The purpose of this document is to define the Minimum
Interoperability Standards (MIS) for the uplink and downlink
message formats for Automated Meteorological Transmissions
(AUTOMET). This document also specifies a set of encoding and
decoding rules to apply to the message format types defined in this
document. AUTOMET message formats defined in this document are
independent of media and protocols used to transfer encoded AUTOMET
messages. AUTOMET operational requirements are not explicitly
specified.
This standard ensures AUTOMET-compliant air- and ground-based
systems will be able to decode and interpret AUTOMET uplink and
downlink messages. Compliance with this standard is recommended as
a means of assuring that avionics equipment implementing AUTOMET
software will perform their intended functions satisfactorily under
conditions normally encountered in routine aeronautical operations.
Regulatory application of this document is the responsibility of
appropriate governmental agencies.
