weather theoryFAA-published sample question (IRH, Aug 2021)
When approaching a cumulonimbus cell that is on your route of flight, a pilot should
A
circumnavigate the cell by at least 20 nautical miles.✓ Correct Answer
B
descend to an altitude that will allow the aircraft to fly under the cell.
C
fly under the anvil to protect the aircraft from violent parts of the cell.
Explanation
AIM 7-1-27 advises avoiding any thunderstorm identified as severe or giving an intense radar echo by at least 20 miles. Flying under the cell or under the anvil exposes the aircraft to turbulence, wind shear and hail.
