(i) The likelihood of any hazardous condition that may cause death or serious injury to the public must be extremely remote.
(ii) The likelihood of any hazardous condition that may cause major property damage to the public, major safety-critical system damage or reduced capability, a significant reduction in safety margins, or a significant increase in crew workload must be remote.
(i) Designing for minimum risk,
(ii) Incorporating safety devices,
(iii) Providing warning devices, or
(iv) Implementing procedures and training.
(i) Test data,
