scope:
Section 1 provides the text changes to Volume I. The change affects the "middle" aircraft of a multi-threat situation, and removes the feature that would have required a green arc to accompany that aircraft's RA.
Section 2 provides changes to the Pseudocode in Volume II, Attachment A. It clarifies the coding of certain bits reporting Hybrid Surveillance capability within the Data Link Capability Report, to be consistent with a change made to DO-300.
Section 3 provides changes to the state charts in Volume II.
Section 4 provides changes to the TSIM data set that is specified for the verification of the TCAS implementation. This material is not part of DO-185B, but is accompanying material distributed by FAA, not by RTCA
