- Ever wondered if a plane's cleanliness affects its speed? 🤔✈️ Join me and my Piper Comanche 250 on an aerial adventure as I put three contenders to the test: a spotless plane, a dirty bird, and a plane that's clean on one side and not so much on the other. 🧼🛩️💨 Watch as we compare how they soar through the skies - will the clean plane glide smoother, or does dirt add an aerodynamic edge? Or perhaps, it's the two-faced plane that takes the lead with its split personality. Buckle up for a flight of fancy filled with laughs, science (sort of), and a definitive answer to the age-old question: Which flies faster, a clean or dirty plane? 🚀🤣 Don't forget to like, share, and subscribe for more quirky experiments and high-flying fun!

For a proper science experiment, the results need to be repeatable. When are you available to clean my airplane and repeat the test?
Yeah. He should clean all our planes on the regular, just so we can provide continuous scientific data.
"parasite drag"! I spilled my coffee on myself, absolute gold
It has been a well-known fact clean airplanes fly much faster then dirty airplanes... I learned that from my father at age of 12...He gave me that wisdom just before he informed me it was my job to wash and wax the plane
Finally, someone explained parasite drag in a way I can understand.
If you clean just one side you won’t need right rudder on take off. Good way to get rid of the left turning tendencies
P-factor as in polish factor.
Sold science.
Men lie women lie numbers don’t.
But then the passenger is looking at the dirty side.
You’re telling me all the bugs along the leading edge aren’t “poor man’s vortex generators”? Somebody’s gonna have to pay for making me live that lie.
Always needed an answer to that existential question every pilot has! 😂😂😂😂
lol 😂 love the “low fuel” burn… haha
"...110 knots cos the plane is so dirty" 🤣.. bro that bird couldn't even have 110 knots printed on the speed dial without breaking up.. 🤣🤣🤣
As a professional aircraft detailer, it is real science that certain sealents and waxes will make your aircraft go up to 6 knots faster.
Great video Bryan. I have one more question for you to answer. If you also clean all the heavy lead deposits off the belly, will it increase your useful load? It would have to be good for 3 or 4 more hours of fuel. I passed my PPL checkride a few days ago. I want to thank you for being inspirational during that journey. Keep up the excellent work. Safe skies my friend 🇺🇸🛩️
Can you do a follow up video? What happens if your plane flies backwards? "All for science"
It'll be interesting to see that - and the "Gas-o-Meter" putting fuel back into the tanks!
Thank you Sciiiientist Instructor BrYan! I have the same inability to differentiate parody from reality as the FAA, so I will totally work from my new understanding of "parasite drag" in all future FAA tests/checkrides!
Instead of cleaning off the parasites why not prevent them? Frontline Flea and Tick Spinner Collar. Or the chews you can put right in the fuel tank. Sciiience.
Also Tiki Torches for the mosquitoes.
You are a jeenyus ! Should be Bryan’s R&D direkter
ThIS!!!!!!
I like it when bugs make a home in my Static Port. The airspeed becomes much more impressive.
I still recall one of your previous lectures.... As you can wash the parasites of, you also wash these invisible sticky clouds of the wings too. That is the real magic! May I advise you to wear a white coat? All scientists wear white coats and you'd be easier to find when flying into a black hole with those hyper speeds!!!
Thanks for sharing the airspeed indicator. It helped me understand why I couldn't make the upwind leg at -13C.😉
Pretty conclusive scientific proof there! but you missed the final test - if you give the plane a good wipe with some t-cut or similar to get all those scratches out & fully restore laminar flow, could you get it back to being supersonic, or alternatively cut your fuel burn to near zero?! also throw all those old triplicate forms out, for goodness sake, all that extra drag there too.

Going to those extremes for the sake of a bad pun was award worthy, bravo :D
You need to put the wind sock back on the wing. It’s very risky flying not knowing the direction of the wind at all times.
Wow. Several points (1) Absolutely stellar still-frame work with the speed-o-meter. That's hard to pull off. (B) Around 6:30, I noticed your Flight Aware track is using a Canard Icon and I think there's an update for that. Did the same thing to my Cessna Quad-Pacer. Finally, last point (Unicorn) this should be considered by students the definitive video on the influence of drag. To avoid any confusion, this should be the only drag influence allowed in schools. Safety first. GREAT JOB!
The speed-o-meter photos took a lot of skill. 1. I have good cameras, 2. You build up skill over time. I wish I could say those shots were easy to get but the truth is, I have a gift.
Thank you for explaining parasite drag…been looking for a good way to explain it on my upcoming checkride
missed a trick there Bry. "scYence"
12 seconds too short 😂
Great video BrYan!
If I had a dollar for every time my wife said that, I could afford a mechanic
HAHAH!!!!!@@circuitmonkey6653
That’s what she said……
Yep, I, too, was one of those airport kids who washed and waxed airplanes in exchange for flying lessons back in the early 1970s. And I can tell you unequivicably that the difference in flying a dirty airplane vs a clean and waxed one is akin to the difference in drawing a sharp knife through a bowl of creamed cheese vs through a bowl of water. However, bugs vs dirt... I'm not sure which one was worse for drag, but the wax sure improved the speed and feel of the machine.
Mythbusters actually did the dirty vs. clean fuel efficiency experiment with a car. But I don’t know whether they’re scientists.
Had me laughing from the start! This is another real banger!
Please no more fakey-shakey camera though, it's the only time I got motion sick from a video. Oh, and thank you for confirming that the black rectangle hanging from the ceiling was indeed a cellphone 👍
That’s my favorite course you teach to date!!!
I needed a laugh. 👍
Hahaha "Parisite Drag" ......Brilliant!
So... If the windshield is dirty enough, can you log it as IMC? Asking for a friend with a Y in his name....
Love it!
Bonus points if you add turtlewax (MIL-WAX-420) or just rub a fine coat of oil all over the airframe. It gets into the metal grains and smooths out any imperfections. I’ve done this in my C172RG and went mach .72 (hence the 172 nomenclature).
“I’ve got a terrible fuel burn” sounds like you should put more of it in the tanks and less on your skin!
You did the GA community a great service. I actually already knew all this though. My co-owners and I clean the bugs off our Cheetah after every flight (bylaws). I take it a step further and only fly on hot days so I can thermal up with 1/8 engine power and when I get high enough, I just fly down hill at idle so I average a -1.8 gph. When I get back to the airport, we are required (bylaws) to refuel the plane to standard fuel level but I always get to put fuel back into the pump and get some money back. That's why I don't go to the fuel pump and KXBP. KDTO pays way better!
Looking forward to the SRC (Sarcasm Recognition Course) next week. Sent my money in cash as requested next day air. Don't know why its 100 miles out in the desert but, ok.
Also ... Just read in a scientific journal that if you leave the wings on the bugs, it actually helps lift. Try a test where you only clean off the really damaged bugs!
Tell us more about the Wind Deflector 2000 Extreme. Is it better than the Pro model?
Hey Bryan, good to see a new spoof video. Better dust off your NTX FSDO frequent flyer punch card. Thanks again for the correspondence wrt preflight data. Keep making GA fun.
Hey Bryan, you missed important point that if you clean the prop the plane starts producing the fuel and you have to land not to empty the bladder! Coincidently, FAA is introducing new section in ACS to calculate how often you need to stop to perform the procedure!
Waiting for the "Just Plane Shiny" patented cleaning product range to appear on the shelves.
You forgot one of the downsides to removing the parasites. I've always removed every bug gut from the center of the leading edge down towards the ground. The remaining ones on the top act like vortex generators! Unbelievable but oh so true!!! I can actually get it so slow and trimmed just a few inches over the runway then climb out and run to the restroom in the FBO and get back to climb aboard before it reaches the other end of the runway, then retrim for a climb out! All without the aircraft ever landing. They do cost me a couple knots off the top end. Thanks for explaining the amazing principles of science behind it all.
I think you get the best performance flying straight down with clean wings.
I need to know what wax you’re using. I need all the help I can get. My ground speed to Airventure last year in my C170 was 77 knots.
Probably going to need a coat of wax too then
Hey you just taught me something very very important- even on top of all that complicated aviation related fuel-o-meter data. I have a computer science degree as well. So, I too am a SCIENTIST…I feel smarter already… well aaaalriiiight. 😂
It’s such a shame even when my plane is clean my slowtation doesn’t go any faster. You know how I know? The bugs still get cleaned from the trailing edge.
Wow, you need to teach your students how to read their POH! Just open it up and you will see that it clearly has different numbers for a clean configuration!
HAHA!!!!!
The performance difference is significant enough that competition sailplanes have "Wing Wipers" to clean the bugs off the leading edge during flight.
This is not a joke.

Wild!
Who was your cameraman in the hangar part? You know, the one that was exposed to your Covid? (Science…) well looks like you maintained social distance.
I just cleaned my plane and the fuel-o-meter even turned negative for about a minute during cruise!
Then a bug hit the leading edge and it went back to positive instantly.
I know a guy that cleaned his Cessna 172 and then sprayed cooking spray all over the wings. He can now hit mach 3 in a dive. Absolute truth! 😁🤪
I’m surprised I don’t see mention of the yesterday’s landing in Vilnus: ruclips.net/video/J26j-dglHu0/видео.htmlsi=aVlfizLHJ4A4_ej-
I first thought this was a reaction video to that incident :-)
If you wax those wings, you can go Plaid. I’ve done it.
But what if the parasites were butterflies? Then would it go slower, or faster? And would the plane always stay upright too?
BrYan,
Using the scientific method to deduce a hypothesis, can we suggest that cleaning the prop would cause the engine to over-rev and therefore not be done?
I want a copy of the 337 for that phone charging scheme
Weight is also a factor in fuel burn. Try taking 10 lbs of air from each tire. You will go faster and have 30 lbs more useful load. It’s sciiience man.
Does cleaning the airplane always involve installing the fuel meter to a different spot? Asking for a friend.
The real question we need answered is, "Does hail damage make an airplane fly faster?"
I mean, a golf ball goes faster with the dimples! 😉
A Sciiientist with three I's, that's all you need to know about Bryans crudentials
You’ve blended me with sciiense!
OK, but did you control for the size of the bugs? 😉
Good to finally have this conundrum of the ages solved; due to your rigorous scientific efforts we now know the true extent parasite drag has on our flight performance! I'll no longer be "bugged" by this question...
Bryan, again you are a NUT ! A GOOD NUT. Seriously, your Comanche 250, with it's Laminar Flow wings, DOES actually fly faster when it is Clean and Waxed! You could see, a 7 to 10 Mile an Hour increase in indicated airspeed when it is CLEAN ! It been Proven.
You didn't mention cash drag. Does a clean leading edge affect that?
TX mosquitoes are so big that they often lead to bug induced stalls. 😉
Try Johnny’s Prop Wash to clean your plane. (yes, it’s an actual product). Your plane will be so slick, the FAA can’t touch you.
Flying sailplanes, bugs are a major issue.....lookup bug wipers....bugs can effect performance by 20%. It's tough though....polishing the bottom of the wings...I bet yours took ages.....
If you remove enough drag components, can you cumulatively attain a negative fuel burn? 😉
I know what's wrong......"It ain't got no gas in it"!
I'm 'blinded by science!'
Surprised that YT doesn't demonetize this episode for its 'insectual' content.
"Parasite drag"...Good thing you don't have bed bugs and leeches; then you'd need a good fumigant and salt to clean your plane before flight...not to mention the adverse effects on the "Fuel-O-Meter (TM)" if you get tapeworms!
Stop it your killing me 😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂
Did you have trouble keeping a straight face with the Parasite Drag line?! 😂
To be honest how it works is if I write something down I tend to laugh about it when I think about it. That particular line I had wrote down a couple days before so it was planned. There are a lot of times when I'm just being spontaneous and it takes every muscle in my face not to bust into a smile and I fight hard not to screw those up cuz usually when it's accidental and spontaneous that's when it's the best delivery
😄😄😄
Just as golf balls are dimpled to make them fly farther, so should airplanes. A ball peen hammer and an afternoon is all you need to get another 40 knots out of that thing.
It's "scYanstis" with a Y. You schould know this. Sauce: I'm a Geyallogist. Rocks for Jocks
You missed a joke about the bug speed, er speed bug
Always suspected this but now have seen it proven. Problem is I’m lazy plus we need to keep the 100LL fuel folks in business so I’ll just have to stick with the high fuel burn to do my part.
I flew over a "PAIR O' SITES" just last week and went faster😅!
Hey there! Washing airplane is routine procedure. No any science just do what you must do.
Your ASI problems could be easily solved if you upgraded the Comanche panel with 5 Flight.
It's this sponsored by simple green?
You’re every bit as much a scientist as Bill NYE the engineer guy is B.
😂😂😂😂
I don't know how fast clean planes or dirty planes are but I do know how fast dirty girls are.
Insects on the wing cause parasite drag, Bryan, but you can counteract this and go much faster by fitting the ASI with one or more speed bugs.
Apparently you are not aware of another instruement to calculate in real time. Bugonometer Transducer
Does that particular student pay you with gift cards?
Almost as legit as Trevor Jacob ... almost. He is still the authortiy on everything aviation, of course.
Bryan, my wife is not a pilot but she is a blonde and she says you didn't take a picture of your ASI and that you drew it by hand. Now who's right you or my wife?
Like you said, she's not a pilot and I am therefore by default, I have to be right
Still a picture…….
Little known fact (cause I’m just now stating it), but all of those smashed bug wings on the leading edge act like little vortex generators and will lower your stall speed. Poor man’s STOL Kit.
