ACS element text (the applicant demonstrates understanding of)

Effect of environmental elements on airplane performance related to spins (e.g., turbulence, microbursts, and high-density altitude).

Bottom line

Severe turbulence aloft, although not common, can result in loss of control and may lead to aircraft structural failure. Maintain awareness of conditions that can lead to various types of turbulence, such as clear air turbulence, mountain waves, wind shear, and thunderstorms or microbursts.
