81-662: While the official series name of the aircraft is Kunpeng , a mythical giant fish-bird from the Taoist classic Zhuangzi , it is nicknamed "Chubby Girl" ( Chinese : 胖妞 ; pinyin : Pàng niū ) in the Chinese aviation industry because its fuselage is much wider than aircraft previously developed in China. The Y-20 project began in July 2007. Images of the Y-20 prototype emerged at

162-575: A Part 91 Operator . These are the regulations that define the operation of small non-commercial aircraft within the United States , however, many other countries defer to these rules. These rules set conditions, such as weather, under which the aircraft may operate. This regulation states that the pilot-in-command is the party directly responsible for, and is the final authority as to, an aircraft being operated. Additionally, this regulation states that in an emergency requiring immediate action,

243-620: A Part 135 certificated airline (owned by the same parent company). This essentially allowed them to function as a scheduled air carrier (typically under Part 121 rules) while adhering to the less stringent Part 135 regulations. This enabled JSX to operate from fixed-based operator terminals, offering a more exclusive, private jet -like experience for their customers. Other air carriers, including Advanced Air , Contour Airlines and Southern Airways Express , have also adopted similar strategies using Part 380. This approach allows them to offer more economical service to smaller cities participating in

324-433: A comprehensive Chinese evaluation and certification system for aircraft composite materials based on international standards. Cargo is loaded through a large aft ramp that accommodates rolling stock. The Y-20 incorporates a shoulder wing , T-tail , rear cargo-loading assembly, and heavy-duty retractable landing gear, consisting of three rows, with a pair of wheels for each row, totaling six wheels for each side. According to

Additionally, Part 135 operators have lower TSA screening requirements for passengers. Part 135 operators may not sell individual seats on charter flights. Applicants for a Part 135 certificate must have exclusive use of at least one aircraft. Part 141 is a more structured method for pilot training, based on FAA syllabus and other standards. Part 21

567-512: A quote from the Tang zhi wen Ji (湯之問棘 "Questions of Tang to Ji", cf. Liezi chapter 5, Tang wen 湯問). The first account contrasts the giant Peng bird with a small tiao (蜩 "cicada") and jiu (鳩 "pigeon; turtledove") and the third with a yan (鴳 or 鷃 "quail"). The Peng fish-bird transformation is not only the beginning myth in Zhuangzi , but Robert Allinson claims, "the central myth". In

648-459: A revised Part 23 ruling went into effect, changing the aircraft classifications. The new passenger classifications are: Level 1, seating for 0 to 1 passenger; Level 2, 2 to 6; Level 3, 7 to 9; Level 4, 10 to 19. Speed classifications are: low speed, Vc or Vmo equal to or less than 250 knots CAS and equal to or less than Mmo 0.6 Mach; high speed, Vc or Vmo greater than 250 knots CAS and Mmo greater than 0.6 Mach.

The Buddhist monk Zhi Dun (314-366 CE) associated the Peng's flight with the highest satisfaction achieved by the zhiren (至人 "perfect person; sage; saint", cf. zhenren ). Now, that which wanders free and easy is clearly the mind of the Perfected Man. Master Chuang spoke of

2592-583: The FARs are designed to regulate certification of pilots, schools, or aircraft rather than the operation of airplanes. Once an airplane design is certified using some parts of these regulations, it is certified regardless of whether the regulations change in the future. For that reason, newer planes are certified using newer versions of the FARs, and in many aspects may be thus considered safer designs. The FARs have tens of thousands of separate sections, many used by large numbers of researchers on any given day. A few of

If a loss of radio communications were to be encountered during VFR conditions, or if VFR conditions are encountered after loss of communication with the ground and other aircraft, the pilot of the aircraft shall continue the flight under VFR and land as soon as practicable. If, however, the failure occurs in IFR conditions and/or

2754-495: The Peng is the image of the Daoist sage, and suggests the bird's flight does not result from the piling up of wind but from the deep piling up of de "virtue; power". In modern scholarship, some scholars reject Guo's "equality theory" construal. Lian differentiates contemporary interpretations between whether Zhuangzi was a radical skeptic and/or a relativist .

Allinson finds it "very clear and very explicit that the standpoint of the big bird and the standpoint of the cicada and the dove are not seen as possessing equal value." Karen Carr and Philip J. Ivanhoe find "positive ideals" in the Peng symbolizing the "mythical creature that rises above
