Development
Originally designated AS365 N4, the EC155 was developed from the Eurocopter AS365 N3 Dauphin 2 with the aim of significantly increasing the cabin space of the Dauphin. Development began in September 1996 with the helicopter officially announced by Eurocopter at the Paris Air Show in June 1997. The first EC155 helicopter, a modified Dauphin airframe, made its maiden flight at Marignane on 17 June 1997 and the first pre-production EC155 B flew on 11 March 1998. The aircraft received safety certification by the French & German Civil Aviation Authorities on 11 December 1998 and went into production soon after, with a price tag of US$7–8 million depending on installed equipment. Deliveries of the EC155 B began in March 1999, with the German Federal Police becoming the first operator.
The EC155 B1 was developed with more powerful engines and has improved performance at high altitude and in hot temperature conditions. This derivative also features a higher maximum take-off weight (10,846 lb vs. 10,580 lb). Deliveries of this model began in November 2002 with the Hong Kong Government Flying Service becoming the first operator.

Famous quotes containing the word development:
“Dissonance between family and school, therefore, is not only inevitable in a changing society; it also helps to make children more malleable and responsive to a changing world. By the same token, one could say that absolute homogeneity between family and school would reflect a static, authoritarian society and discourage creative, adaptive development in children.”
—Sara Lawrence Lightfoot (20th century)
“I hope I may claim in the present work to have made it probable that the laws of arithmetic are analytic judgments and consequently a priori. Arithmetic thus becomes simply a development of logic, and every proposition of arithmetic a law of logic, albeit a derivative one. To apply arithmetic in the physical sciences is to bring logic to bear on observed facts; calculation becomes deduction.”
—Gottlob Frege (1848–1925)
“To be sure, we have inherited abilities, but our development we owe to thousands of influences coming from the world around us from which we appropriate what we can and what is suitable to us.”
—Johann Wolfgang Von Goethe (1749–1832)
