If you have been watching ANY cockpit video from the Boeing 737 you would have noticed those constantly spinning little wheels on the side of the pilot. What are they and why are they spinning so much? In todays episode I will explain the Stabilizer trim system on the Boeing 737 and, as always, I would love to hear if you have any additional questions or suggestions in the comments below.

When I read the title , " what are those spinning things in the cockpit" my mind when to somethings but never the trim wheels , at first anyway. I thought of the gyroscope,, Indeed you can't see it spin but in the aircraft I have been in during warm up you can sure hear the gyro spinning up. I have seen a few different models taken apart, one for ship use and one aircraft use gyro. Big , bulky, and very cool piece of hardware. I'm only guessing that aircraft today still all have gyros even with all the back up system like sat nav, etc. still a need for a stable platform on a moving pitching yawing aircraft. How about doing a video about that piece of tech for a video? Thank you, Paul.

That was fascinating. I wish if the pilots ever had to do manual crank stabilizer trim on a flight we could know it, so we could thank them for saving our lives before we exit the plane! But probably we would never see them at landing because they would be in there resting exhausted.

Every time I hear people saying "planes land themselves" I think back to this sort of video and how much the pilots can do to remedy the situatoin when the machinery goes wrong. I have the same feelings about self-driving cars, great when it all works on a wide-open interstate or autobahn, rubbish in a cul-de-sac in Britain or a cycle path in Belgium...

Just reiterates further why pilots don't want people up and moving all around while during takeoff I guess, they'd have to keep constantly readjusting trim if that were the case, and they got enough things to worry about at that time already. This is such a good channel even for people that aren't pilots, that just enjoy learning like I do

Thank you so much for your great video, Capt Mentour! Trimming the stabilizers was one of those things I could comprehend while "playing" MS Flight Sim 2000 (yeah! 20 years ago....) but I quickly knew something was probably off with the simulation. This brings me to the following question: when you say the stabilizers need to be trimmed to "take off forces the pilot needs to apply on the yoke" - do you mean that as the proper trim position is approached there is a feedback on the yoke/stick? To put it another way: can the pilot feel this proper trim position on the yoke (i.e. the yoke does not need to be pulled so much to maintain the required pitch angle) or it must be done with constant monitoring of the appropriate cockpit instruments to make sure e.g. pitch angle is stable without input on the yoke? Perhaps this boils down to the following: I am guessing the yoke is in neutral position when the aircraft is stationary on the ground. While is flight there would be forces acting on it - perhaps somehow proportional to the forces acting on control surfaces, right? So, coming back to my FS 2000 situation: I found it quite hard to trim (e.g. the B737 which I liked a lot to fly). I could feel resistance on my force feedback type joystick (no mechanical centering, everything controlled from the Flight Simulator application) when applying input on it, but trimming was reflected only on the cockpit instruments and the forward view generated by the simulation, obviously. I had no feedback on the joystick no matter the trimmer position. I have been wondering how it feels in a real aircraft ever since. Actually, I even asked one pilot here on YT (Capt TURBULENCJA from Polska ;) ) and got a bit disappointed. Turned out Capt Turbulencja primarily flies Airbus models and he said all trimming was automatic (yeah.... fly by wire, no wonder). Hope you could help me out with this! Thanks!

That reminds of the lost 3 aircraft of Alaska Airlines in one year. Three times of the same failure. The haven't lubricated the THS according to the AMM. They have skipped that task every second time. Of course that Airline didn't exists anymore. So it is the best thing when you see that THS wheels are moving. Even when they have a failure and can't hold stable. At that 3 Alaska Airlines the THS were stuck. They have forced it so much that the aircraft broke in two parts. After this episode of yours everybody here should watch that Mayday episode with the flight 261.

thank you for this great episode. i have a question to ask. since the jack screws are threaded rods connected one side to the electric motor and to the stabilizer arm on the other side. Considering that in case of failure the motor is jammed and can't rotate, how this link is released in order to control the stabilizer manually by acting on the wire attached to the rotating trims ? warm regards 🙏
Walid El Hed
Walid El Hed Ай мурун
@Speedbird thanks for the info 🙏👍
Speedbird Ай мурун
@Walid El Hed There is no lever.. This is how it works on the 737NG..The cables from the cockpit goes to a cable drum in the tail compartment. The cable drum moves the jackscrew via a gearbox, the cable drum can also move the jackscrew via a electric motor called the stab trim actuator. The horizontal stabilizer is directly connected to the jackscrew. The gearbox has two internal brakes and a mechanical clutch. Both of the brakes are ratchet type brakes. The clutch lets the stabilizer manual trim wheel input override the stabilizer trim actuator input.
Walid El Hed
Walid El Hed Ай мурун
@Speedbird i mean by arm the lever on which the jackscrew is attached and rotate to pull it up or down. anyway i'm asking about how the link is released when manually pulling the wire using the trims to change the stab. angle of attack

Why not install scales at the gate, separately for front and rear gear? This would give total weight, center of gravity. Of course, the data would be used differently for every aircraft design but this would seem to be a time saver. (i.e. labor saver and in the long run, a money saver.)

As a student pilot (many, many years ago), I was also taught to use trim for take-off without yoke input. So if you're in your take-off roll and you lose yoke input, you can take-off using just trim and rudder input. After take-off, we flew for almost an hour without any input from the yoke.
Paul Gingras
Paul Gingras Ай мурун
The way the flight instructor explained it was the technique was only to be used in an emergency. For example, you're about to rotate and you lose control of the yoke. In a Cessna 172 that would consist of a cable breaking. Now you have a choice. Do I abort? Or continue to fly and come around and attempt a landing. Well, it depends on how much runway you have left. I did some flying at Burke Lakefront in Cleveland, Ohio; the end of the runway was Lake Erie. No need to go for a swim.

So you mean the vertical steering doesn't work like horizontal steering? I mean, in horizontal steering, we have to turn the plane to the heading that we want, level it back, then the plane would stay on its new course (like on boat or car). But in vertical, if we wanna climb, we have to keep pulling up along the way until we reach desirable altitude, therefore we need the trim to release us from fatigue of that constant pulling up. Am I taking it right?

You also loose alot of finess from the horizontal stab when you need to use a big elevator angle. That's why the first way to fix the trim is to move fuel forward and backward to keep a neutral elevator angle. That's also why it's more efficient to keep the entire profile streamlined by pivoting the entire wing.
Speedbird Ай мурун
You cant move fuel forward and backwards in a 737NG tho😉
I have a question at that point sir, from our ATPL lessons we’ve learnt that if angle of attack increases then center of pressure moves forward. Is it possible to reach a point due to the increasing angle of attack that center of pressure exceeds and goes forward of center of gravity and then suddenly all the balance of the aircraft which was trimmed for pitching up,change?

Since these devises are directly linked to the issues on the 737 MAX (which I'm sure you're tired of discussing at this point, sorry), I wonder if you've discussed the angle of attack sensors that failed. It seems to me it's not just issues with the MCAS that needed to be addressed, but also why the angle of attack sensors failed. I understand the new revisions has the MAX using both attack sensors now rather than just one, but still the failure of the sensor must be fixed, yes? Has Boeing fixed or redesigned the faulty angle of attack sensors?

As a simulator tech in the Air Force, I was assigned to a KC-135 (Boeing 707) simulator. During some of the practice "missions", the instructor pilot would cause the trim wheel to run away. Although crude, the solution to that situation was to grab the wheel and prevent it from spinning. That wheel is turning with a fair amount of torque and the co-pilot would have to stop it with his bare hands.
Booboobear2388 2 ай мурун
While getting my private pilot's license, my instructor had me let go of the yoke. He then landed our Cessna Skyhawk with the trim wheel only (but use ailerons also). This to simulate the loss of pitch control (such as an elevator cable break). Then taught me to do it. It was difficult but I did it.
Booboobear2388 16 күн мурун
@Matthias Lipinsky - This was not the way one should normally fly. It is an emergency procedure in the event pitch control is lost because of a broken cable or something else. It is not easy but it is better than putting a crater in the ground.

MP great vid in fact close to AF. But I am still hung up on prior comment where I said I thought rear mount engines should require less pitch trim changes than under wing engines since the thrust and drag forces are coaxial rather than offset. So there would be a resulting torque around the CL or pivot point in the second case. I guess talking to pilots who have flown both types such as 737 and MD80-90 or CRJ could confirm if this is correct. I know Mad Dog pilots love the way those planes fly and are sorry to see them go to the boneyard. Any AF ideas on this?
