Helicopter flight controls blades collectively ("i.e.," all at the same time) and independent of their position. Therefore, if a collective input is made, all the blades change equally, and as a result, the helicopter increases or decreases its total lift derived from the rotor. In level flight this would cause a climb or descent, while with the helicopter pitched forward an increase in total lift would produce an acceleration together with a given amount of ascent. The collective pitch control in a Boeing CH-47 Chinook is called a "thrust control", but serves the same purpose, except that it controls two rotor systems, applying
Chinook Jargon a hundred years old, like Henry Broderick, the realtor, and Joshua Green, the banker." Jones estimates that in pioneer times in the 1860s there were about 100,000 speakers of Chinook Jargon. Most books written in English still use the term Chinook Jargon, but some linguists working with the preservation of a creolized form of the language used in Grand Ronde, Oregon prefer the term "Chinuk Wawa" (with the spelling 'Chinuk' instead of 'Chinook').
