1. These jets have been demonstrating wingtip vortices and the hazards associated with encountering them.

2. These can roll you on your back and ruin your whole day. 3. How does it work? The high pressure molecules below the wing work their way around the wingtip to the low pressure molecule. By that time, the low pressure molecules are gone! 4. Wingtip vortices are the greatest when the pressure differential at the wingtips is the greatest which is when the AOA at the wingtip is the greatest. HEAVY CLEAN SLOW 5. Crosswind can drift vortices over adjacent approach and runway 6. BeginTO after large aircraft landing point Climb out above & upwind of large aircraft flight path Land after large aircraft touchdown point Land before large aircraft takeoff point Light quartering tailwind can hold over runway 7. This goes for consecutively smaller aircraft not just Cessna and Piper type aircraft. 8. Youre on a X-C and big jet crosses in front of you about a mile ahead. The FAA is going to ask you What should you do to avoid wake turbulence? The answer is to make sure you are slightly above the jets flight path. 9. So lets assume that instead of flying near a big iron airplane, youre flying in the vicinity of a big iron helicopter like this. Well, do you have to worry about wake turbulence behind a helicopter? 10. Yes, and as matter of fact, in forward flight it trails behind just like it does with an airplane. 11.
