Have you ever wondered what the "Back wings" on the Boeing 737 actually does or how the Pilots control it?
In this episode I will give you an insight into the Vertical and Horizontal Stabiliser.
I will be discussing how the different parts work, what their purpose is and what could happen if the pilots are not using them correctly.

@paulgracey4697 5 лет назад

You answered a question I had had for some time now. The 737 is perhaps one of the last large commercial aircraft to have mechanical linkages as backup to the servo-controlled hydraulics. Airbus uses fly-by-wire computers with massive redundancy if I am correct. So that begs the question of how the much much larger Zeppelins moved their even more massive control surfaces in the days before hydraulic servos even existed. I do know the answer, which is that they had smaller winglike surfaces both above and below the elevators for instance, that worked like the tail surfaces of a small airplane and essentially flew those huge balanced airfoils into the positions needed to change the direction of the entire airship. The rudders (top and bottom) worked the same way. While that method worked within the speed regime of those vehicles it was slow to act. Not a big problem when lift was accomplished mostly with buoyancy but for large heavier-than-air craft, it could not be used much.

Love your channel and videos. How you explain things is very refreshing and audio quality is spot on. A small model airplane would be a perfect prop in explaining the control surfaces and their affect on the airplane. Don't get me wrong, your arm works well too! I'm only a simmer, but have learned so much from your videos. This Wednesday I'll get the chance to go up in a small GA airplane for a 'Discovery Flight'. My wife gave it to me for my birthday. I'm 70. Not exactly sure what the flight will entail, but I hope the pilot will let me do a little maneuvering of the plane, in flight so I can put some of what I've learned in the simulator to a real world encounter. Not sure what plane it will be, but I'm assuming it will be either a 152, or 172. I live 2 miles from a small GA airport, and on the weekends there's lots of activity as I can hear and see the little Cessnas flying around. The downwind leg is right over my house as they approach base. In the summer I can sit on my deck and watch the pattern and turns being made. I think a lot of touch-n-gos are being practiced. I've got almost 400 hours using my sim (MSFS), and feel pretty confident on how to operate a small plane. It should be a lot of fun. Thanks again for such an informative channel and also for the quality you put into making them very enjoyable. Happy flying. :)

@briancox2721 5 лет назад

Good video, but when you say "momentum," you should be saying "moment." The first is a conserved physical vector quantity equal to the body's mass times it velocity. Forces acting on a body change its momentum. Moment, also known as torque, is a force applied offset from the center of a mass of a body which causes rotation. "Moment" is used primarily when talking about structures or other objects which are not intended to continuously rotate. "Torque" is used in rotating systems, such as an engine, to describe the twisting effort on a shaft or similar object. So, in a turbofan aircraft such as a B737 on takeoff, you would have torque from the engine core causing the fan to rotate, providing a thrust force on the structure of the aircraft, which causes both a pitching moment about the aircraft center of gravity and increasing the aircraft's momentum, causing it to accelerate down the runway.

@garrettmineo 5 лет назад

True, but we knew what he meant. I love these lessons, thanks.

@gyes99 5 лет назад

I noticed also that the term "momentum" was used incorrectly. Momentum also refers to a rotational moment of inertia, the ability to resist against applied torques (or moments?). The english language is not very unambiguous or precise with those terms.

@gyes99 5 лет назад

@James Smith I hope, aircraft designers and engineers know better, and do not respond like: "We all know it would fly."

@ddegn 5 лет назад

Rubbish- "we all knew". Were that so, why would you pass by here? Facts still matter. Some confusion also with pressure and force- quite different critters, not hard at all to get straight.

A person Next to her heard me and commented it was the auxiliary power unit and we realized he was a pilot studying his business sheets. I felt like bugging him with some questions but knew he was deadheading in civies and needed rest & to study his sheets to prepare for his next flight. So we left him alone. But nice to know he was there. We were on a airbus 320 .

There were several incidents with the 737 rudder caused by uncommanded deflections which led to at least 2 fatal crashes, United Airlines Flight 585 and USAir Flight 427.

@WilliamJones-Halibut-vq1fs 5 лет назад

This was partially caused by Boeing saving money on the 737 design by not installing a split rudder in the same manner as the 727 or 707. The 737 has always compromised redundancy and therefore safety in the interest of cost.

@JanButterfeld 5 лет назад

Great Info on this Channel, also for Aviatic laymen :-) What stuns me, the Fin (vertical stabilizer) can be ripped off of a plane by airstream alone (as shown at 15:10). But then, about Wings it is known they are designed to never brake. Now I'm wondering if bad wheather or turbulence conditions can make Fins breaking away, accidentally. As I learn, bad maneuvering conditions (which could occur in severe turbulences?) would easily rip them off. In other words, why are Wings built so strong (to never brake), while vital Fins aren't that strong, so they can brake eventually.

@robertbarlow6359 3 года назад

When mentioning balancing the turn with the rudder, I've wondered if there's much adverse yaw (secondary sideslip type yaw) from the down going aileron of the uplifting side wing? That is, if the automatic or manual rudder inputs weren't implied? With gliders/sailplanes for example, the aircraft would sort of side slip out of the banked turn, without plenty of rudder.

@luckyirvin 5 лет назад

@stracepipe 2 года назад

I always thought that banking the aircraft resulted in some of the vertical lift component now applying a centripetal force to the aircraft resulting in the turn (when used in conjunction with the rudder input). That reduction in vertical lift also results in a loss of altitude during the turn. On a separate note, momentum is mass X velocity (kg.m/s), where as moment is force X distance (Nm), which is I think what you are referring to? It's difficult when English isn't your first language, you do a first rate job.

@girishkv1785 3 года назад

The way you explained is ABSOLUTELY FANTASTIC captain !!!!!!!😊... You have explained about the trim and control in detail... Just one thing could have been added when u discussed about horizontal and vertical stabilizers.. These surfaces are providing the stabilizing force and moment for stabilizing the aircraft and coming back to its original position when the aircraft disturbed from its intented path due to air turbulence, to a great extent without pilot or computers intervention to correct the flight path. Its an inherent quality of an stable aircraft !!!!
