5-4-7 Flight in Icing Conditions - Maximum Rate of Climb
The use of Flaps 30° is prohibited in or into known icing conditions. After icing encounters, and
with visible ice accretion on the airframe, a climb is performed with the flaps retracted and a
climb speed based on the schedule as given in
Table 5-4-7-1 .

The total climb performance is calculated by first computing the Rate of Climb in non-icing
conditions from
Fig. 5-3-3-6 (standard units) or Fig. 5-3-3-7 (metric units) and then correcting
the Rate of Climb in or into known icing conditions by using the corrections in Table 5-4-7-2
(with operational pneumatic de-ice boots) or Table 5-4-7-3 (with the pneumatic de-ice boots
inoperative).
