What kind of aircraft are the Embraer E-Jet family and the EMbraer J-Jet E2 family?
Embraer E-Jet E2 family The Embraer E-Jet E2 family is a family of three narrow-body medium-range twin-engine jet airliners developed by Brazilian aerospace company Embraer, replacing the predecessor Embraer E-Jet family. The three variants share the same fuselage cross sections with different lengths and three different new wings, Pratt & Whitney PW1000G geared turbofans in two sizes, fly-by-wire controls with new avionics, and an updated cabin with 40% enlarged baggage bins. Announced improvements per seat are 16 to 24% lower fuel burn and 15–25% lower maintenance cost.
Chengdu J-7 The Chengdu J-7 (Chinese: 歼-7; third generation export version F-7; NATO Code: Fishbed) is a People's Republic of China license-built version of the Soviet Mikoyan-Gurevich MiG-21. Though production ceased in 2013, it continues to serve, mostly as an interceptor, in several air forces, including the People's Liberation Army Air Force. The J-7 was extensively re-developed into the CAC/PAC JF-17 Thunder, which became a successor to the type.
