An aviation and meteorology term for wind moving slower than 3 knots — effectively no meaningful wind for flight purposes.
An aviation and meteorology term for wind moving slower than 3 knots — effectively no meaningful wind for flight purposes. When weather reports show calm wind, pilots know there's no crosswind to factor into their landing approach. The term is precise and technical; it's not just "not very windy" but a specific measured threshold. On ATIS broadcasts and METARs, calm wind is formally reported when wind speed falls below the threshold.
The ATIS report showed calm wind, making the approach straightforward for student pilots.
