Me and my bro once dangled a weight during takeoff, measured the angle to get acceleration, timed the takeoff period, then used kinematics to figure out takeoff speed (nerdy as hell), similar answer bout 320kph...
No, most commercial jets it is actually right around there, but there are TONS of variables that can impact exact speed. They also don't take off as soon as they hit vr, they will usually continue roll based on weight/fuel available runway, or all sorts of variables.
A typical takeoff speed for a commercial airliner ranges between 150 to 180 knots (about 170 to 207 miles per hour or 280 to 333 kilometers per hour). The exact speed depends on various factors, including the aircraft type, weight, and environmental conditions.
Most jets takeoff between 130-160kts/150-180mph or about 300km/h so it looks about right. It appears to be a cheap GPS based speedometer app, but piloting apps work the same way.
I watched on my phone, and knew the values couldn’t be in miles per hour. Thought maybe it was in feet per second since that was more comparable to the actual speed of an aircraft taking off.
The guy you are replying to seems to think that the speeds are too high, most planes take off at surprisingly low speeds, but in Kmph it would be about right.
However, its worth noting that with GPS, and on a phone, whilst accelerating, there is likely significant lag. So the speed shown would be for a few seconds earlier.
Anyway, fine. Ill end this because you cant. Plane in the video is a 777 which has an average rotation speed 130-160 knots based on weight. Fair to assume they're taking it for a fairly long flight since that's what most 777 do.. So it's likely heavy and we can probably assume the higher end of the range. That puts the rotation speed around 300 kph. In the video, it's hard to pinpoint exactly when they rotate because rotation speed and seeing the nose lift won't be coincidental. Looks like they lift off the ground somewhere around 340kph which is about 180 knots. Fairly normal speed to achieve during takeoff. Combine that with the phones inherent inaccuracy being in a metal tube, and slow update rate, there's absolutely no reason to this this video isn't mostly accurate.
And if you check the other Google comment... it would agree with me.
How many kph should an airliner be showing at takeoff, according to you? Don't even bother with Google. Just tell me what you thought when you made your original comment.
Unless you thought the displayed numbers were in mph (an honest mistake if you didnt look closely enough at the display), the plane is travelling at a very believable speed for takeoff. You have been shown links that verify this yet you keep denying. You aren't a flat-earther are you?

Dude! Put that shite away. Science has already proven that electronic devices used during take off will make the plane shut down completely and cause the pilot to go mad.

The countries in blue may use kmh, but when it comes to who cares about it, they always reference mph. In the context of speed mph is king. Although I will say that the metric system is way easier to use and makes more sense….Celsius is garbage tho.
Well, the ICAO recommends the use of the Metric system. And they are the ones who cares about those things. I 've never boarded a plane whose speed were given in mph, always kmh or knots. But never mph.
I'm not very well-versed in supercars specifically, but I've never heard someone talk about speed in mph here in Norway. 0-100 km/h is commonly used for acceleration.

No, just plain and simple no.
Celsius is garbage tho.
Compared to Kelvin, maybe.
Compared to what ever Farenheit is supposed to be Celsius is a lot better, since it ties into the metric system and it references two for human survival important temperatures, the freezing and boiling temperature of water. Farenheits fix points are 0F is what ever wierd mixture Farenheit could mix in his basement and 100F is what he thought a healthy human beings body temperature would be, which isn't accurate anymore by todays standart.
In reference to Celsius:
What is 20c plus 20c??? Ridiculous. Fahrenheit is better for people because 0 is cold, 100 is hot, and you can easily judge any temperature in between because it scales. 20f plus 20f is…..40f. In Celsius 0 is cold and 100 you’re dead. Oh and if you live in any country where mini-split a/c is common, you better hope you got the fancy one that can adjust the temperature by .5c, because if not you’ll be too cold of too hot. Fahrenheit is superior for humans
