Every ADS-B-tracked flight visualized in this print, captured over 2 days.

HND logged 2,552 flights across May 20–21, 2026, split almost evenly between 1,267 arrivals and 1,285 departures. Traffic ran continuously from midnight to 23:59 JST, averaging 53.2 flights per hour over the two days. The 8 o'clock hour carried the heaviest load at 177 total movements, with 86 arrivals and 91 departures. Activity stayed dense from 08:00 through 21:00, where most hours recorded between 124 and 177 flights. The overnight trough bottomed out at hour 3, with just 6 total movements, and the early morning hours from 04:00 to 06:00 skewed heavily toward arrivals before departures surged at 07:00. New Chitose (CTS) and Fukuoka (FUK) dominated the route list at 227 and 217 total movements respectively, accounting for roughly 17 percent of all traffic combined. Osaka Itami (ITM) ranked third at 118 movements. The remaining top-ten routes were all domestic Japanese airports, with totals ranging from 48 to 71 movements per pair. Approach and departure tracks both concentrated in the WSW quadrant, with WSW accounting for 496 arrivals and 506 departures. W and N were the next most common directions for both. A total of 508 unique aircraft were observed across the capture window, with Japanese-registered aircraft making up 350 of those. US-registered aircraft numbered 41, followed by China at 37. Altitude data spanned from ground level to a peak of 49,500 feet, with an average of 16,340 feet across all recorded ADS-B positions. The 0–1,000 foot band held the largest concentration of position points at 260,071, reflecting the volume of approach and departure traffic near the field. A secondary cluster appears in the 42,000–43,000 foot range at 39,997 points. Average groundspeed across all flights was 255 knots, with a maximum of 612.5 knots recorded. The longest flight in the dataset covered 1,818.5 nautical miles over 246.9 minutes, while the shortest departure tracked just 8.7 nautical miles over 28.9 minutes.
