Licence conditions can be modified in two ways:

• using a statutory process to modify set out in the Civil Aviation Act 2012
• using a self-modification process in which GAL and its airline community can modify certain specified parts of its commitments

Any modifications to the licence will be shown on our public register with a link from this page.

GAL is obliged to produce an operational resilience plan under its licence. Documents relating to the requirement are below:

• Gatwick - additional guidance for operation resilience plans required under Condition C1 of the licence and Condition 7 of Gatwick Airport Conditions of Use (September 2014)
  
  
• Gatwick - consultation on additional guidance for operational resilience plans (July 2014)
  • response from Gatwick Airport
  • response from Gatwick ACC
    
    
• Review of operational resilience at Heathrow and Gatwick - report by Steer Davies Gleave (July 2014)

GAL pays rebates to airlines if its service quality does not reach specific standards. Details of its performance against the standards are on the Gatwick airport website.
