The Boeing 767-200ER (Extended Range) is a variant of the Boeing 767-200, a wide-body passenger aircraft designed for long-haul flights. Here’s the history of the 767-200ER:Origins and Development:The Boeing 767 was conceived as a wide-body aircraft to replace the 727 and 737 series on medium- and long-range routes. Boeing started developing the 767 in the early 1970s, aiming to provide greater capacity and fuel efficiency for airlines operating transcontinental and transatlantic flights.The 767-200 was the first model in the 767 family, entering service in 1982. With a seating capacity of around 181 passengers in a standard configuration, the 767-200 was ideal for longer-distance routes, but airlines soon began requesting versions with greater range to cover even longer routes.Introduction of the 767-200ER:The Boeing 767-200ER was introduced in 1984, two years after the 767-200, as a long-range version of the original aircraft. The "ER" in the name stands for "Extended Range," indicating that this variant was designed to operate on longer, more distant flights.The 767-200ER featured key modifications, including additional fuel tanks and more powerful engines, enabling it to operate transoceanic and intercontinental routes. This made it a direct competitor to other long-range aircraft like the Airbus A300 and the DC-10.Technical Features:Capacity: Depending on the airline’s configuration, the 767-200ER can carry between 181 and 224 passengers.Range: Its maximum range is about 7,000 nautical miles (13,000 km), allowing it to cover transatlantic and long-haul routes.Engines: It is typically equipped with Pratt & Whitney JT9D or CF6 engines, or the CF6-80C2 by General Electric, which provide the necessary thrust for longer flights.Configuration: The 767-200ER has a twin-aisle cabin and a variety of seating configurations for both economy and business classes.Use and Service:The 767-200ER became a popular choice for airlines that needed a longer-range aircraft but could
