Definition
The two-part description of wind at a given location and altitude: the direction from which the wind is blowing (expressed in degrees relative to true or magnetic north) and its speed (expressed in knots). In flight, both must be considered together because each affects an airplane's track over the ground and its groundspeed during any maneuver.
Plain English
Which way the wind is coming from and how fast it is blowing. Pilots need both pieces of information together, because each one alone is not enough to predict how the wind will push the airplane.
Context Anchor
Used when planning and flying a steep spiral, especially while keeping the maneuver centered over a selected point on the ground.
Derivation
Velocity comes from the Latin idea of swiftness or speed. In aviation, it often points to more than just “fast” or “slow”; it also matters which way the moving air is coming from or going.
Why Pilots Care
Knowing the wind lets the pilot apply the right bank corrections so the spiral stays at the planned radius and descent rate instead of tightening or widening unexpectedly.
Grounding Statement
Picture circling over a road intersection while the wind keeps pushing the airplane away from it; knowing the wind direction and velocity tells the pilot how to correct that push.
Intuition Check
Wind direction does not mean where the wind is going; in aviation it normally means where the wind is coming from. Velocity is not just “strong wind”; it means the wind’s speed, with direction mattering for how it affects the airplane.
Example Sentence 1
Before beginning the steep spiral, the pilot noted the wind direction and velocity so they could increase bank on the downwind side and decrease it on the upwind side to keep a constant radius around the reference point.
Example Sentence 2
A shift in wind direction and velocity halfway through the spiral required an immediate increase in bank on the downwind side to hold the circle.
