Engine Anti-Ice (AFM)
Engine anti-ice must be on during all ground and flight operations when icing conditions exist or are anticipated, except during climb and cruise when the temperature is below -40°C SAT. Engine anti-ice must be on prior to and during descent in all Icing Cond itions, including temperatures below -40°C SAT
