Aviation industry data provider Conklin & de Decker is celebrating its 30th year in business, and in honor of that milestone is offering special discounts on its products here at Heli-Expo. During the three days of the show, attendees visiting the company’s booth (No. 3002) can see live demonstrations of the company’s family of helicopter operating cost programs and life cycle budgeting tools. Buyers will receive a 10-percent discount off the price of the company’s most popular data products, including the Aircraft Cost Evaluator, the Life Cycle Cost, the Aircraft Performance Comparato, and its recently released Tax Guide for General Aviation. The last contains the latest taxes and fees imposed on general aviation in all 50 states, and it also addresses the sales and use taxes applicable to aircraft sales, ownership, leases, parts and labor. As many states continue to find ways to “enhance their revenues,” the guide will provide subscribers with continuous downloadable updates throughout the year through the Conklin & de Decker website.
