Failure to operate ENG anti-ice in icing conditions may result in amber ENGINE CNTRL FAULT message due to ice on T2 probe
Inflight icing operations for extended time prohibited with flaps or gear extended
With failure of wing anti-ice, disconnect autopilot and maintain 160kias minimum till approach and landing
Takeoff limited to flaps 0 if type II, III or IV anti-ice fluid has been applied
