When confronted with an approaching thunderstorm, a take-off or landing

  1. Ashould be avoided as a sudden wind shift or low level turbulence could cause a loss of control.Correct answer
  2. Bis safe if you can see under the thunderstorm through to the other side.
  3. Cshould be avoided unless the take-off can be made away from the thunderstorm.
  4. Dis safe if the thunderstorm is regarded as light.

Why this is the answer

Thunderstorms produce violent wind shear, gusts and low-level turbulence (TC AIM-AIR), so a take-off or landing into an approaching storm should be avoided — a sudden wind shift near the ground can cause loss of control. "Seeing through to the other side" or calling it "light" does not make it safe.
