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!

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.

  • 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.

  • 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.

    @angielabelle9541@angielabelle95416 жыл бұрын
    • 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.

    • 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.

  • 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.

    • 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.

    • 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

    • 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.

    • 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.

      @microbladehaiza@microbladehaiza6 жыл бұрын
    • 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.

    • 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)

    • 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.

    • 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).

    • 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).

    • 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

    • 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.

    • 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.
