Injury Severity Classification Threshold (AIS 4)

In plain language

The safety assessment uses the AIS 4 standard to classify severe injuries. If a failure can cause an AIS 4 or worse injury, the system must be redesigned or mitigated.

Requirement as structured

TCCA accepts that an injury classification equal to or worse than Abbreviated Injury Scale (AIS) 4 requires mitigation or redesign unless the failure probability is remote or less.
