AVOIDANCE MANEUVERS
When considering avoidance maneuvers keep the following in mind:
• Never deviate under a storm cell or the associated anvil.
• Plan deviations on the upwind side of storm cells to avoid turbulence
generated downwind of convection, which may not be detectable by
the radar.
• When flying between storm cells allow at least 40 nm separation.
• Damaging hail can be thrown at least 20 nm from the storm cell by
upper level winds.
• Avoid all yellow, red, or magenta areas, particularly if they can be
associated with convective activity.
• Avoid any cells associated with Hail or Lightning Icons by a minimum
of 20 nm.
• In areas where the REACT field is shown, expect the possibility of
weather that may need to be avoided (see page 17).
• Establish an avoidance plan before getting within 40 nm of the cells
to allow time to negotiate a deviation with ATC. (See PLANNING A
PATH on page 42 for more information).
• Consider the height of a storm cell when planning avoidance.
o Avoid all green, yellow, red, and magenta areas of cells taller than
28,000 ft by at least 20 nm.
o Cells exceeding 35,000 ft should be considered extremely
hazardous and additional separation (in addition to the 20 nm)
should be used.
