As a fan of Microsoft Flight Simulator, I did knot understand why they used this unit of measurement. It's cool how the aviation industry is similar to the naval one. Makes sense when you learn the history. Thanks for the video! (Sorry for the bad pun, haha!)
Rather than listen to a long explanation of what a knot is and how it's measured, here's the real reason. The first passenger aircraft were seaplanes. When wheel becamo common the tradition had already been firmly established.
There's a little tube that points forward that measures the force of the air pushing on it, along with a litrle hole on the side measuring the air pressure. The airspeed indicators mechanically subtracts the outside air pressure from that force from the forward motion through the airbto give you your airspeed.
The Pitot Tube measure airspeed. Its a little pointy contraption sticking out of the airplane front side. When air presses against it that rate of change of air pressing on it measures the speed. The concept was borrowed from ships in which the tube was placed in the hull and would measure how much water pressure asserts itself to the tube and that would calculate the speed of the ship.
Not at all. Nautical miles measure distance while knots measure speed. The nautical mile came from the distance travel in one minute over latitude. Knots was a practical means of measure speed in water.
1 knot = 1 nautical mile per hour. The two words sound the same but have different origin. Nautical come from Greek word 'Naus' which means ship. A sailor was known as Nautes. The Romans borrowed the word and used it as Nautikos to mean anything pertaining to ships. From Latin it go to French and French to English as nautical. On the other hand. Knot is wrong English word from tying a rope to form a round obstructions along the rope.
Old English had a masculine and a feminine word for two. The feminine was ‘two’ and the masculine was ‘twain’. On the Mississippi River in the 1800s, people still used the word ‘twain’ and when the depth of the water was checked to make sure that the rope marked the depth of two fathoms, the leadsman’s cry was ‘mark twain’ - literally a mark of two fathoms.

😁😁😁 good pun. Well knotted.
your narration is amazing. The quality is great too.
Thank you!
nice informative video! thank you!
You are welcome
thank you
Welcome
I didn't know N'golo Kante was an aeronautical engineer ..
LOOOOOOOOOOOOL
more like a knotical engineer
ha ha ha ha! I am loving this puns.
So you're the smart one in the Kante family
Ha ha ha ha! And the poorest.
Who's this guy, I need more explanation. I'm very slow 😢
But thank you very much
He is Mr. Black or Orwa. Your Data Doctor.
@@blackorwa I love the content 👌
@@SemDoesEverything Thanks a bunch!

That works too
Now the question remains, how do they measure that during flight?
There's a little tube that points forward that measures the force of the air pushing on it, along with a litrle hole on the side measuring the air pressure. The airspeed indicators mechanically subtracts the outside air pressure from that force from the forward motion through the airbto give you your airspeed.

Good God! Wasn't it not related to nautical miles or something
Not at all. Nautical miles measure distance while knots measure speed. The nautical mile came from the distance travel in one minute over latitude. Knots was a practical means of measure speed in water.
@@blackorwa yes, I used to think nautical miles per hour or something
1 knot = 1 nautical mile per hour. The two words sound the same but have different origin. Nautical come from Greek word 'Naus' which means ship. A sailor was known as Nautes.
The Romans borrowed the word and used it as Nautikos to mean anything pertaining to ships. From Latin it go to French and French to English as nautical.
On the other hand. Knot is wrong English word from tying a rope to form a round obstructions along the rope.
1 knot is 1 arc minute of longitude or latitude per hour.
Yes it is. Or simply 1 knot = 1 nautical mile per hour.
..and 100km/h is 1 gradian per hour by 1791 definition of metre
Cheers
Mark Twain = 2 knots 🤞
