... 6 Detailed Analysis–Select Analysis Aircraft The goal of selecting specific aircraft for detailed analysis is to identify those aircraft that if modeled correctly (so that INM computed SEL equals measured SEL) , total sound energy for the GA fleet would be sufficiently close to the sound energy that would result if all evaluated aircraft could be correctly modeled.

Figure 5 Effect on total departure fleet sound energy of sequentially correcting each aircraft type, from highest contributor of energy to lowest contributor; the selection criterion is shown Table 7 Aircraft selected for detailed departure analysis, see Figure 5.

... Arrivals 6.3 Selection of the aircraft types most affecting arrival total energy was accomplished in a manner identical to the selection of departure aircraft, using arrival SEL values and operations numbers.
