Runway 18R at YPEA
Runway 18R/36L at RAAF Base Pearce (YPEA) in Bullsbrook is a 5,712 ft, unlit, asphalt runway oriented 173°/353°. The runway is 98 ft wide. SkyMeter has observed 4 landings and 72 departures on this runway over the last 30 days, with approximately 0.0% of arrivals resulting in a go-around. Trace data shows an average final-approach slope of 1.8°, touchdowns averaging 386 ft past the threshold, a typical touchdown ground speed of 103 kt, a 7.5 kt average crosswind component, a 5.1 kt average headwind.

Runway at a Glance
Arrival Volume
4 landings observed on Runway 18R in the last 30 days, alongside 72 departures.
Limited Traffic Observed
SkyMeter has observed very few flights using Runway 18R 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 03:00 with 4 arrivals on the recent sample.
Average Touchdown Zone
Aircraft touch down on average 386 ft from the threshold on Runway 18R.
Prevailing Wind & Gust History
Over the past 365 days, winds at YPEA have prevailed from the east (90°), accounting for roughly 12% of windy observations. Average wind speed sits at 7.8 kt with peak gusts to 51 kt. Strong-wind days are infrequent here.
Moderate Crosswind Component
Average crosswind on landing is 7.5 kt at touchdown, measured against runway 18R alignment.
Approach Slope
Final-approach slope averages 1.8° on Runway 18R, shallower than the standard 3°.
Landing Behavior and Touchdown Performance
The metrics below are computed from ADS-B trace data observed at Runway 18R 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

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 18R 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.
