FCC Equipment Authorization Application for the RTA-4218 RCPN 945-2185-001 Rev - Rockwell Collins Proprietary Information Page 41of 165 User’s Manual Rockwell Collins does not supply operating instructions with the RTA-4218. The RTA-4218 is designed to meet the requirements of ARINC 429 and 708A as well as RTCA documents DO-220, DO-160G, and DO- 178C. Rockwell Collins does produce a comprehensive installation manual which, pursuant to an agreement with the FCC staff, is available upon request but is not included in this electronic exhibit.
