<p>I think understanding the mechanics of flying helps. It isn’t magic holding the plane in the air and turbulence is just buffeting while flying.</p>
<p>I suggest looking stuff up until you’re conversant but the basic idea is simple (in extremely condensed form):</p>
<p>Look at the wing of a plane. The top is curved. Like a bird’s wing. As the plane goes faster on the ground, air passes below the wing and above the wing (or you could say the wing cuts through the air, so some goes below and some above). Look at the shape again. The air that goes over the curved part has farther to go. That’s pretty much all there is to it. As the plane goes faster, the air flowing over the top has farther to go. That is what generates the lift which flies the plane: the pressure above the wing is lower than the pressure under it and when that pressure exceeds the weight of the plane (and drag and other complicated stuff), then it rises off the ground. This is an application of the Bernoulli Principle, which you test each time you put a finger over the end of a hose to shoot it further: the speed of the water flow increases and that decreases the pressure. On a plane, the curved wing means the air needs to cover more ground in the same time, which means it moves faster, which reduces pressure above the wing. And the rest is displacement like from Archimedes: stuff floats because it displaces more water than it weighs and stuff flies because it has more lift than weight. Lift in this case is essentially the same as displacement. Do you question why boats float? Or that they’ll continue to float when they hit bumps?</p>
<p>So turbulence is bumps in the air, really the same as bumps in the pavement. The plane is flying not because the air is smooth but because the airspeed is so high the plane generates a lot more lift than it weighs. Another way of thinking about this is to understand the plane is essentially being held down, not up, once it is up; they adjust the flaps and speed to keep the plane from rising (unless the air gets really thin, which isn’t an issue for regular planes). </p>
<p>In other words, the bumps don’t affect the lift that flies the plane. And the plane itself is so over-engineered for strength that it can fly on 1 engine, can lose big parts, etc. and still fly. And what is a bump? It’s very often just a small shift in pressure, meaning higher or lower pressure, so the plane moves up or down slightly or jiggles as the lift varies. It feels like a big jolt because it’s a big plane and that big thing translates motion to the small you inside so a 10 foot lurch feels like 100 feet to you. But that’s all it is: just bumps in the invisible road. </p>
<p>BTW, when I was tiny, I was used in a medical paper because I got airsick in a blizzard that rocked the heck - according to my dad - out of a DC-3. It was then believed airsickness was in your mind. I was one of the examples, a sleeping infant who suddenly vomited, to show it was a physical response.</p>
<p>Also btw, this simple mechanical setup also explains why each sport gives certain kinds of bodies an advantage. A pitcher’s arm extends so when he/she delivers the ball, it makes an arc. A short pitcher’s arm makes a smaller arc than a tall pitcher’s arm. Say they both move their arms at the same speed. That means the hand of a tall pitcher covers more distance in the same time, which can only be done if it is moving faster, and that means a tall pitcher throws harder with less arm speed and thus less effort. The tall pitcher’s hand is moving faster because it has to cover more distance in the same time. This kind of analysis is done for every sport and every position. Rowers are tall because their longer reach means they pull more water each stroke and the boats hold up the bodies so the extra weight isn’t a big penalty. Short cyclists do well in hill stages because they weigh less and shorter legs go through a shorter pedal stroke, which is easier than a long stroke under hill pressure. But on flats and smaller hills, length of stroke helps the taller riders. These are the same idea as the curved wing translated: as I said above, the curved wing means the air needs to cover more ground in the same time, which means it moves faster, which reduces pressure.</p>
<p>Sorry if this is pedantic for no reason.</p>
