Engine cowls too are made from composites. Meeting Recap The February meeting of the Bay of Plenty Branch was held at the clubrooms of the Tauranga Gliding Club on the north west of Tauranga airfield. This was the same venue we had used for the Branch meeting and BBQ last year which was a great place for the AGM and accompanying lecture this year, titled: B787 Operations. The lecture was delivered by Owen Bieleski who holds an ATPL with military transport experience with the RNZAF before embarking on a commercial The extensive use of electric-based systems has career with major airlines overseas. Recently, he almost entirely replaced bleed-air and a good returned home with his family to Tauranga from number of hydraulic-based services.

Owen suggested with the extent of the changes to electrically-based systems, the B787 is sometimes called the ‘electric jet’. Owen explained the B787 is a very different design to its predecessors, with a heavy emphasis on electrical powered systems and multiple layers of automatically managed redundancy. Pilots are alerted to most failures via the EICAS (Engine Indicating and Crew Alerting System) as a Warning, Owen Bieleski showing an RNZAF F27 – Friendship at the start of his Caution or Advisory.

With extensive to know’ basis. airline experience on the B777, he is well qualified For passengers, too, Owen explained new features to discuss the features of the new Boeing 787 included lower cabin-altitude (to 6,000 feet) and wide-body ‘electric jet’. higher humidity levels to help reduce passenger While comparable in size to the B767-300, the fatigue on the long flights which the B787 is B787 is 35% lighter.

Two interchangeable VFSG’s are fitted on each engine and the APU, which together are capable of generating 1.4MW of electrical power. The aircraft has batteries and when all else fails a ram air turbine (RAT) provides essential power. Engine and electrically powered high pressure (5,000psi) hydraulics is used to power the primary flight control surfaces although some spoilers and the stabiliser are electrically actuated to provide system redundancy. The B787 cockpit with five multi-function displays (MFD’s) feature on the To conclude, Owen noted he had found the most with electronic flight bag (EFB) units to the side panel; new head-up displays (HUDs) are new which can be folded away. useful change on the B787 was the ergonomic inclusion of a rocker switch on the back of the While retaining the traditional control columns, all cockpit seats.

In answer to a later question about the retention of the traditional control column by Boeing in the 787, he thought it could be replaced by a side-stick control device at some stage. Engines used on the 787 include the GE GEnx-1B and Rolls Royce Trent 1000.

This will apparently require the removal of the centre-wing to comply with road transport rules in the UK.
