STRIKE FINDER
DIGITAL WEATHER AVOIDANCE
Progression of Flight Path
Figure 31 (p.36),
shows that the Strike Finder system has automatically
updated the display as the aircraft has progressed on course. The cells to
the left side of the aircraft appear closer, about 90 nm but present no threat
based on present heading.The two thunderstorms ahead are now 100 nm
from the aircraft on the edge of the DANGER area. Monitor the situation and
start to develop a plan for deviation around the thunderstorms.
Planning the Deviation
Figure 32
shows that the thunderstorms repositioned on the display
zoomed to the 100 nm range view. The two thunderstorms ahead appear
at 11:30 and 12:45, positioned within the DANGER area. The distance
between them is about 60 nm.
Zooming
to a closer range will reveal more
details about storm severity and allow a more accurate determination of the
“required storm avoidance angle”
.
