WebAn airspeed indicator indicates the aircraft's speed relative to the air mass. The air mass may be moving over the ground due to wind, and therefore some additional means to provide position over the ground is required. This might be through navigation using landmarks, radio aided position location, inertial navigation system, or GPS. WebAnswer (1 of 3): In meteorology wind speeds are generally measured and formally reported in knots or meters per second. For communication of current or forecast conditions, the meteorologists may convert the value to miles per hour or kilometers per hour for consumption by the general public, dep...
