RTCA DO-267

Description / Abstract: The revised MASPS removes the binary test data sets and establishes a publicly accessible FIS-B Product Registry that facilitates coordination and publication of specifications for Application Protocol Data Unit Payload encoding of new FIS products. The document contains the MASPS for FIS-B, an automated, digital data link system that provides timely access to data link updates of non-control, advisory information needed by pilots to operate safely and efficiently in the National Airspace System and in international airspace. It supports interoperability between providers of ground and airborne FIS processing systems by defining a broadcast protocol that may be used in any broadcast medium (i.e., VHF, satellite). The FIS-B broadcast June 2014 RTCA List of Available Documents Page 59 of 142 network organization consists of a physical layer, an International Standards Organization (ISO) standardbased Data Link Services (DLS) layer, a Network layer, a FIS-B Application Service Element (ASE), and a FIS-B Application. The physical layer is supplied by the manufacturer with all the other layers and/or elements defined in the MASPS.
