The B727 short to medium range airliner pioneered the rear trijet configuration. It has the redundancy of three engines, better climb performance than twin-jets, no ETOPS certification requirements, and improved operating economics over four engine jets. The 727 also introduced an advanced wing design, the triple slotted Krueger flaps, and the first on-board boeing APU (auxiliary power unit).
Boeing test flew the B727-100 in 1963 and production of the 727-100 ceased in 1973 but one recent notable development was Dee Howard in the USA upgrading a number of 727-100 freighters for express freight operator UPS. The major feature of the upgrade was reengining with RollsRoyce Tays, which improves performance, reduces fuel consumption and more importantly, allows the aircraft to meet Stage 3 noise requirements.
