ashitano,

I'm not sure. My own interpretation is that the autopilot is always partially involved even before landing, and from the moment the gear lands, it automatically decides which airbrake to apply and how much to apply while watching the speed and direction data. In a sense, I think it is semi-automatic and operates in cooperation with the pilot. Otherwise, if the pilot is left to do everything, such as landing in a very strong crosswind, there would be too many operations for the pilot to handle at a moment's notice, and a major accident would result. In such cases, the autopilot may be involved in a significant proportion of the operations.

This is just my imagination.

Immediately after I wrote last time, I realized that the air brake was supposed to be activated automatically at the moment of touchdown. I looked closely and saw that at the moment of touchdown, the air brake went up by two and then up again by two. That would suggest that the brakes are being applied gradually. The first two brakes are used to keep the plane from bouncing back, and when the front wheels land, the other two brakes are activated, this time to apply more brakes to slow down the plane. Well, it seems to me that it is done with this level of precision, but another thing that bothered me was that when the first two actuated, they did not go up at the same time, or there was some laxity, or I thought ？ that was taken into account as well.

It may be a bit silly in detail, but you can see from the wings that the pilot is working very hard to balance the plane just before landing. But after landing, it looks like the wings of that part of the plane are going up to help with the brakes. I wonder if the control stick is attached to the front wheels after landing.

ashitano,

I am not very familiar with the structure of airplanes, so let me first confirm that the airbrake on the wing is generally called a spoiler. This is certainly to slow down the speed of the plane when it is flying or gliding, and is also called an air brake. Also, whenever a plane lands, it has to slow down, so I would guess that the spoilers stand up almost semi-automatically. At the same time the engine reverse thrust Reverse Thrust would be fully opened and this would have wheel brakes which the pilot would have full control of.

＞ After landing, the controls attach to the front wheels

I have no idea about this. The brakes on the front and rear wheels are applied by the pilot with his foot, just like in a car. Unlike a car, there is one brake pedal on each side, which can be controlled separately. So it seems that this is used to steer the front gear （ and front wheels ）, which have only one center gear. Therefore, I don't think it has anything to do with the control stick operation.

The story of the stick, well, if you ask the pilot, it's probably nothing, but we are amateurs and enjoy conversation with our imagination, I mean, it is the pilot's wheel brake, but it moves the vertical tail left and right during flight and serves to change the direction of the plane. I think it is the pilot's wheel brake, which moves the vertical tail left and right during flight to change the plane's direction. It might also act as a brake after landing. The control stick, like a car, has a wheel that rotates right and left, tilting the plane to the right or left during flight. I thought that after landing, it might go right or left on the ground just like a car. It is interesting that this control stick or brake plays a dual role in the air and on the ground.

ashitano,

I see what you mean.

I saw on YouTube or something that the pilot has two independent pedals at his feet, so I thought they might be used for landing. I will actively look into the role of the stick and pedals around the cockpit from now on. Well, Boeing still has a control stick located between the legs (!!!). \Airbus has long had a joystick on the side of the cockpit that is used with one hand. Therefore, the left and right hands are reversed for Captain and First Officer.

Therefore, pilots are usually divided into Boeing or Airbus group from the beginning of training.
