Prevailing winds are changing and this is impacting airport runway usability. The value offered by this service is in providing an updated baseline of information that allows airport managers to quickly identify how prevailing winds have changed over a +10 year period and understand if their runways still meet the airport usability and safety regulatory recommendations of Transport Canada. This ensures that pilots have the greatest opportunity to operate aircraft within safe operating conditions at the airport.

Crosswind components of aircraft design groups and/or specific aircraft that are commonly and future operated at an airport are assessed in correlation with the meteorological analyses to ascertain the compliance conditions of airport usability of ≥ 95% and whether aircraft can safely operate on current and future runways as stipulated by Transport Canada, TP312 and CARs SOR/96-433.

This data is valuable to airport managers for ensuring safe operations at and around their airport by adhering to regulatory compliance and recommendations, supporting their Safety Management Systems (SMS), supporting airport master plans, applying and capturing Transport Canada funding, optimizing budgets for runway operations and maintenance, and driving new business and marketing opportunities.

Aero Polaris airport analytic services offer real value that is actionable and  user-friendly. Our deliverables allow airport managers to quickly and easily describe our findings and recommendations to other managers and personnel that do not have technical training. This is useful in scenarios involving multiple departments and agencies, which Aero Polaris has demonstrated with Transport Canada owned and operated airports. 


Our value proposition offers the following support to airport managers:

  • Ascertain airport usability of ≥ 95% as stipulated by Transport Canada and the FAA
  • Support Safety Management System (SMS) regime by identifying, analyzing, and reporting crosswind hazards to aviation safety and for evaluating and managing the associated risks of crosswind and taking corrective actions to prevent recurrence
  • Apply and win Transport Canada funding, such as ACAP by further improving safety and operational conditions at their aerodrome/airport
  • Support airport master plan developments
  • Optimize operations and maintenance budgets by decommissioning/developing runways
  • Address and mitigate against further accidents attributed to crosswinds as described by the TSB

Our deliverables consists of the following general structure:

  • Define airport usability requirements in accordance with regulatory agency (Transport Canada, FAA, etc.) standards and recommendations
  • Collect and analyze the historical meteorological conditions for the airport (Enviro Canada, NOAA, etc.)
  • Conduct a windrose analyses of prevailing wind speed, direction, and gust for seasonal hours of operations
  • Conduct aircraft crosswind component assessment in correlation with windrose analyses
  • Prepare a comprehensive report with recommendations

Sourcing national meteorological agencies (Environment Canada, National Oceanic & Atmospheric Administration), historical wind data is compiled from hourly and daily measurements of average and gust inputs. Data ranges of over twenty (+20), ten (10), and five (5) year intervals can be provided. Granular datasets analyzed over seasonal and historical periods provide airport managers with highly accurate and tailored assessments of changing prevailing winds and their impact on runway usability and operations and maintenance budgets. Significant cost-savings can be achieved if runway maintenance schedules are reduced or a runway is decommissioned.

Data inputs include meteorological files from Environment Canada, the National Oceanic & Atmospheric Administration, and etc. Analytic outputs include windrose charts representing customizable datasets that are visually represented on various maps (VFR, IFR, Google Maps), airport charts and diagrams (NAV Canada, FAA, and etc.), and in Google Earth files (.kml format). Analysis data output is also provided in Microsoft Excel spreadsheet files (.xlsx, .xls formats). 


Transport Canada airport funding and application to the Airports Capital Assistance Program (ACAP) and secondary crosswind runway projects are supported by our windrose analyses that involves analyzing wind data over 25 years and the seasonal usability of main runways, as well as the frequency of secondary crosswind runway use by regularly scheduled year-round passenger aircraft. Wind rose analysis is a mandatory prerequisite for ACAP eligibility criteria and receiving Transport Canada funding.

Our windrose analyses assist airport managers comply with the 2014 updated Federal Aviation Administration (FAA) AC 150/5300-13A - Airport Design. Airport managers will quickly and accurately understand how the direction and intensity of prevailing winds affecting their airport and runway orientation have changed over the decades and equip them with the data required to optimize airport operations and maintenance budgets to reflect this. Analyses are customizable to reflect seasonal and daylight operations. This proprietary software is licensed and requires specialized training direct from the manufacturer.
