Flying In Ground Effect (Private Pilot Ground Lesson 14)

[@flyguy1637]

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!

[@FreePilotTraining]

Thank you so much! I’m so glad you’ve found these helpful!

[@dmacnet]

I love how you tied all of those concepts together.

[@FreePilotTraining]

Thanks!

[@shawn5141]

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

[@FreePilotTraining]

Thanks Shawn! I appreciate that

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

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

[@FreePilotTraining]

No problem! Thanks for watching

[@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.

[@FreePilotTraining]

Awesome! Glad I could help

[@Stumpchunkman226]

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!

[@FreePilotTraining]

Thanks! I appreciate that!

[@uprzejmypiesio6875]

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!

[@FreePilotTraining]

Awesome! Thank you so much for this comment! The videos only get better from here!

[@dillonleverette307]

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

[@FreePilotTraining]

Thanks! I appreciate that

[@iliegotca1049]

Thank you. You the best!

[@FreePilotTraining]

Thanks!

[@timmy2482]

Thank you for doing these! 🛩

[@FreePilotTraining]

No problem!

[@johnf6545]

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

[@FreePilotTraining]

Thank you! Looking forward to seeing you around!

[@Cosme422]

Please, please, no music in future videos please.

[@FreePilotTraining]

Thanks for the feedback. I don’t use much music on my newer videos

[@Nz-mq1er]

just focus on

[@jakew9887]

Great presentation. Thanks.

[@FreePilotTraining]

You’re welcome!

[@arwood111]

Thank you!

[@hahadoo1059]

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

[@FreePilotTraining]

Thanks!

[@etieldagan3306]

Great videos. God bless you!❤

[@FreePilotTraining]

Thanks!

[@memphisbaker237]

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

[@FreePilotTraining]

Awesome! Thanks for joining the channel!

[@pfsantos007]

Great videos.

[@FreePilotTraining]

Thanks!

[@victorcovarrubias3606]

Very informative video thank you.

[@FreePilotTraining]

You’re welcome!

[@OldCarsAreFun]

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

[@FreePilotTraining]

It very well could be. That’s cool. I’d fly RC planes but my wife only lets me have a couple expensive hobbies lol

[@9LimaAlpha7]

could you explain what is a soft field takeoff??

[@FreePilotTraining]

A takeoff from a grass field

[@9LimaAlpha7]

@@FreePilotTraining can a general aviation aircraft - such as a cessna - takeoff from it? considering the height of the grass, would that be a wise thing to do?!

[@ZenithE8]

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 .......

[@FreePilotTraining]

If you get asked about it, I’d just call it a layer of air between the ground and wing that gets in the way and keeps the airplane airborne a little longer

[@ZenithE8]

@@FreePilotTraining Thank you!

[@underSTATEDexcellence]

You really need to watch out for Helicopter wake.

You’re welcome! Thank you for the Super Thanks!

[@t-rex_1713]

How exactly do wingtip vortices cause induced drag?

[@t-rex_1713]

P.S. I'm studying for my private right now and your videos are incredibly helpful

[@FreePilotTraining]

Thanks!

[@FreePilotTraining]

They disrupt the air flow over the top of the wings

[@The_real_Dr_mysterious]

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

[@FreePilotTraining]

A lot. Lol. This is a good read. www.skybrary.aero/articles/mach-tuck

[@phoonjzc]

understood most

[@myyouth6864]

What does “airborne” mean?

[@FreePilotTraining]

You are no longer touching the ground

[@FloridaRazed]

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

[@FloridaRazed]

I love the content though I just find myself pausing the video alot 😅. I'm taking my discovery flight today and waiting on VRE to process so I can start this journey

[@FreePilotTraining]

Yeah, sorry. I have plans to remake these. I’ve got 4 videos left in the PPL series and I’ll slowly start remaking these and working on instrument videos

[@FloridaRazed]

@FreePilotTraining lol so I know nothing yet about flying and these are very helpful at least to have somewhat of a head start. Getting kinda nervous about reading airspaces and not getting into trouble😅

[@FreePilotTraining]

@@FloridaRazed you’ll be fine. It just takes a little bit of studying and you’ll get it

[@iliegotca1049]

@@FreePilotTraining it is ok. I make skreen shotts. Ahahahaha
