UK Civil Aviation Regulations

These are published by the CAA on our UK Regulations pages. EU Regulations and EASA Access Guides published by EASA no longer apply in the UK. Our website and publications are being reviewed to update all references. Any references to EU law and EASA Access guides should be disregarded and where applicable the equivalent UK versions referred to instead.



The Acceptable Level of Safety Performance (ALoSP) defines how safe a State wants their aviation system to be.

The UK ALoSP also sets the safety standards for the UK to have the trust and confidence of those encountering that system.

Aviation is generally regarded as one of the safest modes of transportation. When assessing aviation safety performance across the UK, we recognise that different safety standards are acceptable in different aviation sectors. The intent is that, through State oversight, the safety performance of each sector will continue to inspire trust and confidence in UK aviation.

The UK’s ALoSP

“No accidents involving commercial air transport that result in serious injuries or fatalities. No serious injuries or fatalities to third parties as a result of aviation activities.”

The UK aims to achieve this ALoSP through State safety objectives that:

  • Protect people from aviation safety risks.
  • Reinforce the UK position as a global leader in aviation safety.
  • Positively influence aviation safety through collaborative working with our international partners.
