Runway at a Glance

Arrival Volume

74 landings observed on Runway 27 in the last 30 days, alongside 63 departures.

Peak Hour

Busiest landing window observed at 08:00 with 15 arrivals on the recent sample.

Average Touchdown Zone

Aircraft touch down on average 1,359 ft from the threshold on Runway 27.

Prevailing Wind & Gust History

Over the past 365 days, winds at RJSY have prevailed from the west (270°), accounting for roughly 23% of windy observations. Average wind speed sits at 9.2 kt with peak gusts to 50 kt. Strong winds (≥20 kt) occur on about 5% of observations — pilots flying into runway 27 should plan for occasional gusty conditions.

Light Crosswind Component

Average crosswind on landing is 2.2 kt at touchdown, measured against runway 27 alignment.

Approach Slope

Final-approach slope averages 2.2° on Runway 27, shallower than the standard 3°.

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.

CAT I
Decision Height: 200 ft
Visibility: 550m
CAT II
Decision Height: 100 ft
Visibility: 300m
CAT III
Decision Height: 0-50 ft
Visibility: 0-200m
Visual
Clear of Clouds
Visibility: 5 km

Wind and Environmental Factors

Wind conditions directly impact runway operations, influencing approach difficulty, landing performance, and runway selection. Runway 27 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.
