Meteorological Accessibility

Statistical analysis of historical weather data to determine operational minimums, evaluate runway accessibility, and optimise airport operations.

Meteorological Accessibility

A modern aerodrome is only as effective as its operational availability. At Altitude Nexus, we conduct high-fidelity meteorological accessibility studies, performing statistical analysis on decades of historical METAR/SPECI data to quantify runway usability and identify weather-related capacity constraints.

Runway Usability & Wind Coverage

We calculate the Usability Factor for each runway based on precise crosswind and tailwind components per aircraft type. Our automated analysis of historical weather reports generates detailed wind roses, ensuring your aerodrome meets the ICAO 95% usability requirement for safe operations.

  • Statistical METAR/SPECI Data Processing
  • Crosswind & Tailwind Limit Analysis
  • Multi-Runway Interaction Studies
  • ICAO Annex 14 & EASA Compliance

Visibility & RVR Frequency

We assess the frequency and duration of low-visibility conditions (LVP), analysing RVR and cloud ceiling data to provide technical evidence for CAT II/III ILS upgrades. Our studies help operators understand the cost-benefit of navigational aid investments based on actual weather statistics.

  • LVP Operations Assessment
  • Cloud Ceiling & Visibility Minima Determination
  • CAT II/III Investment Justification
  • Diversion Rate Probability Analysis

Meteorological Risk & Operational Delays

We quantify the impact of unfavorable meteorological conditions on airport slot capacity. By correlating weather patterns with operational data, we help aerodrome managers anticipate delays and optimize resource allocation during adverse weather events.

  • Weather-Related Delay Modelling
  • Operational Performance Benchmarking
  • Strategic Maintenance Planning Support
  • Aeronautical Information Publication (AIP) Data Support

Regulatory Framework

  • ICAO Annex 3 — Meteorological Service for International Air Navigation
  • ICAO Doc 9328 — Manual of RVR Observing and Reporting Practices
  • EASA AMC/GM to ADR.OPS — Aerodrome Operations
