Planning To Deviate

If your Strike Finder detects thunderstorms close to your intended flight path,
a deviation from your present course must be initiated. Observe the Strike
Finder closely, to determine the distance and bearing of the thunderstorm
from the aircraft.

Avoidance By Angle

The FAA Advisory Circular, Subject: Thunderstorms, recommends that you
"avoid by at least 20 miles any thunderstorm identified as severe or giving
an intense radar echo". Pilots have no direct control over distance but do
have complete control of heading. Correct heading selection will provide
the "required storm avoidance angle", needed to keep the aircraft a safe
distance from any storm activity.
