B787 - ETOPS fortsetter på 180 minutter

 Det høres snaut ut for flyging over Stillehavet. Det betyr at flyet ikke kan være lenger unna en alternativ landingsplass enn 3 timer mens den flyr på en motor. Det er imidlertid ikke uvanlig for et nytt fly med nye motorer. B777 som også har to motorer, er nå sertifisert for 330 minutter ETOPS. Norwegian, som skal fly til NY, Ft. Lauderdale og Bangkok vil ikke ha noen problemer.

Boeing and 787 operators around the world began installing modification kits in their Dreamliners last Friday after the U.S. Federal Aviation Administration approved the manufacturer’s proposed “fix” to their battery systems. Guidance for accomplishing the modification came in the form of an FAA-approved service bulletin, issued ahead of a “superseding” Advisory Directive due for publication in the Federal Register this week. Along with the approval of the battery adaptation, the FAA finished its review of the 787’s 180-minute ETOPs (extended twin-engine operations) clearance and opted not to reduce it, meaning the Dreamliner’s effective range on transpacific flights will not change.
