Will Canada ever become the 51st State of America?

Heaven forbid we adopt a system that actually makes mathematical sense. Oh wait, we already have. Keep trying you can figure it out. You may get some blowback from BC, who I doubt enjoys measuring things using a system that is Imperial.

The US doesn't use Imperial measurements. Standard measurements, however...

Thanks for agreeing...finally.

Next-up knots at sea and in the air...discuss.

They were used to get around the silliness of trying to calculate Imperial/standard measurements on the fly.

That said we still have the odd dinosaur who likes to use cables and leagues in my industry... whatever.

A knot is a unit of speed measurement. It's original definition was based on counting the number of 'knots' tied into a spool of cord that unwound after a 'chip log' (essentially a standardized block of wood) to which it was attached was thrown overboard during a specified period of time usually based on the sand in an hourglass. The knots were usually tied 8 fathoms (48') apart, and the 'hourglass' usually counted either 14 or 28 seconds.

While the definition of the unit was modernized, it is still a unit of speed and not distance. It is applicable to both marine and air travel because they both move through a fluid (water or air). It is not an absolute speed, but rather a speed relative to the fluid in which you travel. You cover far less distance flying into a headwind than you do flying with a tailwind even though your speed measured in knots is exactly the same.

A knot, or nautical mile is based one the distance between one minute of latitude, just over 6k feet. And what you are talking about is referred to as groundspeed by aviators or speed over the ground by mariners.

A knot is not the same thing as a nautical mile. A knot is a unit of speed measurement and a nautical mile is a unit of distance. A knot is the equivalent of one nautical mile per hour. A knot however is not a measurement of groundspeed, but rather airspeed or speed through water. If the air or water is still then yes it would be equivalent to groundspeed, often the speed of the fluid is also measured so that a groundspeed can be calculated - what is known as velocity made good. Modern technology (gyroscope, GPS, etc.) has allowed the direct calculation of groundspeed so that is often used for navigation purposes. Yes, modern aviators and mariners will also express groundspeed in knots for consistency. The speed through the fluid however is very important because it directly affects how the vessel handles. The airspeed is what is important for lift, not groundspeed. The speed through the water directly relates to how the hull performs.

If you say you are doing 100 kts. that means you are travelling at 100 nautical miles per hour. Or 100 times the distance I gave you before. If we have a 10 kt headwind then our groundspeed will be 90 kts. Our GPS will show us that but our airspeed indicator will show us 100 kts.The same applies to a vessel except it will be current that affects our speed made good and not wind speed/direction.

I don't really care if metric is better or not. To just go and change a measurement system without the consent of the people, which worked perfectly fine, was my beef. I know of no one who asked for the change. Just like bilingualism, multiculturalism, foreign-aid, and massive third world immigration have and are still being forced on the people who never asked for any of them at a huge cost to those taxpayer's. In Canada, Canadians don't live in a democracy, they live in a politically correct dictatorship. Our Canadian politically correct fake and phony politicians continually show their contempt for the taxpayer's, and their tax dollars. Shameful indeed.

Why do they use nautical miles, and not just regular miles?

A private pilot can have any type of ASI in their aircraft but when they check the weather or flight plan they best know what knots are

 

A classic Russian gauge...no knots. Just km.

Perhaps this explains your interpretation and misunderstanding of history.

You should focus on discussing something you presumably know about - like smelly gas.

 

"Historically, it was defined as one sixtieth of the distance between two parallels of latitude separated by one degree." 

Yes...in the ol' sailing days there was the reeling-out of the knotted ropes...

Last I heard, there were 360 degrees in a circle....be it Earth or a Compass. But I understand that I MUST be wrong and you MUST be right.

Right?

:lol:
