- causes a safety hazard to occur; and/or
- produces an excessive increase in operator workload
Major - Category 2
means a fault condition or discrepancy within the any of the systems with respect to the requirements specified in the relevant system technical specification which:
- significantly degrades the Customers ability to provide Air Traffic Services (ATS) at normal air traffic loads leading to a declared reduction in airspace capacity; and/or
- significantly increases the likelihood of a safety hazard occurring; and/or
- significantly increases operator workload
Medium - Category 3
means a fault condition or discrepancy within the any of the systems with respect to the requirements specified in the relevant system technical specification which:
- marginally degrades the Customers ability to provide Air Traffic Services (ATS) at normal air traffic loads; and/or
- marginally increases the likelihood of a safety hazard occurring; and/or
