Bjorn’s Corner: The challenges of airliner development. Part 3. Certification rules overview.
By Bjorn Fehrm, Henry Tam, and Andrew Telesca.
May 14, 2021, ©. Leeham News: The certification rules for different aeronautical vehicles are specific for each airworthiness jurisdiction. It means each country has its own rules for all the categories we listed in the last article. However, with the support of the International Civil Aviation Organization (ICAO), there is harmonization in many areas, especially around airport and airline operations. For airworthiness rules, most originated from dominant jurisdictions like the US FAA, whose rules have inspired the Canadian and European rules as well as many others.
As new technologies come to market, or new safety information is learned through testing, accidents, and incidents, the major regulatory agencies of the world constantly adapt with some rules harmonizing across jurisdictions and other rules diverging in different directions. It is an ever-evolving regulatory landscape that supports some of the safest transportation in the world, but it comes at a cost for companies as what was done in the past cannot always be expected to be accepted in the future, and the more global your desired market the more rules you need to understand and the more constraints your design will need to satisfy.
