The Times of India reported last week in this story, that the FAA had grounded all Boeing 787 aircraft equipped with GEnx engines. This is not the case, and there were no Airworthiness Directives issued by the FAA nor any other regulatory actions in that regard.  Most of the world’s press got it right, but the flagship of Indian newspapers was unfortunately way off base. Today another story surfaced about an Air India 787 where the focus should be on Air India rather than the airplane.

Of course, even with this knowledge now public, TSA hasn’t changed procedures to require the side scans that could reveal weapons hidden on a body. What’s worse, the… Continue reading

Richard GoodheadThe Rolls-Royce Trent 7000 engine for the Airbus A330neo is an all new power plant, and will by the 7th variant in the Trent series.  We spoke with Richard Goodhead, Vice President of Customer Marketing, to obtain additional details about the new engine.

The Trent 7000 will offer the same thrust as the Trent 700, the leading engine on the A330ceo models, but will be a totally new design.  Based largely on architecture of the Trent 1000-TEN used on the Boeing 787, with additional technology from the Trent XWB used on the A350, the Trent 7000 will offer an 11% improvement in fuel burn per seat on the new aircraft.  Combined with aerodynamic and other improvements to the aircraft, the A330-neo will achieve a 12% reduction in trip fuel and a 14% reduction in fuel per seat.
