Average crosswind on landing is 2.8 kt at touchdown, measured against runway 20 alignment.
Approach Slope
Final-approach slope averages 3.6° on Runway 20, steeper than the standard 3°.
Landing Behavior and Touchdown Performance
The metrics below are computed from ADS-B trace data observed at Runway 20 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 20 grouped by hour-of-day (UTC).
Go-Around Analysis
A go-around occurs when a pilot aborts a landing attempt and initiates a climb to return for another approach. While go-arounds are a normal safety procedure, their frequency and causes provide insight into operational challenges at specific runways. Runway 20 experienced go-arounds in 0.1% of arrivals over the last 30 days (1 events of 1660 attempts).
Recent Go-Around Events
These events represent normal safety procedures and do not indicate operational deficiencies.
Go-Around Causes Distribution
Environmental factors dominate go-around causes, indicating that operational procedures remain sound.
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 20 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.
