Verified from official sourcesMG1Version 1Effective -Verified 31 August 2026
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.
