Flight in limited icing is
approved
Flight into limited icing condition
a positive air temperature band must exist at an altitude of at least 500ft above the surface to deice
RIPS degradation
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
