1fa. Responding to Icing in Different Types of CloudsIn Chapter 5 we
talked about the threat that icing presents to aviation. The first line
of defense when having to fly through icing conditions is to activate
the plane’s antiicing equipment. But pilots sometimes can also alter the
course of the flight to lessen the threat, with the appropriate action
depending on the cloud type.When icing appears to occur within
stratiform clouds, it is a good idea to change elevation upward or
downward by about 900 meters—3000 feet (Figure 6-4-1). By definition,
stratiform clouds have relatively little vertical development, so
changing altitude by that amount will likely get you out of the region
of supercooled droplets.Icing can occur rapidly and severely in
cumuliform clouds, especially in updrafts and at temperatures ranging
from −2°C to −20°C (28°F to −4°F). Because cumuliform clouds have very
substantial vertical development, changes in altitude may be a less
effective maneuver than in stratiform clouds. It is a good idea if
possible to simply fly around such clouds. Icing in cumuliform clouds
normally occurs at altitudes below about 8000 meters (about 27,000
ft).FIGURE 6-4-1 Icing. Pilots can avoid icing conditions in stratiform
