g. Landing. Extreme care must be exercised
when landing on ice or slippery runways. Excessive
use of either brakes or power may result in an
uncontrollable skid. Ice accumulation on the aircraft
will result in higher stalling airspeeds due to the
change in aerodynamic characteristics and increased
weight of the aircraft due to ice buildup. Approach and
landing airspeeds must be increased accordingly.
8-60. ICING (SEVERE).
a. The following weather conditions may be
conducive to severe in-flight icing:
1. Visible rain at temperatures below 0
ambient air temperature.
2. Droplets that splash or splatter on impact
at temperatures below 0
C ambient air
b. The following procedures for exiting a severe
icing environment are applicable to all flight phases
from takeoff to landing:
1. Monitor the ambient air temperature.
temperatures as cold as 18
vigilance is warranted at temperatures
around freezing with visible moisture
2. Upon observing the visual cues specified
in the limitations section of this manual for
the identification of severe icing conditions,
Paragraph 5-35, accomplish the following:
a. Immediately request priority handling
from air traffic control to facilitate a
route or an altitude change to exit the
severe icing conditions in order to avoid
extended exposure to flight conditions
more severe than those for which the
aircraft has been certified.
