Why do planes use knots?


Why do planes use knots? In modern times, a knot is a unit of speed that ties directly into the global latitude and longitude coordinate system. Therefore, in the aviation and nautical worlds, knots are oftentimes used in place of MPH and KPH since they are easier to navigate with.


How windy is too windy to fly?

With this in mind, horizontal winds (also known as “crosswinds”) in excess of 30-35 kts (about 34-40 mph) are generally prohibitive of take-off and landing. As far as how this happens, it depends on where you are in flight.


Can planes take off in rain?

In most rainy conditions airplanes can take-off and fly with no problems. This is true of even smaller general aviation aircraft.


Why do planes fly north to Europe?

Despite what many people believe, the answer actually has nothing to do with safety. The real answer is because going north may actually provide a shorter route. This is called Great Circle Navigation. Because of the curvature of the Earth, the shortest route between two locations may appear much longer on a flat map.


Can planes fly in rain?

While rain has a very slim chance of canceling a flight, there can be a minor chance that rain will delay it. Rain is just water, no matter the pressure. Modern aircraft can generate lift regardless of the heaviness of the rain. Planes can and will take off and land in the rain.


Why do planes fly over the ocean instead of land?

There is less turbulence over water than over land, because the primary cause of turbulence is hot air rising from the ground. Water distributes heat a lot better than soil, making flights over the ocean much smoother.


Why do planes fly so high?

The biggest reason for flying at higher altitudes lies in fuel efficiency. The thin air creates less drag on the aircraft, which means the plane can use less fuel in order to maintain speed. Less wind resistance, more power, less effort, so to speak.
