The Boeing 767 is a mid- to large-size, long-range, wide-body twin-engine jet airliner built by Boeing Commercial Airplanes. It was Boeing's first wide-body twinjet and its first airliner with a two-crew glass cockpit. The aircraft has two turbofan engines, a conventional tail, and, for reduced aerodynamic drag, a supercritical wing design. Designed as a smaller wide-body airliner than earlier aircraft such as the 747, the 767 has seating capacity for 181 to 375 people, and a design range of 3,850 to 6,385 nautical miles (7,130 to 11,825 km), depending on variant. Development of the 767 occurred in tandem with a narrow-body twinjet, the 757, resulting in shared design features which allow pilots to obtain a common type rating to operate both aircraft. The 767 is produced in three fuselage lengths. The original 767-200 entered service in 1982, followed by the 767-300 in 1986 and the 767-400ER, an extended-range (ER) variant, in 2000. The extended-range 767-200ER and 767-300ER models entered service in 1984 and 1988, respectively, while a production freighter version, the 767-300F, debuted in 1995. Conversion programs have modified passenger 767-200 and 767-300 series aircraft for cargo use, while military derivatives include the E-767 surveillance aircraft, the KC-767 and KC-46 aerial tankers, and VIP transports. Engines featured on the 767 include the General Electric CF6, Pratt & Whitney JT9D and PW4000, and Rolls-Royce RB211 turbofans. United Airlines first placed the 767 in commercial service in 1982. The aircraft was initially flown on domestic and transcontinental routes, during which it demonstrated the reliability of its twinjet design. In 1985, the 767 became the first twin-engined airliner to receive regulatory approval for extended overseas flights. The aircraft was then used to expand non-stop service on medium- to long-haul intercontinental routes. In 1986, Boeing initiated studies for a higher-capacity 767, ultimately leading to the development of the 777, a larger wide-body twinjet. In the 1990s, the 767 became the most frequently used airliner for transatlantic flights between North America and Europe. The 767 is the first twinjet wide-body type to reach 1,000 aircraft delivered. As of January 2016, Boeing has received 1,163 orders for the 767 from 74 customers; 1,083 have been delivered. A total of 765 of these aircraft were in service in July 2015; the most popular variant is the 767-300ER, with 583 delivered; Delta Air Lines is the largest operator, with 95 aircraft. Competitors have included the Airbus A300, A310, and A330-200, while a successor, the 787 Dreamliner, entered service in October 2011. The 767-200 was the original model and entered service with United Airlines in 1982. The type has been used primarily by mainline U.S. carriers for domestic routes between major hub centers such as Los Angeles to Washington. The 767-200 was the first aircraft to be used on transatlantic ETOPS flights, beginning with TWA on February 1, 1985 under 90-minute diversion rules. Deliveries for the variant totaled 128 aircraft. There were 49 passenger and freighter conversions of the model in commercial service as of July 2015. The type's competitors included the Airbus A300 and A310. The 767-200 ceased production in the late 1980s due to being superseded by the extended-range 767-200ER. Some early 767-200s were subsequently upgraded to extended-range specification. In 1998, Boeing began offering 767-200 conversions to 767-200SF (Special Freighter) specification for cargo use, and Israel Aerospace Industries has been licensed to perform cargo conversions since 2005. The conversion process entails the installation of a side cargo door, strengthened main deck floor, and added freight monitoring and safety equipment. The 767-200SF is positioned as a replacement for Douglas DC-8 freighters. Roman Tmetuchl International Airport (IATA: ROR, ICAO: PTRO, FAA LID: ROR) is the main airport of Palau. It is located near the former capital Koror, just north of Airai on Babelthuap (Babeldaob) island. The airport is 6 miles (4 km) from Koror and 15 miles (25 km) from Melekeok. A resolution adopted by the Senate of Palau in May 2006 renamed Palau International Airport as the Roman Tmetuchl International Airport, in honor of late local politician and businessman Roman Tmetuchl. It is also known as Babelthuap/Koror Airport or Airai Airport. The airport covers an area of 480 acres (190 ha) at an elevation of 176 feet (45 m) above mean sea level. It has one runway designated 9/27 with an asphalt and concrete surface measuring 7,200 by 150 feet (2,194 x 45 m). For the 12-month period ending December 13, 2004, the airport had 1,142 aircraft operations, an average of 95 per month: 78% scheduled commercial, 10% air taxi, 8% general aviation and 4% military.
