New air guidance system threatened with delays

The Washington Post reports on NextGen:

New air guidance system threatened with delays : "Now the Obama administration has embarked on the single most ambitious and expensive national transportation project since completion of the interstate highway system: a program called the Next Generation Air Transportation System (NextGen).

The NextGen concept sounds simple: Replace an air traffic system based on 60-year-old radar with a satellite-based Global Positioning System (GPS) network that would be far more versatile and efficient. In reality, it is an extraordinarily complex undertaking, threatened with delay by airline fears that the government will not deliver the system in time to justify their expenditures.

NextGen demands the largest investment ever made in civil aviation: between $29 billion and $42 billion for equipment, software and training by 2025. The cost would be shared by a federal government struggling with budget constraints and an airline industry that has been drained by years of recession and high fuel prices. Those tensions over funding threaten to slow the launch of NextGen, despite near-universal support for the program, and delays could prove costly."
