Doubts are voiced over new aviation navigation system

Article Abstract:

The country's new satellite-based navigation system, which the Federal Aviation Administration hopes will improve its aging system of radio beacons and other navigation aids, has raised doubts among aviation experts. The new system, a centralized and enhanced version of the Global Positioning System, has the disadvantage of being vulnerable to system-wide problems. But the old equipment costs $100 million annually to maintain and its replacement over the next few years would cost billions. The new system, which will be fully operational by 2001, is scheduled for initial operations in about a year. A $475 million supplemental system backed by the FAA will provide annual savings of millions of dollars for airlines.

Autos' converters increase warming as they cut smog

Article Abstract:

The Environmental Protection Agency (EPA) has announced that catalytic converters have become a significant source of nitrous oxide, a greenhouse gas. According to the agency, a car with a fuel economy of about 10 miles a gallon would produce 0.27 grams of nitrous oxide per mile, or one-third the emissions for nitrogen oxide. The agency states that cars and trucks produce about half the amount of nitrous oxide, which represents about 7.2% of the gases causing global warming. Experts say that nitrous oxide is about 300 times stronger than carbon dioxide. The device itself, which breaks down compounds of nitrogen and oxygen from car exhaust, was devised to reduce smog.

Better Business Bureau says nuclear group ran false ads

Article Abstract:

The Better Business Bureau doesn't have any authority to do anything except cast its disparagement, this time on the nuclear power industry instead of on a product. The industry was found to have run false advertising by virtue of its claims: environmentally clean and makes power without polluting the environment. Since the bureau's National Advertising Division doesn't have any real powers, the nuclear industry can get away with saying that it will take the NAD's decision under advisement for its next campaign.
