PEA and AI spawn! (Probably)

Yeah the A310 is a A300 variant!

The Airbus A300 is Airbus' first production aircraft and the world's first twin-engine, double-aisle (wide-body) airliner. It was developed by Airbus Industrie GIE, now merged into Airbus SE, and manufactured from 1971 to 2007.
In September 1967, aircraft manufacturers in France, West Germany and the United Kingdom signed an initial memorandum of understanding to collaborate to develop an innovative large airliner. The French and West Germans reached a firm agreement on 29 May 1969, after the British withdrew from the project on 10 April 1969. A new collaborative aerospace company, Airbus Industrie GIE, was formally created on 18 December 1970 to develop and produce it. The A300 prototype first flew on 28 October 1972.

The first twin-engine widebody airliner, the A300 typically seats 247 passengers in two classes over a range of 5,375 to 7,500 km (2,900 to 4,050 nmi; 3,340 to 4,660 mi). Initial variants are powered by General Electric CF6-50 or Pratt & Whitney JT9D turbofans and have a three-crew flight deck. The improved A300-600 has a two-crew cockpit and updated CF6-80C2 or PW4000 engines; it made its first flight on 8 July 1983 and entered service later that year. The A300 is the basis of the smaller A310 (first flown in 1982) and was adapted in a freighter version. Its cross section was retained for the larger four-engined A340 (1991) and the larger twin-engined A330 (1992). It is also the basis for the oversize Beluga transport (1994). Unlike most Airbus products, it has a yoke, not using a fly-by-wire system.

Launch customer Air France introduced the type on 23 May 1974. After limited demand initially, sales took off as the type was proven in early service, beginning three decades of steady orders. It has a similar capacity to the Boeing 767-300, introduced in 1986, but lacked the 767-300ER range. During the 1990s, the A300 became popular with cargo aircraft operators, as both passenger airliner conversions and as original builds. Production ceased in July 2007 after 561 deliveries. As of September 2023, there are 197 A300 family aircraft still in commercial service.

A300-B10 (A310)

Airbus had demand for an aircraft smaller than the A300. On 7 July 1978, the A310 (initially the A300B10) was launched with orders from Swissair and Lufthansa. On 3 April 1982, the first prototype conducted its maiden flight and it received its type certification on 11 March 1983.

Keeping the same eight-abreast cross-section, the A310 is 6.95 m (22.8 ft) shorter than the initial A300 variants, and has a smaller 219 m2 (2,360 sq ft) wing, down from 260 m2 (2,800 sq ft). The A310 introduced a two-crew glass cockpit, later adopted for the A300-600 with a common type rating. It was powered by the same GE CF6-80 or Pratt & Whitney JT9D then PW4000 turbofans. It can seat 220 passengers in two classes, or 240 in all-economy, and can fly up to 5,150 nmi (9,540 km; 5,930 mi). It has overwing exits between the two main front and rear door pairs.

In April 1983, the aircraft entered revenue service with Swissair and competed with the Boeing 767–200, introduced six months before. Its longer range and ETOPS regulations allowed it to be operated on transatlantic flights. Until the last delivery in June 1998, 255 aircraft were produced, as it was succeeded by the larger Airbus A330-200. It has cargo aircraft versions, and was derived into the Airbus A310 MRTT military tanker/transport.
