What is the primary risk to aircraft from thunderstorm-associated turbulence?

The primary risk to aircraft from thunderstorm-associated turbulence is the potential for loss of control. This is because thunderstorms can create extremely unpredictable and severe turbulence, which can exceed the aircraft's design limits and lead to challenges for the flight crew in maintaining stable flight.

During turbulence associated with thunderstorms, sudden changes in wind speed and direction can occur, causing large and abrupt movements of the aircraft. Pilots may find it difficult to keep the aircraft on course or manage its altitude. If the turbulence is severe enough, it might lead to situations where the flight crew struggles to maintain control, especially if they are caught in downdrafts or updrafts that can be significantly stronger than normal conditions.

While structural wear, physical injuries to passengers, and decreased fuel efficiency can occur due to turbulence, the immediate and most critical concern during severe thunderstorm turbulence is the crew's ability to maintain control of the aircraft. This aspect highlights the importance of proper training and preparedness for pilots and dispatchers when anticipating and responding to turbulent weather conditions.
