A Jersey businessman has convinced 206 UK airports to adopt a scheme he said could save pilots' lives.
Charles Strasser is behind a proposal which prevents airports charging landing fees for aircraft which are in difficulty.
Biggin Hill, on the outskirts of London, is the latest to sign up.
Before Mr Strasser came up with his scheme, pilots in trouble would have to decide between paying high fees or risk flying on to a cheaper airport.
Mr Strasser said that decision put pilots at risk of crashing.
Over the past 12 years, Mr Strasser, a pilot himself, has lobbied airport authorities across the country to ask them to waive charges for emergency landings.
Thanks to his efforts, only six have kept the charges; all RAF bases and most major airports have agreed to drop them.
Jersey was second to sign up, after Mr Strasser got Guernsey's agreement first.
