PARTICULAR PROCEDURES
FLIGHT INTO KNOWN ICING CONDITIONS (4/5)
3 -- Procedures for holding, approach and landing in icing conditions :
-- Minimum recommended speeds are :
. Flaps UP 130 KIAS
. Flaps TO 110 KIAS
. Flaps LDG 90 KIAS
-- If there is ice on the unprotected surfaces of the airplane, during
flight end phase, conduct holding with the flaps up. Use flaps as
required for final approach and landing at minimum speeds noted
above.
Ice accumulation effects
When ice has accumulated on the unprotected surfaces of the airplane,
aerodynamic characteristics may be changed.
Particularly stall speeds may increase by up to :
-- Flaps UP 20 KIAS
-- Flaps TO 15 KIAS
-- Flaps LDG 10 KIAS
Correct operation of the aural stall warning may be altered by severe or
prolonged icing.
Indeed, in case of severe or prolonged icing, an ice concretion due to
refreezing around the heated stall warning may appear.
Above--recommended speeds take into account, on one side, the stall speed
increase due to profile shape deterioration and, on the other side, the weight
increase of the iced--up airplane (taking as a basis the airplane maximum
weight when not iced--up).
Rate of climb values with ice accumulation on the unprotected surfaces are to
be decreased by 10 %.
