Question

Quizplus · Accepted Answer

Clear-air turbulence poses a serious hazard to aircraft as it cannot be detected by radar or visual cues and can result in severe turbulence that can cause injury to passengers and crew, as well as damage to the aircraft. Molecular viscosity and laminar flow are factors that affect aerodynamics but do not pose a direct hazard to aircraft. Longwaves in the westerlies refers to atmospheric patterns and is not a hazard to aircraft.
