JUL 08, 2005 (newstodate): After January 1, 2006, designs for commercial passenger or cargo aircraft with maximum take-off weights over 12,500lbs, about 5,700kg, submitted to the US FAA must be compliant with ICAO's latest Stage 4 noise standard.
The adoption of a new noise standard for new aircraft designs is however not intended to signal the start of any rulemaking or other proceeding aimed at phasing out the production or operation of current aircraft models, FAA says.
Currently, there are no Federal regulations restricting the operations of Stage 3 airplanes, and the FAA has made no decision whether to seek such restrictions.
The requirement ratifies a new noise standard proposed in December 2003 that are a cumulative 10 EPNdB (effective perceived noise level in decibels) below current Stage 3 limits.
