Share of takeoffs by runway, month by month

Takeoffs are detected from ADS-B by our receiver, with gaps filled from the ADSB.lol archive (most 2024–2025 takeoffs come from the archive; 2026 almost entirely from our receiver). Shares are of takeoffs assigned to a runway; tracks between two runway headings are left out. Faded months had fewer than 10 days of data; the dashed month is in progress.

If the wind decided (“wind”): each Runway 24 or 6 takeoff is matched to the nearest KPOU weather report (METAR). Where the wind had at least 3 knots of headwind along one of the two runways, the takeoff is moved to that runway. Calm, crosswind and no-weather takeoffs keep the runway they used, and 15/33 is unchanged. Calm→6 also sends every calm-wind takeoff (3 knots or less, or variable at 6 knots or less) to Runway 6. That is an upper bound: it ignores traffic flow, instrument approaches and the tower's own calm-wind runway. Wind analysis to 2026-10-16; see Runway Use vs Wind for the method.
