This document contains Minimum Operational Performance Standards (MOPS) for the Unmanned Aircraft Systems (UAS) Command and Control (C2) Data Link hereinafter in this document referred to as the Control and Non-Payload Communication (CNPC) Link System used to support the Command and Control functions of a UAS. The words "Non-Payload Communications" includes the CNPC Link System supporting remote pilot-to/from-ATC voice communications, also referred to as ATC relay. Payload communications specifically include communications associated with the UA mission payloads, which do not contain safety-of-flight information1. Therefore, payload communications do not require the use of aviation safety protected spectrum2 and are thus prohibited from using the CNPC Link System as described in this MOPS.
