FAA Issues RVSM Rule

In late October, the FAA issued its long-anticipated Final RuleonDomestic Reduced Vertical Separation Minimums (DRVSM) decreeing that on January 20, 2005, the required vertical separation between aircraft above the U.S. at altitudes from 29,000 to 41,000 feet will be reduced from 2,000 feet to 1,000. That means more available routes, which the FAA says will result in greater separation between aircraft. It also means that aircraft that fly at those altitudes must have more-accurate altimeters and enhanced autopilot systems.

In late October, the FAA issued its long-anticipated Final RuleonDomestic Reduced Vertical Separation Minimums (DRVSM) decreeing that on January 20, 2005, the required vertical separation between aircraft above the U.S. at altitudes from 29,000 to 41,000 feet will be reduced from 2,000 feet to 1,000.

It also means that aircraft that fly at those altitudes must have more-accurate altimeters and enhanced autopilot systems. Those upgrades are costly, and the National Air Transportation Association (NATA) was quick to announce it was "disappointed" in the rule. NATA complained in a news release on Thursday that the FAA failed to take into account the impact on small charter operators who can't afford the required equipment. The FAA said the upgrades will cost $800 million, but the more-efficient routing will save $5.3 billion in fuel costs by 2016. "Implementing RVSM is an important initiative within the FAA's strategic five-year Flight Plan to increase capacity," FAA Administrator Marion Blakey said in a news release Wednesday. "RVSM aids the agency's goal to improve global aviation harmonization." NATA, however, finds that harmonization a bit jarring. "We remain concerned that the FAA has not yet met the spirit or letter of their obligations to the regulated parties, in particular small Part 135 on-demand certificate holders," NATA President James Coyne said. The wait until 2005 gives operators time to install the upgrades, the FAA said. About 3,900 aircraft, or 44 percent of those affected, have already been made compliant, leaving about 4,900 yet to be modified and tested, according to an FAA estimate. Canada, South America, and the Caribbean countries will implement similar rules at the same time as the U.S.
