VLJ noise levels vs. FAA standards for jets. It is difficult to compare VLJ noise levels with those for piston and turboprops directly because the measurement standards are different for propeller aircraft. The measurements for pistons and turboprops are based on the A-weighted Sound Level (dBA), which also attempts to account for people's sensitivity to noise at different frequencies, but is much less complicated than the EPNdB calculation. In 2006, Eclipse Aviation published a study showing results from noise test- ing for the Eclipse 500 using the dBA standard. The results, shown in Figures 2-3 and 2-4, indi- cate that the Eclipse 500 is actually quieter on takeoff than other piston and turboprop aircraft, and within the same range on approach. These are very important findings and suggest that airport operators looking to bring VLJ traf- fic to their facilities can make strong arguments to address the concerns about jet noise that may arise. However, these graphs are not a substitute for a more extended noise analysis that may be used for FAR Part 150 noise compatibility planning or for FAA Order 1050 environmental assessments and environmental impact statements. Additional guidance on airport-specific noise planning is provided as part of the community outreach discussion in Chapter 6. 2.5 Other Attributes As shown in Figure 2-5, the range of VLJs is similar to other small aircraft. Although the reported ranges are similar between the different aircraft types, the range specification for piston aircraft is less stringent than for turboprops or jets. The piston values reflect the maxi- mum VFR range with all passenger seats occupied and a 30-minute fuel reserve. The turbine values reflect NBAA IFR estimates with all passenger seats occupied and sufficient fuel reserve for a 200-mile alternate.

Figure 2-5. Small GA aircraft range comparison. Figure 2-6 shows that VLJ aircraft are significantly faster than small GA piston or turboprop aircraft, although somewhat slower than larger aircraft in the light jet category. As shown in Figures 2-7 and 2-8, fuel burn rates and useable fuel capacities for VLJ aircraft are very comparable to those of small turboprops. From the viewpoint of an airport fixed base operator (FBO), this means that fuel sale opportunities are also likely to be similar.
