The Truth About Airplane Flaps

- Let's talk about airplane flaps - you know - those big rectangles that go up and down on the wings. Do they matter? They sure do. Flaps develop more lift and lower stall speeds. They can help when descending, landing, and taking off. Flaps can even prevent a fatal disaster. But there are multiple variables involved when it comes to using them. The kind of airplane, weather conditions, runway length, weight, altitude, density altitude, and terrain are all factors at play. Enjoy this short explanation on the use of airplane flaps.

I'm a Helicopter Mechanic and I live seeing videos on Aviation topics!! You have flaps, ailerons, elevators, stabilators, etc.. LOL.. Keep up the GREAT work good sir!! Much respect and support from Yuma, AZ. 👍👍 (The big airliners also use Thrust Reverser's to aid in slowing down)
Nice video. One trick for using flaps to shorten takeoff roll while minimizing drag is to start the roll with no flaps then add a notch or two as you approach rotation speed. The plane may balloon a bit and the trim setting will most likely be off slightly, but it works. The pilot just needs to be ready for the change in dynamics.
I always include no flap landings as part of my primary training task list. It’s not in the ACS but certainly should be covered.
That’s interesting. Thanks for adding to this discussion!
Thanks for a great explanation on the use of flaps, I found it really helpful as just started to get to this point in my PPL training on the P38.
Awesome and so interesting! Thanks for nice sharing! Have a great day
Thank you! You too!
I am very interested in getting my PPL. This video was helpful. Would love more!
Hey thanks for the feedback! That means a lot. I'll keep them coming.
The PA28-180 I’m training in, I use 25 degrees flaps to takeoff. It helps the airplane lift off at a slower smoother speed. When I don’t use flaps I need a higher airspeed to liftoff and the nose wheel shimmy’s really bad. Thx for the great video!
I’ve heard that about other planes as well! So much easier on the gear and tires to lift off earlier.
Amazing thank you
Good video. I was actually thinking that for LSA size planes or even SR22 that with a light construction it might be better to not have flaps because of the reduced complexity leading to ease of construction and lower price and bigger market. With certain gear height you can flare the plane. If we are talking a quarter of a second more on the brakes if even that, is that not worth it if you can lower the plane weight and cut the cost by maybe 30%. A huge problem in aviation is cost and the plane producers are eternal whiners about market size. Our WW1 plane has to cost 400k or we can't survive. I'm talking about the awful atrocious carbon cub.
A Tesla Model 3 starts at 40k$. That's a pretty sophisticated vehicle. A carbon cub fabric over metal is over 400k. GA is a disgrace.
Flaps don't develop lift, wings do! And they don't add lift. Unless you're using flaps that increase the wing area. What flaps do do is change the cord line of the wing. That's why you can Land at lower speeds with the flaps down. The jet could land at the lower speeds without flaps. but it would have to increase the angle of attack to such a point that the tail would hit the ground before the wheels would. But on some big jets the flaps actually increase the wing area. So deploying the flaps would increase lift. Again flaps don't add lift (unless the add wing area) they just change the angle of attack the airplane needs to fly to create the same lift.
Come on dive flaps are air brakes. Not landing flaps. Have nothing to do with landing. That airplane comes with split flaps. When using landing flaps only the bottom half deploys. When they use it as dive flaps (it's really an air brake). The top part opens along with the bottom. Not meant to change the cord line in any way. Just to create drag. So flaps they are not, at least not when used as air brakes.
did you re-cut this one? I went live a few days ago but has popped back up today... (that's only an FYI)
Yes. I had to fix a few things. But it's all good now.
Wow i never knew this
Yes
I am new to aviation. I dont understand how if flaps increase drag the can effectively increase lift on takeoff. Wouldnt the drag at that stag hinder lift? Thank you.
It seems they would but no. Flaps enable the airplane to fly at a slower speed. Therefore, the wheels can leave the ground at a slower speed.
@@BradySkye Thank you.
@@BradySkye Its sooo complicated. So mant things to calculate. At this stage it boggles my mind thinking I could ever get all of it to muscle memory. Thanks.
@@taissawoods3359 like anything you won’t know everything overnight. It all comes little by little and adds up.
Nice video
Thanks! There was a lot more to say here about flaps. I was trying to keep it short. Fun video to dive into though.
@@BradySkye
I'm looking forward to seeing more!
Brady... are you guys all ok with the hurricane going thru??? Please reply as soon as you get power back on. Thanks... worried about you!
Power is back as of 2 hours ago! Releasing a video of what I was able to capture from the storm tomorrow.
@@BradySkye soooooo glad you're ok dude..... WHEW! be safe now too.
Are u on instagram?

The subject of flaps is fascinating because it varies so much from airplane to airplane. Some airplanes I have heard won't launch off the ground without the flaps and some I have heard won't launch if you have too much flap. If a pilot blows is approach and has to make another pass they generally say to take the flaps off and then put the flaps back on. I've always been curious about this.
Well typically you don’t want to have flaps on when already in the air and climbing. So for a “go around” you would retract the flaps once you decide to go around and gain altitude, then extended them again once you’re on your downwind passing the numbers getting ready to attempt to land again.
@@BradySkye I always thought that was kind of foolish myself. If you're going around and landing right away why add another thing to do and undo before you make your landing pass? I looked into this and some airplanes won't climb out with full flaps, at all no matter the speed no matter how much throttle if you've got those flaps on they are slowing you down to land. Is this true?
@@markmcgoveran6811 Yeah it really just depends on the airplane. You can climb at 10 degrees of flaps but full flaps is way too much drag. In a small plane on a big runway you don't want flaps when climbing.
@@BradySkye yeah that's the difficulty. You are thinking about a climb out to power up and head somewhere. In the landing aborted and go around situation I am in love with the low stall speed the flaps give you. There's been a lot of cases of airplanes touch in abort the landing coming around for the next landing at attempt and stall and hit the ground hard. I've always wondered if not using the flaps during this low speed low altitude come around tight corners in a pattern causes this stall problem?
thanks, i wanted to understand flaps better ... because i'm considering adding flaps on my model: czcams.com/video/lvNR_mA-zYE/video.html
