Department of Transportation Feder "], "item_description" : "Performance based navigation (PBN), an enabler for the Federal Aviation Administration's Next Generation Air Transportation System (NextGen), supports the design of more precise flight procedures. However, these new procedures can be visually complex, which may impact the usability of charts that depict the procedures. This study evaluated whether there are performance benefits from simplifying aeronautical charts by separating visually complex area navigation (RNAV) and required navigation performance (RNP) procedures onto different chart images. Forty-seven professional pilots who were qualified to operate with RNAV and RNP participated. They used high-fidelity current and modified charts to find specific information from RNAV (RNP) approach and RNAV Standard Instrument Departure (SID) chart images that were shown one at a time on a computer monitor. Response time and accuracy were recorded.", "item_img_path" : "https://covers2.booksamillion.com/covers/bam/1/49/449/682/1494496828_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" : "" } }
