WHY DO THE JETS SEEM TO BE GETTING BIGGER AND LOUDER?
The sizes of corporate aircraft have actually not changed a great deal in the last 15 years but fortunately they have become quieter. The newer business jets are the most technologically advanced and quietest aircraft around. It is the slightly smaller, much older jet aircraft that are the noisiest. In December 1999, the FAA completed the phase out of the majority of the older/louder jet aircraft that weigh more than 75,000 lbs. Unfortunately, no phase out is required for aircraft weighing less than 75,000 lbs. that serve general aviation airports such as MMU.
