Weather Mapping and Interpretation
LIGHTNING AND STATIC DISCHARGES
Lightning and static discharges could scatter the display momentarily.
However, the general presentation is unaffected and should return to
normal within 1 scan.
Above all, remember: Never regard any thunderstorm as LIGHT, even
when radar observers report the echoes are of light intensity. Avoiding
thunderstorms is the best policy.
• DON’T attempt to preflight plan a course between closely spaced
echoes.
• DON’T land or take off in the face of a thunderstorm in the projected
flight path. A sudden wind shift or low level turbulence could cause loss
of control.
• DON’T attempt to fly under a thunderstorm even if you can see through
to the other side. Turbulence under the storm could be severe.
• DON’T try to navigate between thunderstorms that cover 6/10 or more
of the display. Fly around the storm system by a wide margin.
• DON’T fly without airborne radar into a cloud mass containing scattered
embedded thunderstorms. Scattered thunderstorms not embedded
usually can be visually circumnavigated.
• DO avoid by at least 20 nautical miles, any thunderstorm identified as
severe or giving an intense radar echo. This is especially true under the
anvil of a large cumulonimbus.
• DO clear the top of a known or suspected severe thunderstorm by at
least 10,000 feet altitude. This may exceed the altitude capability of the
aircraft.
• DO remember that vivid and frequent lightning indicates a severe
thunderstorm.
• DO regard as severe any thunderstorm with tops 35,000 feet or higher
whether the top is visually sighted or determined by radar.
