British Civil Airworthiness Requirements Section S “Small Light Aeroplanes” is a standard based upon the European light aircraft standard JAR-VLA. It is an unusual standard in that it is a UK administered standard that is still in routine use and development, not having been superseded by a Joint Airworthiness Requirement (JAR).
Section S applies to the artificially defined class of “Microlight Aircraft” (some of which are
also referred to as “SLAs”)
