scope:

This document provides manufacturers a set of guidelines in the design and development of an initial set of Cockpit Display of Traffic Information (CDTI) features. CDTI is the function of presenting surveillance information about the surrounding traffic to the flight crew. This guidance document is advisory in nature and its contents are expected to be a subset of the final CDTI MOPS. That MOPS, when published, will replace this document. In order to comply with certification standards, manufacturers will be required to demonstrate that 1) CDTI meets its intended functions, and 2) CDTI does not interfere with any other aircraft systems. This interim guidance provides a description of the intended functions of CDTI and as such may aid the certification process.
