EMBRAER EMB-145 / ERJ-145
Embraer began working on a 50 seat short-haul feeder-liner jet concept in the late 1980s, revealed 12 June 1989, aimed at first flight late 1991 and first deliveries mid-1993. The programme was delayed by company cutbacks, complete redesign of wing and other changes, but this Embraer EMB145 was flown first on 11 August 1995. The original Embraer EMB145 concept used the straight-wings of the EMB-120 as well as a stretched version of the EMB-120 Brasilia fuselage. Later redesigns evolved to include swept wings with supercritical airfoils allowing improved performance. The engine location also moved from above the wings to below the wings and finally to the tail before the design was finally frozen.
The first flight was ahead of formal roll-out and "official" first flight a week later. The first of three preseries aircraft was flown on 17 November 1995, the second flew on 14 February and third 2 April 1996. The single prototype and three pre-series aircraft undertook a 1,600 hour, 13 month development flight testing and certification programme. FAA and Brazilian CTA certification was achieved 10 December 1996. Deliveries began on 19 December 1996 with two aircraft to US launch customer Continental Express.
The designation was changed from EMB-145 to ERJ-145 in October 1997 to reflect 'Regional Jet' terminology, although EMB-145 is retained for corporate and military variants.
It has a range of about 2500 km. Three basic versions of the ERJ145 were available: Extended Range (ER), Long Range (LR) and Extra Long Range (XR) versions.
By September 1998, the ERJ-145 was certified by the aviation authorities of 27 countries.
