Understanding Trim

A look at what the trim wheel actually does, how to think about trim, and the proper way to use it in flight.

[@derek3778]

"Trim controls speed, power controls altitude" this was my light-bulb moment. Cant thank you enough. 👍

[@lordofthechimie]

Wow, when I was 10 years old, I was adjusting the angle of the tail section of my paper plane to make it fly more leveled. I just learned thet I was adjusting trims of my paper plane :)

[@CasuallyYobudwilson]

Yo samee

[@erinellis434]

Most helpful description of trim on youtube. Thanks so much!

[@martygraw9708]

A great way to remember which direction to move the trim wheel: forward and back to match the yoke pressure. Student Pilot here and this will stick with me.

[@badw01f23]

This changes everything. I always struggled to stay level in flight sims

[@christianh8636]

PHAK explains it in just a few short sentences, but you were able to explain it thoroughly and in like 2 minutes. Much appreciated! Thanks!

[@nakivad]

The way trim tabs work has seemed SO counterintuitive to me - I've read and watched everything I could find in hopes of better understanding how they work. You're the ONLY one that has made me understand what's going on. I now think of it this way: the control surface might fly the airplane, but the trim tab flies the control surface. THANK YOU, you just made getting through ground school easier!

[@AziWins]

such a nice way to put it!!

[@zachthegreat6836]

Thanks man I often times research things that I already think I have a general understanding of, sometimes I'm completely wrong sometimes there's nothing more to learn but with this video I found myself smack dab in the middle and I learned some things so once again great video and thank you Happy flying 🛩✈️🛫🛬

[@Nana-wu6fb]

Thank you so much man!!!! The forward/backward way of thinking about trimming is so much more intuitive! Appreciating making the videos

[@briangoss6766]

Probably the best job in explaining trim I've ever heard!

[@voiceluckan]

Thank you for the great explanation , I had quite a bit of a hard time in getting right how the trim tabs work, mostly because of how they work contrary to elevators in a way, but now I understand fully, thank you

[@Cheka__]

I'm not a pilot but this is a very interesting and informative video. 👍

[@skylab14]

Same here. This was a very well done video, easy for a layman to understand.

[@adfield8293]

Very nice for learning how trim works with speed changes! thanks Jeff,

[@niharmodak7686]

Awesome video and amazingly explained.

[@youmustbekidding7341]

The best explanation of trim I have watched.

[@YuDuTheMath]

OUTstanding explanation of trim and stabilized flight. Bravo

[@curryblackwell1769]

Best video on trim I have seen….& I have looked for a lot !

[@dickdickenson7587]

Thanks a lot Jeff!!! You explan that topic in a details which I was looking for :D I could't find this info in an ATPL books and you did it :D Big Thank you again :D

[@DavePFilms]

I'm going through ground school and this helped so much! I appreciate you!

[@lovetofly32]

Thank you!!! I watched a different video where he used a computer generated image but he had to color draw a trim tab on the stabilizer and it didn't move! Then he just focused on the trim wheel and didn't explain which way it actually moved the tab! Thank you for explaining it! I was pretty sure this was the way it worked but you confirmed it for me!

[@TheHowToTutorials1]

I have an exam of aircraft stability soon and this video helped me a lot!

[@masonhenslee5905]

Thanks man. This helped a lot. Very clear explanation and great visual.

[@lies137]

thank you sir .. very informative .. answered all my questions!

[@a.ah.3293]

Thank you sir The only Video that helped me understanding trim Thnx

[@D800Lover]

Thank you for explaining that. I almost was thinking that there was a fault with my flight simulator setup. The action is on the elevator and not directly on the air, hence the trim tab moves in a way that is not intuitionally simple.

[@lucywucyyy]

i never had a problem with the trim wheel being up to go down, i always thought of it as rotate the wheel in the direction i want to rotate the plane

[@playing44]

Thanks, very helpful information!

[@_FreeDee_]

Finally I get it! Thank you so much!!

[@michaelmike5709]

Great explanation !

[@CasuallyYobudwilson]

Very informative, been looking for a video on how to trim your aircraft, i play flight simulator games. I have a big passion and dream for future, i mostly use this for my paper plane. Stupid birds keep striking into my engine, makes it lose balance, since i haven't known what and X, and V, trim is, atleast i knew something thanks man

[@marcomizzoni8323]

Excellent video!!!!

[@mikeleput2580]

Thank you for a great lesson

[@eltonrandolph7998]

Much appreciated, Jeff!

[@BlakeBlackstone]

This is the best explanation ty.

[@AliKhan-ok5sb]

This was great, Thank you!

[@tatasisi2656]

you are awsome thanks this helped alot u got a new subscriber

[@bishopdredd5349]

This video really helped me understand trim with regards to the crash of KZbinr TNFlyGirl.

[@kinaritakashima]

i didnt understand trim before i watched the video i now understand trim thank you

[@user-ou7bc6ne8w]

solid video. I would just say that none of these surfaces are "pushing air" when the shape of the wing become more flat it reduces lift and there for lowers causing the nose to rise. when you adjust the trim in the opposite direction to cause the elevator to move down, that increases pressure below the the wing there for increasing lift, causing the nose to dive.

[@ALI53481]

Good job 👏

[@svsoleil3255]

thanks...great video...trim demystified..

[@ZimmMr]

Love it!

[@lucywucyyy]

i thought xplane got the trim tab inverted by accident, i didnt know it was supposed to be like that lol

[@erandhaa8013]

great content!

[@igclapp]

Thanks. I would comment that it's not the case that pitch always controls airspeed and power always controls altitude. Each one can affect speed or altitude ("pitch+power=performance"). It's just that in certain situations (such as high drag, high angle of attack), pitch is more effective in controlling speed than is power (we call pitch "primary" for airspeed in that situation). But when flying an ILS approach, it's easier to think of power as more effective to control speed.

[@Begheloco]

Very good, very clear and detailed. For more videos like this on KZbin \o/

[@waitdaniel]

May i ask which flying game is it?

[@Blgtn43]

Thank you.

[@montasiraminnayeem9302]

Thanks man

[@rijanparajuli1976]

Sir what about servo tab?

[@gilliandillon8757]

Bruh its like frickin cruise control

[@northyland1157]

what does this have to do with SSDs?

[@mohammadal-shehri4715]

Thank you for the informative video. I learned a lot here. I have question plz. Cessna doesn't come with Rudder trim, correct? The reason I'm asking this is that when I'm flying the same way in the video with trim adjusting, the plane keeps banking to the right. No wind is applied and gravity in the center of the plane. Any idea? Thank you again...

[@jeffschaefer7223]

Many Cessnas do not have a cockpit-adjustable rudder trim. But they will still have a rudder trim. Look for a metal tab on the back of the rudder. It is somewhat triangular. Don't touch it! This is meant to be adjusted by a mechanic on the ground. When you are experiencing your issue with bank, look at the ball. If it is not centered, apply rudder until it is. If the plane continues to bank then you have an aileron trim issue. Many cessnas do not have aileron trim either. If this is happening in the simulator you can often add a button for aileron trim even if the real plane doesn't have it. You might also check if your fuel is balanced and your joystick calibration and null zone. I hope this helps.

[@azdurjoy]

can you tell which simulate app you used here? because I want to use it as a pilot student. Thank you so much to keep us updating.

[@jeffschaefer7223]

X-Plane 11

[@azdurjoy]

Jeff Schaefer thank you so much! And give us more and more take off and landing related videos. And gives us small but very helpful tricks videos, brother. Again thank you so much! Today I about Trim. Video was so good and informative.

[@praneethvarma9189]

That was a perfect visualization, Where are you doing all these? Is that a real flight simulator

[@murrayhelmer8941]

@coviron21. Hope this makes it clear how it works. If your elevator was jammed using the trim wouldn’t help you control the plane.

[@igclapp]

Well, in the case of a jammed elevator the trim tab might have a slight effect acting as a small elevator. But it would work in reverse. Moving the trim wheel foward would cause the nose to rise.

[@jurel6982]

Why does the trim move by itself?

[@manuciucanu5609]

Where i can find that simulation, it's an app?

[@michelebianchi7861]

what simulator is that?

[@lucywucyyy]

maybe itd be easier to think of the up and down on the wheel as up in spead or down in speed, or maybe up on the tail or down on the tail

[@1UTUBEUSERNAME]

Now I understand. I got this question wrong on the exam because it is not intuitive at all especially to a boater. Now I see your video and it makes sense. Raising the trim tab pushes the elevator down causing the nose to down. The trim tab does not move the plane, it moves the elevator.

[@edwardguillen6610]

Why the trim tab is only on the left side of the horizontal stabilizer (Cessna 172)?

[@jj12345og]

There is another on the other rear stabilizer on the other side of the vertical stabilizer

[@igclapp]

It's only on one side for simplicity. Putting another one on the other side is not needed and would add cost, weight, and might potentially be less reliable because there is more to go wrong.

[@ericbonnes7429]

What software do you use for your videos?

[@jeffschaefer7223]

Filmora scrn

[@dtsh4451]

The description until 0:58 is confusing: the yoke is pushed forward , elevator is down, the elevator surface air pressure reduces. The air from the bottom of the elevator pushes the tail up and the nose down? The video talks about the air above the elevator pushes the air down?

[@jj12345og]

Yeah, the elevator has the air follow it basically, that is also how wings work (along with pressure too)

[@johannesdolch]

It really fascinates me when people play flight sims and opt for a Cessna (or any other civilian aircraft, really). I mean it's a simulator. You could be flying an F-35B, F/A-18C, F-16C or even just a B-1B or B-2. (Then again I mostly play shooters, so maybe i am not a pilot at heart and just love things that blow stuff up, lol)

[@jj12345og]

They are rather simple planes compared to jet fighters and military aircraft

[@samoo8933]

Guys may I know this flight simulator app name please ?

[@Manuqtix.Manuqtix]

Name of flight simulator?

[@turkibinsalman1717]

Did you know?

[@samsam-tt3bk]

Cruise control for altitude

[@smark1180]

False

[@funnyfunkall]

your video are good but to make it best you need to make video short and sweet ok

[@lucywucyyy]

an elevator for your elevator

[@arkkon4715]

I don't think you used the best verbiage in this video. The air is not being pushed, it is being deflected. This can make your communication a bit confusing for students who are trying to understand the concepts of the secondary flight controls. otherwise, nice job

[@mylifentimes]

Thank you.
