High Quality Content by WIKIPEDIA articles! ARINC 708 is a specification for airborne pulse doppler weather radar systems primarily found on commercial aircraft. ARINC 708 and the Honeywell Picture bus are the predominant avionics data bus for most aircraft today superseding ARINC 453.ARINC 708 uses a transformer-coupled Manchester encoded signal, like the MIL-STD-1553 protocol. Termination of the bus is essential for good signal quality. Furthermore, the bitstream is continuous, requiring good re-synchronization to the bit stream. Data frames are 1600 bits long with the header portion of the frame consisting of parameters such as range, tilt, gain, status, etc. The data portion is organized into 512 range-bins per scan angle value. Each range bin contains a color value to indicate the intensity at that position. Settings for the ARINC 708 system is typically controlled using an ARINC 429 interface.
