Sorry for those pops on the mic at some points. That's what I could do with the basic equipment I have where I am now :(
If you have more to add about Wake Turbulence, please leave a comment so we can take note of it :)

Well done Samuel. Glad you and passengers are safe.

Thanks for the analysis Victor. Most serious wake encounters occur when flying in the same direction (like that DR400) or exactly reciprocal to the vortices (like that Challenger), and that's when you get the roll that flips the plane over. Samuel crossed the wake at JFK perpendicular to the vortices, so he got a couple of very quick up & down severe jolts rather than a rolling motion. Either way, it's enough to shake loose a battery or even knock the pilot out when they hit their head on the ceiling.

Thank you for this explanation in general, and also several avoidance options. It seems particularly important what a pilot should be thinking about, and what to do when he hears the wake turbulence caution.

First of all, awesome work by the PIC and ATC and thanks Victor, I learn a lot from these videos. Although it was a serious incident, following proper procedures and having situational awareness made this a perfect emergency landing.

I read a comment stating if it would have been better if the pilot stayed below Bravo at 500ft. I kind of agree because it seems like the PIC hit the wake turbulence after or during the climb and we are always taught that if you encounter (or have a chance of encountering) turbulence, the best thing to do is to maintain a steady and level flight. But another way of thinking is that I would rather encounter wake turbulence at 1500ft as compared to 500ft; that extra altitude might have given enough time for an emergency landing at JFK.

Either way, for learning pilots such as me, (according to me) it is very important to establish the fact that ATC can only give us caution warnings and PIC has the final say in order to make sure that the aircraft and the personnel are safe. Might be a better idea to stay in a holding pattern or delay the take-off/landing if there is any chance of encountering wake turbulence especially for light category aircraft.

Just a point of clarification...Wake turbulence is synonymous with 'wing tip vortices'. It doesn't include jet blast or general air disruption as the aircraft 'moves through the air' as you put it. The distinction is important because jet blast and general air disruption is generally short-lived and doesn't linger for nearly as long wingtip vortices.

Student pilot here. Thank you Samuel and VAS. Without this real story plus the videos I don’t know if I would really get how scary WT is.

[IorekByrnison]

Great analysis!!! Very informative... Keep up the great job...

[peterfrenzel]

excellent video, I was flying a lear some years ago up in the mid 30s and the controller advised that a tripple 7 was crossing my path 25 miles ahead from left to right 2000 feet above, I saw him crossing so far ahead BUT when I got there, there was a loud bang as if someone took a large sledge hammer to the roof of the lear and a shutter and vibration, it was a big scare for me and the pax thought that we hit another airplane, all was well and no damage but what a wake up call to what wake turb can do.

If the piper did a left 360 (2 minute standard rate turn) before the 777 landed, Im sure the wake turbulence would’ve been gone and could’ve proceeded on safely.

[Boodieman]

I have to say well done ATC for the job they did both with two warnings and then trying to get the airplane on the ground and the emergency trucks rolling.

[Flyboyed]

I fly a PA28 a lot and I just learnt something new.

[apfelsnutz]

The danger is from the TIP VORTICIES off the wings. The turbulence cork screws and slowly drops of the end of the wings much like a tornado moving horizontically and can last minutes...

[KienTran]

Should the ATC have cleared the Piper to 1400 crossing the path of incoming large aircraft? Would he have been better off staying at 400?

Caution, volume differences may cause headaches for headphone users.

A CRJ 200 lost an engine on takeoff yesterday out of Denver. You should do a video of that!

[patim]

Just wondering, does a battery not need to be fixed in place in a plane ?

[lancomedic]

Fantastic followup to your other video. These two videos should be incorporated into flight training. Actually you should contact the AOPA to see if they want to put it into their series of real pilot stories. Your radar and ATC communications really tell the story.

[BlackBuzzzard]

Was the battery firmly and correctly fixed in place before turbulence? Battery should not be moving with rough turbulence.

[roflchopter]

10:55 does the turbulence really descend due to gravity? Is it not the the same density as the surrounding air?
