Editing Airbus A319 (section)

===Origins and design===
The A319 design is a shortened fuselage, minimum change derivative of the A320 with its origins in the 130- to 140-seat SA1, part of the Single-Aisle studies.<ref name="N&W p.53">{{harvnb|Norris|Wagner|1999|p=53}}</ref> The SA1 was shelved as the consortium concentrated on its bigger siblings. After healthy sales of the A320/A321, Airbus re-focused on what was then known as the ''A320M-7'', meaning A320 ''minus seven fuselage frames''.<ref>{{harvnb|Eden|2008|p=26}}</ref> It would provide direct competition for the [[Boeing 737-300|737-300]]/[[Boeing 737 Next Generation|-700]].<ref name="N&W p.53"/> The shrink was achieved through the removal of four fuselage frames fore and three aft the wing, cutting the overall length by {{Convert|3.73|m|ftin}}.<ref name="A319 specifications"/><ref name="A320 specifications">{{cite web |title=Specifications Airbus A320 |url=http://www.airbus.com/aircraftfamilies/passengeraircraft/a320family/a320/specifications/ |url-status=dead |archive-url=https://web.archive.org/web/20120124123133/http://www.airbus.com/aircraftfamilies/passengeraircraft/a320family/a320/specifications/ |archive-date=24 January 2012 |access-date=13 February 2012 |work=Airbus}}</ref><ref name="Meeting demand">{{cite web |author=Moxon, Henley |date=30 August 1995 |title=Meeting demands |url=http://www.flightglobal.com/pdfarchive/view/1995/1995%20-%202575.html |url-status=dead |archive-url=https://web.archive.org/web/20120622033315/http://www.flightglobal.com/pdfarchive/view/1995/1995%20-%202575.html |archive-date=22 June 2012 |access-date=25 February 2011 |work=Flight International}}</ref> Consequently, the number of overwing exits was reduced from four to two. High-density A319s, such as 156-seat aircraft used by [[EasyJet]], retain four overwing exits.<ref>{{cite book|last=Beynon-Davis|first=Paul|title=eBusiness|year=2013|publisher=Palgrave Macmillan|page=341}}</ref> The bulk-cargo door was replaced by an aft container door, which can take in reduced height [[Unit Load Device|LD3-45 containers]].<ref name="Meeting demand"/> Minor software changes were made to accommodate the different handling characteristics; otherwise the aircraft is largely unchanged. Power is provided by the CFM56-5A or V2500-A5, derated to {{cvt|98|kN|lbf|lk=in}}, with option for {{cvt|105|kN|lbf}} thrust.<ref>{{cite web |author=Henley, Peter |title=A319 flight test |url=http://www.flightglobal.com/pdfarchive/view/1997/1997%20-%202909.html |url-status=dead |archive-url=https://web.archive.org/web/20120622054556/http://www.flightglobal.com/pdfarchive/view/1997/1997%20-%202909.html |archive-date=22 June 2012 |access-date=26 February 2011 |work=Flight International}}</ref>

With virtually the same fuel capacity as the A320-200 and fewer passengers, the range with 124 passengers in a two-class configuration extends to {{cvt|6,650|km|nmi}}, or {{cvt|6,850|km|nmi}} with the "Sharklets".<ref name="A319 specifications"/> The A319's wingspan is wider than the aircraft's overall length.
