AI-friendly aircraft

How to make it operational:
Step 1: Download and save this aircraft to your collection

Step 2: Activate in-game AI air traffic in sandbox mode and wait patiently on the ground until the aircraft is spawned

If the aircraft is not spawning, remove decorative details such as lights, letters and numbers on the fuselage, then repeat the process again until the aircraft is spawned in your skies.

About the Aircraft: by Wikipedia

The Yakovlev Yak-40 (Russian: Yakovlev Yak-40; NATO reporting name: Codling) is a regional jet designed by Yakovlev. The trijet's maiden flight was in 1966, and it was in production from 1967 to 1981. Introduced in September 1968, the Yak-40 has been exported since 1970.

By the early 1960s, Soviet international and internal trunk routes were served by Aeroflot, the state airline, using jet or turboprop powered airliners, but their local services, many of which operated from grass airfields, were served by obsolete piston-engine aircraft such as the Ilyushin Il-12, Il-14 and Lisunov Li-2. Aeroflot wanted to replace these elderly airliners with a turbine-powered aircraft, with the Yakovlev design bureau being assigned to design it. High speed was not required, but it would have to be able to operate safely and reliably out of poorly equipped airports with short (less than 700 m or 2,300 ft) unpaved runways in poor weather.

Yakovlev studied both turboprop and jet-powered designs to meet the requirement, including Vertical Take-Off and Landing designs with lift jets in the fuselage or in wing-mounted pods, but eventually they settled on a straight-winged tri-jet carrying 20 to 25 passengers. The engines were to be the new AI-25 turbofan being developed by Ivchenko at Zaporozhye in Ukraine.

The Yak-40 is a low-winged cantilever monoplane with unswept wings, a large T-tail and a retractable tricycle landing gear. The passenger cabin is ahead of the wing, with the short rear fuselage carrying the three turbofan engines, with two engines mounted on short pylons on the side of the fuselage and a third engine in the rear fuselage, with air fed from a dorsal air-intake by an "S-duct", as is an auxiliary power unit, fitted to allow engine start-up without ground support on primitive airfields. The three AI-25 engines are two-shaft engines rated at 14.7 kN (3,300 lbf). The engines have no jetpipes, and initially no thrust reversers.

The pressurized fuselage has a diameter of 2.4 metres (94 in). Pilot and co-pilot sit side by side in the aircraft's flight deck, while the passenger cabin has a standard layout seating 24 to 27 passengers three-abreast, although 32 passengers can be carried by switching to four-abreast seating. Passengers enter the aircraft via a set of ventral airstairs in the rear fuselage.

The wing is fitted with large trailing-edge slotted flaps, but has no other high-lift devices, relying on the aircraft's low wing loading to give the required short-field take-off and landing performance. The wings join at the aircraft centerline, with the main spar running from wingtip to wingtip. The wings house integral fuel tanks with a capacity of 3,800 litres (1,000 US gal; 840 imp gal). The aircraft has a large fin, which is swept back at an angle of 50 degrees to move the tailplane rearwards to compensate for the short rear fuselage. The horizontal tailplane itself is unswept.

The Yak-40 was the first Soviet-built airliner designed to Western airworthiness requirements.

The first of five prototypes made its maiden flight on 21 October 1966, with production being launched at the Saratov Aviation Plant in 1967 and Soviet type certification granted in 1968. The type carried out its first passenger service for Aeroflot on 30 September 1968. In the 1972 version, a tailspin was removed. In 1974, new version was introduced, with non-stop flight distance increased. Also, the forward door on the right side of the fuselage changed its place – it was located together with the sixth window.

In 1975, the last upgrade of Yak-40 took place – the number of cabin windows on the right side changed from nine to eight.

By the time production ended in November 1981, the factory at Saratov had produced 1,011 or 1,013 aircraft. By 1993 Yak-40s operated by Aeroflot had carried 354 million passengers. As well as being the backbone of Aeroflot's local operations, flying to 276 domestic destinations in 1980, the Yak-40 was also an export success. In addition to this, Yak-40 became the first Russian/Soviet aircraft to get flying certificates from Italy and West Germany. It was demonstrated in 75 countries of the world, including the US, where orders for the Yak-40 were made.

A total of 130 were exported to Afghanistan, Angola, Bulgaria, Cambodia, Cuba, Czechoslovakia, Equatorial Guinea, Ethiopia, Germany, Guatemala, Honduras, Hungary, Italy, Laos, Madagascar, Philippines, Poland, Syria, Vietnam, Yugoslavia and Zambia.

As of July 2021, a Yak-40 has begun testing with an electric propeller engine in the nose of the aircraft.
