The SIGS module was initially created to serve a TC/ ICAO (International Civil Aviation Organization) obligation agreement to forward a copy of every Canadian published Airworthiness Directive (AD) and Canadian Airworthiness Civil Aviation Service Alert (CASA) to every ICAO member (250+ countries) when published.
The module was later modified to include various Sig_types, thus expanding the type of recipients beyond ICAO members, that can be contacted during the MDM process.
