In late May at the EBACE show in Geneva, Dassault unveiled a new version of the Falcon 900. Dubbed the Falcon 900DX, the trijet is a clone of the 900EX, except for its fuel tanks. Dassault salespeople, however, can arguably talk about value for money–the 900DX’s price is hardly higher than that of the 900C it replaces ($31.95 million versus $31.6 million).

The advent of very light jets has prompted an FAA proposal to require that all new certification projects for turbofan-powered airplanes of 6,000 pounds or less mtow undergo function and reliability testing similar to that which has been required for larger fanjet-powered airplanes. F&R testing would add complexity, time and cost to new-design projects. The new requirement would not apply to developmental projects already under way.
