Why do aircraft use knots?

Why knots? According to Scandinavian Traveler, the use of knots (kt) makes air and nautical navigation easier because it’s based on the nautical mile. The nautical mile is closely related to the longitude/latitude geographic coordinate system and is based on the circumference of the Earth.

Why are knots used at sea?

Boats & Planes calculate speed in knots because it is equal to one nautical mile. Nautical miles are used because they are equal to a specific distance measured around the Earth. Since the Earth is circular, the nautical mile allows for the curvature of the Earth and the distance that can be traveled in one minute.

How fast can a jet plane go?

The Lockheed SR-71 Blackbird is the fastest jet aircraft in the world, reaching speeds of Mach 3.3–that’s more than 3,500 kph (2,100 mph) and almost four times as fast as the average cruising speed of a commercial airliner. Key elements of the SR-71’s design made this possible.

Where do cruise ships fuel up?

There are over 400 marine ports in the world that provide fueling to cruise ships. Barges can come out to meet the cruise ship, or they will refuel the cruise ship while on port.

How much fuel is on a cruise ship?

In general, a large cruise ship up to 1,100 feet in length can carry as much as two million gallons of fuel on board. For comparison, a private motor yacht between 40 and 60 feet only carries 200 to 1,200 gallons, while something massive like the Exxon Valdez carries up to 55 million gallons.

What fuel does a cruise ship use?

The traditional cruise ships rely heavily on diesel (less than 0.1% sulfur) for their propulsion. The power system on board, including the generators and the boilers, also operate on this fuel.
