Short 360


The Short 360 is a commuter aircraft that was built by Northern Irish manufacturer Short Brothers during the 1980s. The Short 360 seats up to 39 passengers and was introduced into service in November 1982. It is a larger version of the Short 330.

Development

During the 1970s the world's commuter airline market began to evolve from the 20-seat class to larger and more comfortable cabins. Short Brothers of Northern Ireland had created the Skyvan in 1962, followed by the related but larger Short 330 in 1974.
The Short 360 development was announced in 1980, with the prototype's first flight on 1 June 1981 and type certification awarded on 3 September 1981.
The first production Short 360 had its maiden flight on 19 August 1982 and entered service with Suburban Airlines in November 1982.
After initiating production with the basic model, Short marketed a number of 360 developments. First was the 360 Advanced, in late 1985, with 1,424 shp PT6A-65-AR engines. That was followed by the 360/300, in March 1987, with six-blade propellers, more powerful PT6A-67R engines, and aerodynamic improvements, giving a higher cruise speed and improved "hot and high" performance. The 360/300 was also built in 360/300F freighter configuration.
Production of the 360 ceased in 1991 after 165 deliveries.

Design

The Short 360 is a 36-seat derivative of the 30–33 seat Short 330. In high density configuration, 39 passengers could be carried. The two Short airliners have a high degree of commonality and are very close in overall dimensions. The later 360 is easily identified by a larger, swept tail unit mounted on a revised rear fuselage. The 360 has a 3'0" fuselage "plug" which gave sufficient additional length for two more seat rows, while the extra length smoothed out the aerodynamic profile and reduced drag. Seating is arranged with two seats on the starboard side of the cabin and one seat on the port side. The 360's power is supplied by two Pratt & Whitney PT6A-65Rs.
Building on the strengths and reputation of its 330 antecedent, the 360s found a niche in regional airline use worldwide, being able to operate comfortably from 4,500 ft runways – opening up hundreds of airfields that would otherwise be inaccessible to airliners. With a cruise speed about 215 mph, at an altitude of 10,000 ft, the unpressurized 360 was not the fastest turboprop in its market but it offered acceptable performance at a reasonable price combined with ease of service and maintainability. The PT6A turboprops are fully ICAO Stage 3 noise-compliant, making the 360 one of the quietest turboprop aircraft operating today.

Variants

In 1998, approximately 110 360s were in service. In 2017 there were 42 Short 360 in service: 17 with Air Cargo Carriers, 6 with TransAir, 4 with Skyway Enterprises, 3 with Air Flamenco, 2 with Benair, Deraya Air Taxi and Freedom Air, 1 with Ayit Aviation, Comeravia, Gryphon Airlines, International Trans Air Business, Malu Aviation and Nightexpress. The Short 360 specifically proved very popular with the UK's regional airlines including the Isle of Man-based-Manx. This fed passengers into larger hubs in England, Scotland and Ireland.
Current and previous operators have included:

Civil operators

A number of small air cargo airlines have also operated the Short 360 in freight operations in the U.S.

Military operators

The Short 360 has been involved in 15 hull-loss accidents, resulting in the loss of 16 airframes.
