Boeing completes 737 MAX concept development phase

Boeing said in a statement that it has completed Firm Concept, a development phase that saw the aerospace company define the new single-aisle aircraft in broad terms.

‘The programme has achieved this development milestone by defining the significant changes needed to deliver the performance we’ve committed to our customers,’ said Beverly Wyse, vice-president and general manager of the 737 programme. ‘The team has a firm plan in place to incorporate all the changes necessary to realise a 13 per cent fuel-use reduction within the scope and schedule of the programme.’

Fuel-use reduction changes are said to include LEAP-1B engines from CFM International, a redesigned tail cone and Advanced Technology winglets. Other changes allow these fuel-saving features to be integrated into the overall aircraft design.

Boeing also decided to incorporate limited systems changes to the 737 MAX, including an electronic bleed air system that will be supplied by Honeywell and large-format displays, supplied by Rockwell Collins, for the flight deck.
