Aircraft Shopper Online (ASO) and Conklin & de Decker have teamed up to offer aircraft cost and performance reports through the internet. Up-to-date information on over 50 models of piston-powered aircraft is available at www.ASO.com and can be paid for over the 'net using credit cards. Visitors to ASO's web site are able to purchase individual reports on piston-powered aircraft at a cost of $24.95 per report, with additional reports costing $14.95. Payment is by credit card.\r Conklin & de Decker's Aircraft Cost Evaluator for Pistons is assembled using data from the company's 'Aircraft Cost Evaluator' publication. On the site, interested buyers can view a sample report showing the five pages for each report, which show direct and variable costs, budgets, performance and specification data.\rASO believes that the web-based reports are in many ways superior to conventional printed reports. Explanations and details of each cost item and terms are available by simply clicking on the item itself, which pops up a small window containing a simple explanation. Reports can be printed and/or saved on the user's PC for later review. As a web site can be easily updated, it is claimed that the pages will contain the very latest version of the information.
