Hackers may be able to access aircraft flight and management systems in Boeing's new mid-range jet, the 787-8, according to the US Federal Aviation Authority.
The FAA said that there are links between the networks that run the passenger "domain", which allows passengers to access the internet during flights, and aircraft-management systems. This means they do not contain "adequate or appropriate safety standards for protection and security of airplane systems and data networks against unauthorised access," the FAA said.
A Boeing spokesman said the aircraft maker was aware of the problem and would test its fix in March, when the so-called Dreamliner makes its maiden flight.
It delayed the first flight in September last year, and postponed deliveries by six months to the end of 2008. At the time it noted an "increasing risk to the delivery schedule", and said "the margin to accommodate unexpected issues had been eliminated".
