常见问题
What is a knot?+
A knot is one nautical mile per hour (1.852 km/h or 1.151 mph). It's the standard speed unit in aviation and maritime navigation because nautical miles correspond directly to degrees of latitude on the Earth.
What is Mach 1?+
Mach 1 is the speed of sound, approximately 767 mph (1,235 km/h) at sea level and 20°C. The exact value varies with altitude and temperature because sound travels slower in thinner, colder air.
