Avoidance Maneuvers - Honeywell IntuVue RDR-4000 Pilot's Manual

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 (see page 15).

In areas where the REACT field is shown, expect the possibility of
weather that may need to be avoided (see page 16).

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 40 for more information).

Consider the height of a storm cell when planning avoidance.
Avoid all green, yellow, red, and magenta areas of cells taller than
o
28,000 ft by at least 20 nm.
Cells exceeding 35,000 ft should be considered extremely
o
hazardous and additional separation (in addition to the 20 nm)
should be used.
