If you don't know what airplane flaps do
what is interesting? I'm sure it is.

The landing in the last part of this video, one air break and some of the rest seem to be delayed. It feels like when the pilot sensibly applies the air brake, it doesn't react immediately.

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.
