Runway at a Glance
Arrival Volume
4 landings observed on Runway 18 in the last 30 days, alongside 3 departures.
Limited Traffic Observed
SkyMeter has observed very few flights using Runway 18 in the last 30 days. Statistical breakdowns (go-around rate, crosswind averages) need more observations to be meaningful.
Peak Hour
Busiest landing window observed at 13:00 with 5 arrivals on the recent sample.
Average Touchdown Zone
Aircraft touch down on average 9,155 ft from the threshold on Runway 18.
Prevailing Wind & Gust History
Over the past 365 days, winds at KOLZ have prevailed from the west-northwest (300°), accounting for roughly 15% of windy observations. Average wind speed sits at 9.1 kt with peak gusts to 52 kt. Strong-wind days are infrequent here.
Light Crosswind Component
Average crosswind on landing is 3.2 kt at touchdown, measured against runway 18 alignment.
Approach Slope
Final-approach slope averages 4.2° on Runway 18, steeper than the standard 3°.
Landing Behavior and Touchdown Performance
The metrics below are computed from ADS-B trace data observed at Runway 18 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 18 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 18 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.
