Details of how safety regulations will be tightened at UK air shows have been released following the Shoreham disaster.
Eleven men died when a Hawker Hunter jet crashed on to the A27 in West Sussex on August 22.
In its final report into the disaster, the Civil Aviation Authority (CAA) has:
- increased the minimum altitude ex-military jets can perform aerobatic manoeuvres
- increased the minimum distance of separation between a civil display and a crowd
- strengthened the requirements for post-display reports to improve feedback on safety issues
The regulator has already announced other measures such as enhanced risk assessments and tougher checks on the experience, skill and health of pilots.
All Hawker Hunter aircraft will remain grounded and ex-military jets stopped from performing aerobatics over land until an air accident report into what caused the crash is released.
The CAA plans on increasing event charges to cover the cost of implementing the new safety measures.
Dame Deirdre Hutton, chair of the CAA, said the changes would require "significant work" but were necessary to improve safety.
"We are already working with the air show community to make sure these measures are implemented for the upcoming display season and beyond, and so that the public has every confidence that UK air shows meet the highest safety standards."
