While NBAA and the General Aviation Manufacturers Association support the December 2004 implementation of domestic reduced vertical separation minimums (DRVSM) between FL 350 and 390, the two associations are adamantly opposed to expanding DRVSM to below FL 350 before December 2006. In a jointly signed letter to FAA Administrator Jane Garvey, NBAA and GAMA wrote, “Having to develop and publish required Service Bulletins and STCs, install the required equipment in more than 6,000 airframes and then have FSDOs verify their certification argues persuasively for a longer lead time.”
