Risk-Adaptable Access Control (RAdAC) This paper considers the impediments of traditional access control approaches to sharing of. information. It describes a concept for an access control model that emulates real world decision-. making, considering operational need and security risk as part of each access control decision, and.
Turbulence can occur in the lowest part of the troposphere during the daytime when heating of the sun causes convective mixing of the air. Once the airplane rises above this turbulent boundary layer, the air becomes smoother. But other processes can also cause these up- and down-drafts.
Pilots are taught to slow down when they encounter turbulence. âWhat you donât want to do is fight the turbulence,â Yurman said. âIf turbulence is causing you to go up, you donât want to push down hard on the controls, you want to try to slow down and ride it out to the other side.
