Flying In Ground Effect (Private Pilot Ground Lesson 14)

Flying in ground effect! This video explains ground effect and wingtip vortices. This is private Pilot ground lesson 14 in our free private Pilot ground course. This video explains ground effect by first explaining wingtip vortices and what causes them. We discuss wingtip vortices and how they are related to angle of attack and airspeed. We also explain how they cause wake turbulence and how we should avoid wake turbulence as pilots. We then dive into ground effect and how it is caused by wingtip vortices being disrupted as we get close to the ground. This information will help you study for the private Pilot written exam and the oral exam for your check ride. This training is intended to follow the aeronautical knowledge areas in Part 61.105 section b for single engine aircraft.

I love how you tied all of those concepts together.

You have the best aviation instruction videos that I have run across so far. I am a retired Airline pilot and am presently renewing my expired Class 2 rating after 43 years and these videos are excellent in reviewing the curriculum for my renewal. Thank you! I use this in conjunction with my study material!

This series is awesome. Thank you so much from those of us that are in the beginning process.

[dillonleverette]

Per usual you put out digestible and factually sound info. Thank you sir!

[jspardine]

I’m preparing for CFI-A and I had only understood ground effect as far as a cushion of air and I thought it was due to increased air density. Your video really cleared it up. I’m not 100% until I review more, but this was very helpful.

[uprzejmypiesio]

Damn, i am after the ATPL Principles of Flight theory course and i had problems with understanding things like ground effect or just a downwash. It changed with these lessons, i will keep watching the series!

[johnf]

Excellent full explanation for noobs like myself, subbed, looking fwd to the rest of your videos!

[Stumpchunkman]

I really like these videos. I always check out your series when I’m looking for a particular piece of information. I also appreciate that you accept and consider constructive criticism. Thanks for everything!

Commenting for the channel’s #’s.
Great video!

[hahadoo]

I started watching your vidoes, it is great for starter like me who doesn’t know where to start!! ai love it. 🎉🎉

[memphisbaker]

Hey friend, just found your channel and am going through a 141 course, man do you make it easy!!

[Cosme]

Please, please, no music in future videos please.

Is that the hobbyzone mini super cub in the thumbnail? Thats awesome, that little 3 channel rc plane was the first thing i got to fly

0:18 wingtip vortices
-byproduct of lift

0:33 lateral flow
-the high pressure air below the wing rushes out and then up to meet low pressure on the wing and the downwash from the propeller on top of the ing meets that high pressure and pushes them back down which cause it spiral
-this causes induced drag
-higher angle of attack means bigger vortices and more drag

1:25 at lower airspeeds when need a higher angle of attack to keep lift and weight equal but at higher speeds we don’t need a higher angle of attack so we have less induced drag

2:12 most dangerous encounters are planes that are heavy(higher aoa), clean(no flaps) and slow


2:55 don’t follow aircraft within 1, 000 feet

3:05 during take off and landing wait 3 minutes for vortices to dissipate. The movement is 2-3 knots and they move laterally. A crosswind can make them stay in the runway longer

4:09 ground effect
-reduces size of wingtip vortices which give us more lift and less induced drag and less thrust
-during takeoff you can become airborne before recommended airspeed
-you’ll leave ground effect and you’ll need a high aoa, youlll have more drag and reduced stability and the pressure change will make you think you’re flying faster than you are

6:20 ground effect affects low wing airplanes more

[LimaAlpha]

could you explain what is a soft field takeoff??

[ZenithE]

This is the type of thing that I worry about being tested on.. I can somewhat grasp it but to explain it back to someone else

[t-rex_]

How exactly do wingtip vortices cause induced drag?

[The_real_Dr_mysterious]

What happens to the wind when you break the speed of sound

[underSTATEDexcellence]

You really need to watch out for Helicopter wake.

I know you did these 2 years ago but your animations are too fast that you can't process the animation after you described the topic to compare audio with the graphic
