16
Q

Flight into limited icing condition

A

a positive air temperature band must exist at an altitude of at least 500ft above the surface to deice

17
Q

RIPS degradation

A

Aircraft may transition as long as power req to maintain level flight less than 81% and no more than 10% above the value cruise performance chart

If need more than 81% / 10% heli must descent to deice prior to continue

18
Q

Limitations limited icing conditions

A

1: Engine inlet anti-ice
2: Pitot heat
3: Windshield anti-ice
4: Ice rate system
5: OAT system

19
