In plain language

For medium-risk operations, the drone system must be designed so that the chance of a catastrophic failure is extremely low—specifically, no more than once in every one million flight hours.

Requirement as structured

CAAS states that for medium-risk BVLOS operations, the UAS should be designed to meet a safety objective where the probability of a catastrophic failure condition does not exceed 1x10-6 per flight hour.
