UK – EU Transition, and UK Civil Aviation Regulations

To access current UK civil aviation regulations, including AMC and GM, CAA regulatory documents, please use this link to UK Regulation. Please note, if you use information and guidance under the Headings below, the references to EU regulations or EU websites in our guidance will not be an accurate information or description of your obligations under UK law. These pages are undergoing reviews and updates.

The State Safety Board is presented with a dashboard based on the state safety objectives. The dashboard uses a traffic light system underpinned by a series of safety performance indicators (SPIs). This enables a dynamic approach to review and analyse the available data.

SPIs are based on the state safety objectives and focus on occurrences (quantitative) and contributing factors (qualitative). The SPIs are based on the available safety data including the sources detailed in the SSP inputs section. The SPIs are monitored and reviewed by the CAA safety analysis team to ensure they remain appropriate.

The safety performance indicators that are currently being assessed are:

  • Loss of control occurrences as a result of:
    • Weather
    • Human performance
    • Technical failure
  • Fire occurrences
  • Smoke and fumes occurrences
  • Ground handling occurrences:
    • Resulting in aircraft damage
    • Relating to loading errors
    • As a result of other ground services (cold weather, fuelling, etc.)
  • Occurrences relating to airborne conflict:
    • Traffic Collision Avoidance System Resolution Advisories (Where systems onboard the aircraft alert the crew to take action to avoid another aircraft)
    • Occurrences of ‘level bust’ (Where an aircraft descends below or climbs above their cleared level)
    • Airprox’ events
    • Airspace infringement events
  • Occurrences relating to controlled flight into terrain:
    • Terrain Avoidance and Warning System (TAWS) warnings e.g. ‘Terrain’
    • TAWS alerts e.g. ‘Bank Angle’
  • Runway incursions by:
    • Vehicles
    • Aircraft
    • People
  • Occurrences that could have resulted in a runway excursion as a result of:
    • Weather
    • Human performance
    • Technical failure
