Vr: The speed at which the pilot begins to apply control inputs to cause the aircraft nose to pitch up, after which it will leave the ground. My question is: why on airbus computaion EFB(electronic flight bag) there are so big margin of rotation speed in cofiguration flaps one, from 155kts till 175kts(on the same aerodrome and on the same runway) According to formula of equation lift L = (1/2) d v2 s CL Where: L = Lift, which must equal the airplane's weight in pounds d = density of the air. This will change due to altitude. These values can be found in a I.C.A.O. Standard Atmosphere Table. v = velocity of an aircraft expressed in feet per second s = the wing area of an aircraft in square feet CL = Coefficient of lift , which is determined by the type of airfoil and angle of attack.

I've always heard airspeed described as the speed of the plane relative to the air and that doesn't make sense to me, but after watching this I see that it is the speed of the air moving over the wings and that makes sense. I finally understand the difference between air and ground speed.

So if a plane's maximum speed is stated as 500 kmph, it basically refers to ground speed? Also, it seems airspeed doesn't refer to how fast the craft is moving, merely the speed at which the air is flowing over the wings?

If there was enough tailwind, could a passenger plane break the sound barrier? I hear it quite often, but then I think how can it be?

With Headwind of 10 Knots and Groundspeed of 80 Knots.

Aircraft are more efficient at high altitudes and it also the wind is stronger generally

​@@PILOTCLIMB Yes I know this was just an example. What Im asking for is an explanation of the physics/math involved because it is counter-intuitive.....we generally think a plane flies "easier" or more efficiently in a tailwind, but your example shows that tailwinds actually decrease airspeed. So it would seem that in your example a pilot would have to increase thrust in a tailwind to maintain a given airspeed to prevent stall. Im sure Im missing something as Im not a pilot, but I would like to know the physics explanation of this.

In other words if the 10kt tailwind suddenly dropped off to zero then the planes indicated airspeed would drop from 80 to 70. . . Hmmm just a hunch - answers on a postcard :-)

@@FSUmofo because in real life ground speed isn't constant. In real life planes stay between "stall speed"(minimal airspeed before losing lift) and "overspeed"(max airspeed plane can handle). So within that envelope getting tailwind actually increaces groundspeed.

You can picture the differences easier when think of a glider, a sailplane, planes I started to learn flying with when I was 13 y/o. These planes don't have any engine to pull them through the air, they only fly because they 'fall' due to gravity, gently though, with huge wings to produce the necessary lift to not really fall out of the sky. In these planes AIRspeed matters more than in any other, or better, the plane's attitude in the air, as you can't just make up for lost airspeed - let's call it airflow for the moment - by just pushing a throttle forward to gain more airspeed, airflow around the wings, if you had lost speed. You could only push the nose down to gain more speed. Which results in a loss of altitude, whioch can lead to dangerous situtation near the ground, as you might can imagine. So, managing the planes energy state is key in soaring. There are set limits, normal and max speeds, but especially of a minimum airflow necessary around the wings and fuselage to make a plane fly. Any plane. And for my Bocian back in the days it was min 60 km/h and normal was 80 km/h. Doesn't sound really fast for a plane, right? :D And here's what could happen: if there's strong enough headwinds planes could appear as if they'd be standing still in the air, because the ground speed, the speed that is really the least important one for a piston engine plane, and especially for a sailplane, was so low, because the incoming wind from in front of the plane could generate enough lift alone in windy conditions, so that the plane was barely moving. Compared to the ground. You didn't make much of a distance in relation to the ground. So that's what matters only, it doesn't make a difference for the necessary lift, if you move the plane through the air to generate the airflow around the wings, or if the wind is moving around your static plane with the same speed. Like they test aerodynamics in windtunnels in Formula 1. The car is standing still and they blow wind against and over it, as if it was going with 300 km/h. Samey. Same they can do with wings for planes, fuselages and so on. So, in order for the glider pilot to not exceed the max speed limits of his fragile sailplane, he cannot go just faster to go faster in relation to the ground, when his airspeed indicator tells him, that he's 'going' with 80 km/h. Unfortunately not going anywhere when the wind came with 80 km/h from in front (which was 22 m/s). That would relate in 0 km/h ground speed. If he pushed the nose down to not have to stand still up there forever, he would then gain more indicated airflow... um speed ... around his wings. Maybe 100 km/h. And this would mean he would go by 20 km/h in relation to the ground. If there's no wind at all he had to move the plane with 80 km/h to create the same airflow around the wings, which would result in 80 km/h in relation to the ground. And vice versa: when headwind slows a plane down in relation to the ground, then tailwind must make it faster. You have to subtract, not add, the tailwind from your speed through the air in order to know if you have reached the necessary airflow/speed around your wings. Tailwind is taking airflow away from your wings. Wrong direction so to speak. A plane doesn't fly with airflow from behind. It works only the other way round. The more wind from behind, the faster you have to go (in relation to the ground!) in order to compensate what tailwind takes away from you. Headwind on the other hand, adds airflow around your wings - correct direction - thus you can go slower (in relation to the ground!) in order to generate the same airspeed around your wings. It's always only about the speed of the air around your wings. This result in different speeds of the planes the have to go through the air not only in windy conditions, but also depending on the altitude, as air gets thinner and thinner the higher you go, hence you have to go faster and faster to get the same amount of air (mass) around your wings per second, to not stall and fall to the ground. This is what true airspeed means. The true speed the plane is going through the air to compensate the lower air density is always higher as what your airspeed indicator shows you in your cockpit, the higher you are. To not have to calculate constantly which true airspeed you should have per altitude to generate the required lift, the airspeed indicators in general aviation planes show the so called indicated airspeed, which is always the same, no matter the altitude, as it works independently from air density. And true airspeed does not. On the ground TAS is nearly the same as indicated airspeed, the higher you are, the faster the plane not only has to go to have the same, constant IAS, but it also can go faster, thanks to the thinner air, which produces less and less resistance the thinner it becomes, but unfortunately it also becomes less and less powerful. ... t.b.c

... And last but not least here's another example, how you can picture what's happening with the air around (mostly beneath) planes: think of a water skier (not surfer!, It have to be water skies). Both water and air (as a gas) belong to the so called fluids. Physically. Which means, they share certain physical key properties, with the most important one being the capability to yield when so called shear forces are applied. A property solid object/matter doesn't have. They can resist certain amount of forces/pressure until they break, succumb, but will never give gently way. Like when you walk through air - it yields, it gives way, or you couldn't move at all. Water does the same. Its density is just much higher. But since they are both fluids, you can see water as the thickest air ever. It's harder to walk or even rund through water, than running through air, right? But it works. Until it's too fast, the force is too high, then it can't yield fast enough and it starts to resist to the shear force applied more and more. It will still be able to somehow make way, but it becomes harder harder. Now think of speedboat races, how these boats jump and jump and sometimes even crash. On water. And people gets killed, because water then feels almost like a solid object. So, back to the water skier, the same principles why he can "go over water" apply to air and make planes fly. Newton's action-reaction law, the third law, the law of motion. Every object generates the same amount of counterforce when it gets moved, that was needed to move it in the first place. If the water skier would just go fast enough on his little water skies - which are not big enough to keep him on the surface of the water when he doesn't move, he simply sinks in, just like a plane in air without lift, just not that fast - then he could run over it. Isn't that great? If you have ever seen what they're doing there to grab a rope and let a boat accelerate them, then jumping onto the water and if the shear force applied is high enough and the mass of the water displaced per second equals their own mass, then they don't sink into the water but can stay at the surface and have fun... as long as their speed doesn't drop below the necessary speed required to push water beneath it away fast enough, so thatz the water can't give way fast enough but pushes back against the skies instead. Some of it. That's just what a plane does when it accelerates through air. Its wings are accelerating such sheer masses of air and send them downwards, the wind profiles and angle of attack helps here to give it the correct direction, that these masses push back so hard into the opposite direction, that the plane can rest or float on it, even a 380 t heavy Boeing 747, an airbus and whatnot, just like the water skier on water. Just because we can't see the air and are so used to it, being around us constantly, doesn't mean it's not there. and doesn't have tremendous power. Hurricanes, taifoons etc. remind us now and then what air can do... just the same damage as water. Planes are not flying because of the ominous law of Bernoulli - that's what they thought us 35 years ago, because pilot instructors usually haven't studied physics and just teach others what they had been taught once, quite a catch-22 - otherwise plane couldn't fly upside down and would immediately fall out of the sky, or aerobatic planes couldn't fly either, as they have symmetric wind profiles to be able to fly upside down even better, but because they are pushing a fluid around, a fluid that yields, when you're going through it slow enough, becoming more and more and more resistant, the faster you become and thus the higher the applied shear forces will become. And at a certain speed air gets even compressed. Something scientist thought wouldn't be possible, until pilots found out. The hard way at first. Means, it accumulates insomuch in front of the plane, that it eventually gives way with a big bang... the famous supersonic bang. If you have ever heard one. So, on water the speeds are much slower than through air, but water is a great example, how stiff it can become, almost as hard as concrete, which is also why you wouldn't survive a jump into it, when you're speed into it would be too high... People have died from it. And same goes for our atmosphere: when astronauts make their entry into our atmosphere coming back from space, then the shuttles of capsules or whatever they're using start even glowing, air becomes plasma, the third matter that belongs to the fluids: fluids like water, gas like air and plasma like... plasma. :D Now compare the speeds of the water skier with the speeds of a plane. The higher the fluid's density the slower you can be to generate the same effect. Which is why planes have to be much faster than a water skier, or have to have much larger ... skies ... (their wings obviously) or both, in order to create the same effect, so that the air's reactio equals the plane's actio => moving mass attacking another mass - Newton would probably say. And now the other way round: The higher the density - like water's - the slower you have to be (the water skier) - and the lower the density, the faster you have to be (the plane) - and the yet lower and lower the fluids density becomes (at higher and higher altitudes) ... the faster and faster the plane has to go to not lose lift. Higher true airspeeds at higher altitudes and higher possible ground speeds too. That's all there's to it. Actually easy peasy, right? 😁 To all these people only the speed through the fluid matters in order to survive their ... stunts. Not the ground speeds. The latter is of interest for normal people if they want to know, when they will reach point B after they've left point A. And in this respect it also matters for airlines and all other engine driven plane pilots, as this time determines if they will be run out of fuel before they've got to B or not. If you ever happened to have flown with an airline, you're probably familiar with estimated times of arrival (ETAs). Pilots can never say for sure when they will arrive, as headwind will slow them down (in relation to the ground!) and tailwind will speed the process up. And the latter quite a bit, if they used so called jet streams at the high altitudes airliners are operating at. They're reliably constant enough and help them saving fuel, as they help to get faster from A to B. If you hit them in the correct direction, though. You wouldn't want to swim against the tide, would you? Same effect. The river coming from in front makes it tremendously harder to cover any reasonable distance. But for a plane it's irrelevant, to some extent. It want's to fly and not die. It doesn't want to go anywhere. It's just us. That's why we have them. :D

Airspeed equals ground speed account for wind. Altitude and the Earth rotating is never figured in that proves we don't live on a spinning ball.
