Runway at a Glance
Arrival Volume
29 landings observed on Runway 30 in the last 30 days, alongside 19 departures.
Peak Hour
Busiest landing window observed at 14:00 with 14 arrivals on the recent sample.
Average Touchdown Zone
Aircraft touch down on average 2,164 ft from the threshold on Runway 30.
Prevailing Wind & Gust History
Over the past 365 days, winds at KNSI have prevailed from the west-northwest (300°), accounting for roughly 50% of windy observations. Average wind speed sits at 8.9 kt with peak gusts to 46 kt. Strong winds (≥20 kt) occur on about 6% of observations — pilots flying into runway 30 should plan for occasional gusty conditions.
Light Crosswind Component
Average crosswind on landing is 3.2 kt at touchdown, measured against runway 30 alignment.
Approach Slope
Final-approach slope averages 1.4° on Runway 30, shallower than the standard 3°.
Landing Behavior and Touchdown Performance
The metrics below are computed from ADS-B trace data observed at Runway 30 over the last 30 days. Each value is shown only when at least 10 valid samples were available; sparse cells are hidden rather than estimated.
Hourly Landing Distribution
Recent observed landings on Runway 30 grouped by hour-of-day (UTC).
Approach Types and Categories
Aircraft approach runways using different procedures based on weather conditions, visibility, and available navigation equipment. An Instrument Landing System (ILS) approach provides precision horizontal and vertical guidance using ground-based radio signals, enabling aircraft to land in low visibility conditions. Visual approaches require pilots to maintain visual contact with the runway and surrounding terrain, typically used during clear weather. Area Navigation (RNAV) approaches use GPS technology to guide aircraft along specific flight paths.
Approach Categories Explained
Category (CAT) classifications define minimum visibility and decision height requirements for instrument approaches. Higher categories enable operations in lower visibility conditions.
Wind and Environmental Factors
Wind conditions directly impact runway operations, influencing approach difficulty, landing performance, and runway selection. Runway 30 benefits from favorable wind alignment, with prevailing winds creating minimal crosswind components for most operations. Average wind speeds of 12 knots pose no operational constraints for commercial aircraft.
24-Hour Wind Pattern
Wind patterns show typical diurnal variation with stronger winds during midday hours.
