"The Embraer ERJ 135 is a twin-engine commuter airliner produced by Brazilian aircraft manufacturer Embraer. It has a capacity of carrying 37 passengers. The ERJ 135 is based on the ERJ 145, with 95% parts commonality, but is 11.7 feet (3.6 m) shorter.
Embraer launched the ERJ-135 on September 16 1997. Just nine and a half months passed before first flight on July 4 1998 ).ERJ-135 is a fairly straightforward development of the 145.
Both 135 prototypes were converted from ERJ-145 prototypes, requiring little modification other than the removal of two fuselage plugs totaling 3.50m (11ft 6in) in length.135 also features a Honeywell Primus 1000 avionics suite with five large multifunction displays in the cockpit, a Sundstrand APU and three abreast seating in the main cabin.
Other changes compared with the -145 are minor. Both are powered by Rolls-Royce (Allison) AE-3007 turbofans but the ERJ-135's are de-rated by around 5%, achieved by a slight software change to the engines' FADEC system. The only other notable change is new valves in the air-conditioning system.
135 is offered in standard ERJ-135ER and extended range ERJ-135LR forms. The LR features an additional fuel tank and slightly more powerful AE-3007A4 turbofans.
In September 1999 Embraer launched the third member of its regional jet family, the 44 seat ERJ-140.
