Perhaps by "velocity" you're referring to the wind "vector," i.e., speed and direction. If so, the answer is simple: The wind speed alone is little help when calculating aircraft course. A pilot also needs to know the direction from which the wind is coming in order to accurately calculate intended course and speed.
Wind velocity is vector quantity. direction is also important.
The first American pilot to exceed the speed of sound in an airplane was Chuck Yeager.
We distinguish between speed and velocity because if you add the speedsof objects, their directions are important. For example, the velocity of an airplane with ...
velocity is speed and direction. It would not be good to be traveling at a speed of 500 mph in the wrong direction!
Mach 3.5 by SR-71.
That is it's maximum speed. Different for every aircraft.
what are important speed, velocity and acceleration in several sports
So that they can know what direction they're going, because velolocity includes direction!
Speed is the magnitude of velocity, with units of distance divided by time. An important distinction is that speed is a scalar and velocity is a vector. Consequently, speed (unlike velocity) does not have a direction.
... in order to add its velocity to his own, and in that way increase his ground speed. The advantage is only available when flying from west to east, and the technique is always more effective when an airplane is used.
Velocity is important when someone wants to know the DIRECTION as well as the speed of something. Velocity is a VECTOR value, which means that it has two parts to its magnitude: the direction as well as the speed. This can be important in many scenarios, such as when a rocket is launched..it is very important to know the direction/angle as well as the speed.
Wing plays an important role in the speed of an airplane. A headwind reduces the speed of the aircraft. A tailwind increases the speed of the aircraft.
