In plain language

Your drone's flight control system must keep the aircraft within safe flight limits, allow you to take manual control at any time (unless the connection is completely lost), run self-tests, and verify any incoming data before using it.

Requirement as structured

CAAS states that the Flight Control System must include maneuver limits, allow pilot intervention at any time (except during total data link loss), feature a comprehensive self-test, and verify the integrity of external data before use.

Original regulatory text

The Flight Control System should satisfy the following capabilities: i) Contain maneuver limits to keep the UA in the flight envelope protection; ii) Except in case of total loss of data link, the UA pilot should have the opportunity to intervene at any time during the flight to ensure safe operations of the UA; iii) Designed and adjusted so that, within the range of adjustment (if any) available to UA pilot, no unsafe condition should arise; iv) Have a comprehensive self-test available and operating during all phases of flight, including during pre-flight; and v) Data exchanged between components of the flight control system or received from components external to the flight control system should be verified for the integrity of the information prior to use.
