Department of Transportation "], "item_description" : "This project has three main objectives. The first objective isto model noise from complete aerobatic routines for a range of aircraft. The second isto compare modeledand previously measured aircraft noise from complete aerobatic routines for a range of aircraft. The third isto model the noise from up to 50 daily aerobatic routines for a range of aircraft. The end result ofthis analysis isa matrix of modeled noise results for a range of aircraft performing a variety of aerobatic routines. The FAA can now utilize these results to help set the technical threshold for approving NEPA analyses for aircraft performing aerobatic routine represented within the matrix.", "item_img_path" : "https://covers4.booksamillion.com/covers/bam/1/49/449/631/1494496313_b.jpg", "price_data" : { "retail_price" : "15.99", "online_price" : "15.99", "our_price" : "15.99", "club_price" : "15.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
