flight instruments

In general, velocity is a speed (scalar magnitude) paired with a direction, and it's a vector:The speed of sound is a scalar. The velocity triangle is a vector sum.; But, in aviation, velocity and speed are sometimes used as synonyms. In this case, a "vertical speed indicator" and a "vertical velocity indicator" are the same instrument.
