This information is for training and informational purposes only. Wake turbulence is generated whenever an airplane is developing lift. The heavier and slower the airplane, the greater the wake turbulence. Your key to avoiding wake turbulence is to always fly through undisturbed air. A Bombardier CL604 Challenger suffered catastrophic damage at FL 340 from the wake of an Airbus A380 flying at FL 350. The report is very sobering.
