PROVISIONAL MESSAGE FORMATS AND PROTOCOLS FOR THE DABS 1PC/PWI DISPLAY

The document specifies provisional formats for the data link portion of the 'signals-in-space' which are part of the DABS interrogations and replies. Also included is a discussion of the characteristics that these signals assume while transmitted from the transponder proper to the instrument which delivers the messages to the pilot. Specifically, formats, algorithms, and protocols are assigned to serve the IPC (Intermittent Positive Control), PWI (Proximity Warning Indicator), and ATC (numerical indicator) functions. The protocol and algorithm for the pilot acknowledgment link is also included in this paper. (Author)
