What is that spinning thing?

In this episode I will discuss an item in the cockpit that I continue to get a lot of questions about.
What is that spinning thing next to the thrust-levers?
stay tuned to find out and feel free to download my "Mentour Aviation" app using the links below, I have just added a documentary that will explain how trim works in more detail.
Enjoy!

Part of the Boeing philosophy is that you should always be able to see what the aircraft is doing... ...except with MCAS.

[@guguigugu]

MCAS was a horrible idea that killed hundreds of people. i hope someone will end up in jail for it.

[@Razor2048]

@@guguigugu Knowing how those things usually go, the FTC would likely fine them around $100,000 and tell them to try not to get everyone killed in the future, or it will be another $100,000 fine.

[@RMR1]

@@Razor2048 It would be a lot more than $100K, but you're right, it won't be much. Or, more importantly, enough. Companies consider most fines handed down by regulatory agencies to be nothing more than the "cost of doing business." They're a joke and change nothing. Until prison sentences are a real and consistent threat, breaking the law to increase profits will be a standard operating procedure in virtually every industry, not just aviation.

[@robharris5467]

I imagine a certain Air France flight would have survived had the Captain been able to see that the PF was pulling back on the sidestick and worsening the stall condition.

[@anneangstadt1882]

MCAS failed because Boeing deviated from this longstanding philosophy, without investing in or having the know-how to do a "pilot-opaque" self-correction feature properly. And thanks for explaining those trim wheels.

THANK YOU!!!! A few decades ago, when I was about 13 years old, my dad worked for Piedmont Airlines. While coming home from my grandma's house in Seattle, the last leg of my journey, Richmond to Greensboro, was full. Employees and families fly "Space Available", and since that was the last flight of the day, they didn't want me to have to wait in the airport overnight. They put me in the navigator's seat in the cockpit. I was in hog heaven. Since that night, I have wondered about those wheels. It has been in my mind for over 40 years now. Thank you for cluing me in.

[@eric8135]

I am a machinist, I worked at a place where we made parts for the trim screw and rear termination fittings. Let me say they are massive and tight tolerance for precise movement. Plus they will replace them after a time, a plane went down in the 80s or 90s due to the trim screw getting stripped out.

[@wotan10950]

Eric Yes, that was the Alaska Airlines MD-80. The airline was using an unapproved lubricant for the jackscrew. When it failed, many people died in the accident off the Los Angeles coast.

[@user-lv7ph7hs7l]

I think they even just didn't lubricate it for too long. They where spacing out maintenance more to save money.

[@Cragified]

Didn't lubricate it and didn't inspect it as required by the maintenance schedule. The pilots actually tried to fly the aircraft upside down at the end when it rolled over. And by that the FDR shows forward stick inputs and asymmetric throttle commands all the way to impact. They never gave up.

[@lzh4950]

@@Cragified Not sure how accurate my memory is, but I recall it being mentioned too that the pilots manually activated both jackscrew motors (via the suitcase handles) simultaneously, while activating them one at a time instead might have reduced stress on the jackscrew & reduced its chance of failure?

Many, many thanks for those short videos illustrating the point you're making with actual cockpit views of the controls in action. That helps us understand. Many thanks also for helping even non-pilots like me better understand what is happening when we're flying. I was on a commercial jet coming into Seattle's airport (SEATAC). We were in the final approach, when I sensed the engines revving up. I knew something was happening even before the pilot came on the PA informing us that the flaps on one side had fail to lower. I knew enough to know all that meant was a faster approach and a longer landing run, but quite a few of the passengers around me became worried until me circled around and made our landings. Knowledge isn't just power. It can also have a calming influence in tight situation.

[@mattw8809]

Thank You, well explained, no more wondering for me at stop lights !

[@tedex8100]

I feel so safe knowing men and women as highly trained as this pilot are flying us around. I can't imagine the brain power they possess. Love the videos,subbed ages ago.

[@lespaulx]

Basically, those wheels are FEEDBACK from the machine to the pilot. The pilot can "feel" the behaviour of the stabilizer by just being there in the cabin without even see the wheels turning.. some finest ergonomics right there!

[@speedbird9313]

Ele Pequis Well..since you can actually turn them they are a bit more than feedback..

[@Prowlgmail]

soon as you start talking talking about trimming I started thinking about trimming the Bridgeport or milling machine. so knew it had to do with leveling. trimming the word we use to say we are leveling the head of the machine so you can get flat cut.

[@markusdaxamouli5196]

It's Amazing how I know most of what Mentor post..but he does it in such a way that I'm mezmerized. Great videos and awesome presentations and topics.

[@naeemtailor4052]

Thank you captain..for the giving a knowledge of trim wheel

[@angielabelle9541]

I was taught that another benefit of moving-stab trim (beside increased authority) is reduced drag- without trim, or with tab-based trim, the elevators are constantly deflected into the airstream, producing drag.

[@petep.2092]

True. Although the stabilizer, when trimmed, produces the same aerodynamic "lift" force that the deflected elevator was producing, it has a much larger surface area than the elevator, so it produces that force with a much lower angle of attack to the airstream, and if you look at the graph of drag vs. angle of attack you'll see that the drag increases substantially with high AOA. Thus the low stabilizer deflection is more energy-efficient than the high elevator deflection to maintain the desired pitch attitude.

[@user-rm9xb2sc3o]

[@TheSteinbitt]

The trim jack screw, after watching a lot of air craft investigation stuff on YT, this is the one component I fear will break the most...

[@Deploracle]

That is why it's a component that is always checked for wear, and replaced regularly.

[@TheSteinbitt]

@@Deploracle I'd still like some redundancy!

[@wilsjane]

It was the jack screw on the rudder that caused those crashes in the past. The maintenance manuals did not mention that de-icing could remove the grease. Once the threads stripped, pilots continued to run the motor, ultimately causing the stop to sheer, leaving the rudder flapping in the wind. I think that all pilots should be required to spend 6 months in the maintenance shop as part of their training. It would give them a better understanding of potential faults and how to work around them. As an engineer, when I see some of those crash reconstructions, the moment I see the pilots continuing to try to operate a faulty component, I think, for f**k sake don't do that, or the whole thing will fall apart. In many cases, if they had understood the fault and worked around it, they could have got the plane back on the ground. That was exactly what happened when a Japanese plane hit a mountain with no survivors. Had they have turned the autopilot off and adjusted the thrust on one engine, they could have avoided the mountain. It was not a sudden problem. they had more than 40 minutes to work out how to steer the plane, but they made no attempt to do anything. Had they cleared the mountain, landing would have been difficult, but not impossible, Dropping the plane into shallow water off the coastline may have been their best option. At least it would have prevented a fireball if they were unable to line up on a runway and many lives would have been saved.

[@davidkillens8143]

I was on a short up-and-back flight in a Canadian Air Force Buffalo. Comox to Anchorage. On the way back there was about twelve of us in the aircraft, and we noticed that the pilot was just sitting there, casually trimming the elevator (it was 100% manual). We moved aft, and chuckled as we watched the pilot automatically spin the wheel to compensate. Then all of us silently moved up front, and to our glee, watched the pilot spin the wheel the pother way. This game went on for abut three cycles, then the pilot sat up straight, looked back at all of us huddling right aft. The jig was up. Hard up elevator, then hard down, and we all felt zero G, then the hard floor.

[@andkyrit]

Mentour, I remember that when the 737MAX crashes happened, people where talking about the pilots not being physically strong enough to fight the actions of the MCAS, but I didn't understand what exactly they were trying to move manually. Is it this trim that they were trying to roll manually? If yes, why?

[@GreatMasterGaming]

It's possible to move the trim wheels manually when you have issues like runaway stabiliser you can disable the electric trim and you do it by hand.

[@jmcdonne]

Yes, it was this trim. MCAS was adjusting the trim to be nose-down because MCAS (due to the faulty input of an angle-of-attack sensor) thought the plane was going to stall. MCAS overrode the electric trim switches. There are cutout switches which disable electric trim control (MCAS or switch), and when these are activated, the trim could be changed manually via the wheel. However, the aerodynamic forces may have been too strong for the pilots to turn the wheel.

[@htcmlcrip]

Yay at last! Found it. This was bugging me ever since I seen his first video lmao

[@Bitterrootbackroads]

I watched video and read comments, most of which are compliments for explaining it all. BUT my question is still NOT answered. How exactly are the trim wheels / cables connected to the stabilizer? Are they simply turning the motor shaft that (through a gear reduction mechanism) turns the jack screw controlling the stabilizer? Or are they adjusting something that is between (in series with) the Jack screw and stabilizer? Imagine these scenarios-- 1. Trim motor becomes electrically disconnected---but motor , gear reduction, and Jack screw are all free to turn. This would manifest itself by the trim control switches on yoke having no effect, correct? Do the trim wheels simply rotate motor armature and adjust trim the same way motor would if it had power? 2. Motor, gear reduction, or jack screw are SEIZED / LOCKED UP SOLID? In this case the manual trim wheels and their cables if connected to stabilizer as described in scenario 1 are also seized and locked, correct? 3. Assume the nut being driven by the jack screw has the threads completely stripped out--- (similar to the Alaska airline incident). Motor is still turning jack screw but trim is NOT being adjusted. Are the trim wheels connected to something that is still able to adjust trim? 4. AOA sensor failure, computer failure, or an electrical short, cause an un-commanded trim adjustment to maximum jack screw travel--- Are the manual trim wheels / cables able to counteract this action and return stabilizer to a somewhat neutral position? I guess WHAT I'M ASKING is--- Are the trim wheels / cables and the electrically driven trim controls "REDUNDANT" ? Or is trim control (to use NTSB bridge failure assessment terminology) "Fracture Critical" where the failure of a single link in the chain causes the chain to break.

[@pfsantos007]

I can only answer number four based on the checklist for runaway trim. One of the steps is to use the cutoff switches and if the wheels don't stop to grasp them with your hand so yes you can stop them then turn the other way.

[@RazvanMaioru]

The others also seem to be the case, but the third would count as a catastrophic failure and the second is extremely unlikely to happen without being caught by maintenance first.

For some airbus models I have seen in simulators, there are those spinning wheels, but in that simulator, the trim is on the control coulomb for the 747

[@Tekloth]

In the Airbus family for example, the A319, 320, 321, 330 and 340 still have the trim wheel, whereas the new A350 doesn't.

[@albertopinciroli5331]

[@dustinwalden7091]

I believe trim is controlled on a control on the yoke and the wheels are there to both show that the trim is being adjusted and as a backup manual adjustment since there is a manual trim wheel in say a Cessna. My best guess.

[@toml9967]

Mentour, after you land do you set trim back to normal position or keep it set where you set it when you have landed?

[@dalewong7643]

I only know that S7 airlines' procedure is to trim it to 5 units after arriving at gate.

[@harrydoherty8299]

i only know on a 172 cessna there marking for takeoff position .

[@RazvanMaioru]

In any case, it gets set for takeoff before departure, so whether they reset it after arriving or not makes little difference.

For some time when I worked for Boeing (73/57 Flt Deck design) I knew they were for trim but didn't know the philosophy for being there. Thank-you for clarifying it.

The way the plane would show you, through the hardware in the cockpit, what it's doing would make it so much nicer to fly for me.

[@HungryGuyStories]

So in layman's terms, the trim wheels keep the airplane in balance as airspeed changes, it climbs and dives, and passengers move around inside the cabin?

[@HungryGuyStories]

Love your channel!!! Very interesting and entertaining to learn what goes on behind the scenes as I'm strapped inside a metal tube full of liquid explosive hurtling through outer space at 600 MPH :-/

[@gomphrena-beautifulflower-8043]

Hungry Guy • Oh, great. Now I know when I get up to visit the restroom, the pilots will be grabbing that wheel and saying "Oh no - she's up again!" rofl

[@shehulsuratwala2684]

May be also due to constantly changing fuel weight , trim is required .

[@souocara38able]

As AirSpeed changes, yes. When passengers move around inside, no, unless 50 or a hundred of them all move at the same time. When the plane climbs and decends you don't trim it to level. You trim the plane to level to adjust for the static loading of fuel, cargo and people. Not for a few people moving around during the flight. If fuel Burns off on evenly you would trim to adjust for that as well but I think that they would either burn fuel evenly or move fuel between the tanks to keep the loading level. In putting trim would increase drag and that's not efficient. it's better to keep the plane equally loaded whenever possible

[@46monkeyes]

I wondered if something like clothing can get caught by those wheels spinning and mess up the trim wheel.

[@renevanoyen3817]

[@harrydoherty8299]

i’ve seen the trim wheel move upon flair and landing . what is making it move? the pilots thumb on the control?

[@MentourPilot]

There shouldn’t be any trimming during the flare. Not ever.

[@HEDGE1011]

harry doherty If it's moving, the pilot is trimming but it is a very bad technique and is strictly forbidden in some operations. Some pilots trim in the flare in an attempt to get a really smooth landing, but this can result in long floats down the runway, tailstrikes, or in the case of a go around extreme difficulty controlling the plane when power is added.

[@HEDGE1011]

Bobby Paluga Yes it can. The B-737 has a very small cockpit and the trim wheel is very close to where your inboard knee naturally sits. It has a knob that's retractable and even when it's stowed it hurts when it hits you. It's an antiquated system that's been eliminated in newer Boeing products and while it exists in some other aircraft it's not so obtrusive. It was one of my least favorite features of the 737 (and 727 too).

Nope. It's not rotating at 1000000rpm or high speeds. It moves but it has not much power and spee

[@bobbypaluga4346]

Pilots do not wear their suit jackets not their hats when they sit down to fly the aircraft, most commercial pilots wear short sleeved uniform shirts, it makes you feel like you have less resistance to moving your arms up, down, back, forth etc. some "more by the book" pilots wear long sleeves, but I see no way the buttons on a long sleeve shirt could engage a moving trim wheel. If you have been brought up to think it's not proper to wear short sleeves with a suit or sport coat, like myself, because fashion dictates there must be 1/2" of shirtcuff showing with the jacket on, never wear short sleeved dress shirts period

"....will constantly show you what it's doing." ..............except for the mcas system, yikes!

[@stimproid]

The MCAS system trims the stabilizer...so yeah...you see what it is doing.

[@wrightmf]

Yes! This answered my question what those spinning wheels are for.

[@brianb4942]

This is a great insight not just in the Trim Wheels but the difference between Boeing and Airbus!! Cool. Thanks for the great vid

[@joka2486]

One word. Trim.

[@sergevivier2023]

Airbus A320 family have the same stabilizer wheels sir.

[@MentourPilot]

No they don't. As far as I know.

[@microbladehaiza]

A320´s, A330´s & A340´s do have trim wheels which are connected via cables to the THS. Yes, the Airbus is using autotrim but it is still turning the trim wheel while trimming. The first Airbus without a trim wheel is the A380, but also there is an indication for THS position, just on the PFD instead of the center pedestal.

[@sstroh08]

Not that it is 100% accurate, (but it seemed they did their best to be as accurate as possible) but in the movie "Sully" at the end when the Airbus pilots were attempting to see if they could make Teterboro or back to LaGuardia, I can remember the trim wheels spinning during such. That aircraft was an A320.

[@topethermohenes7658]

they do have THS on the center pedestal it just doesn't make a click sound whenever the autopilot moves it. and there are no THS control on the sidestick so pilots have to manually move the THS on the pedestal on direct law (the lowest level of automation)

[@HEDGE1011]

Mentour Pilot They do. I've flown both. The big difference is the A-320 requires hydraulics to move the stab. The other big difference is they move slower and are completely enclosed in the center pedestal so only the top quarter or so sticks out. You CAN manually trim with them but after setting TO trim on the ground it's normally automatic for the rest of the flight. It is a very good system and has never once injured my knees or fingers.

[@artword6185]

You sir have a talent in explaining things. Thank you!

[@tejaschavan5604]

Classic way of explaining stuff. That was awesome. Always wondered what really that wheel does. Now this video explained a lot.

[@fawadtalib6749]

I think the trim wheels works the same in A320 in an (Airbus).

[@avamendez1272]

Fawad Talib yes, they serve the same function. we set them once prior to takeoff, in the air, the trim system is fully automatic on the A320

[@ThomasDanielsen1000]

The very big difference is, that an A320 trims itself, not just with the autopilot on, but also when you fly manually. Only in case you have certain failures, do you have to trim it yourself. And in the A320 the only way to change the trim is by actually moving the trim Wheel (like in the Cessna).

[@moagisiisaac2359]

Fawad Talib in airbys uts automatic

[@harte13689]

TL;DR: TRIM WHEEL

[@nyyankees4296]

very insightful actually. I like the aircraft is constantly telling you what its doing

[@Peter1Europe]

Good video.I've been always wandering while going through the cockpit .

[@HOWCALL]

why we mostly use flaps in landing and takeoff (why not during the whole flight)???

[@thijmenschoenmakers2532]

HOWCALL because an aircraft flies to fast to use flaps the whole flight. Also for exaple, in the 737 flap use is not recommended above 20.000 feet.

[@HOWCALL]

Dutch Flight Channel thank you. but do we really need flaps above 10000-20000ft ??? I mean flaps are required on high altitude or wings of plane product enough up lift for plane??

[@thijmenschoenmakers2532]

HOWCALL Well, no we don't because we use trim. But by reading your question I thought you ment why we don't use flaps the whole flight. So that's why we don't use flaps the whole flight.

[@HOWCALL]

Dutch Flight Channel thank you

[@danielhandle4061]

the reason flaps are only designed to be used at low speeds is because the wing without flaps "engaged" has a shape that is good for cruising at high speeds and altitudes, which the shape with flaps down has a good shape for flying slow.

[@BHRxRACER]

yo, consider adding borders to your text and making it bigger so it becomes readable in the thumbnail.

[@beachforestmountain4269]

Excellent tip, BHRxRACER. Adding stroke outlines to text is very important in graphic design, especially in video design, because it means that no matter what the background is - the text will be easily readable.

[@BHRxRACER]

Well, only a little. You need high contrast. Red text with white border, yellow text with black border, white text with black border, etc. Whatever the color is, it needs to be different from the rest of the picture. Now you're using silver and black, which are very close together and also similar to the background picture.

[@BHRxRACER]

No probs :) Enjoy flying.

[@UltimateMTB]

《FPA》 《FuturePilotAditya》 wait..... are you Aditya from Vattastic?!? We did a group flight at 2am your time a week ago :)

[@jayp8798]

Thank you for sharing aviation knowledge and explanations, its awesome and appreciated ... god bless

[@elenacolon3880]

THANK YOU CAPTAIN I was curious about that wheel

[@HOWCALL]

But in the flight simulator we do not feel any force so how should we know how much stabilizer is required to stable the pressure ???

[@danielhandle4061]

its gonna be really hard to hold the yoke in place if its out of trim :) (if its a "real" flight sim, not an at home one)

[@BringerOW]

HOWCALL If you use a joystick and you need to constantly make inputs to have a stable flight attitude, then you know you should be using the trim.

[@Avantime]

You really can't, unless you have a $2000 control loading yoke, like the Iris or Brunner yoke. For aircraft with fly-by-wire and a yoke (e.g. Concorde) they use a similar thing called an "artificial feel" device. All other gaming yokes simply have a spring that returns to center.

[@ezymarkz]

I guess it depends on the flight simulator. I've flown a proper flight simulator (b737-800) and the yoke feels it is "fighting" against you. On my home PC the best way I find the plane is out of trim is reading the attitude indicator or when I find I'm constantly having to make corrections on the yoke.

[@HOWCALL]

JetMechMA thanks bro

[@jacobnathanielzpayag3885]

Hey Airbus dudes can your planes do this?

[@djvendetta2325]

I'm pretty sure all aircraft can trim

[@HEDGE1011]

Jacob Payag Do what? Trim? Yes. It's totally automatic. It works very well and unlike when I flew the 737, I've never been injured by the trim in the Airbus.

[@johnford5568]

Can never have too much situational awareness, bravo to boeing for staying with the classic controls even when automated, keep on eye on that computer. As in the terminator movie skynet, when autopilot suddenly becomes self aware and decides we are not fit to live, its good to know that immediately.

[@thomasjoseph6007]

Fantastic ! Thank you for sharing your knowledge. God bless.
