PilotWorkshops has purchased the assets of ZD Publishing, and its line of "pilot-friendly" GPS manuals, the company announced Wednesday. ZD Publishing's founder John Dittmer created the line of GPS manuals covering 21 Garmin and Bendix/King panel-mount and handheld GPS units. PilotWorkshops says Dittmer will continue to update the manuals and will add to the list of offerings in the future.
Prior to the takeover, PilotWorkshops.com had become the largest distributor for Dittmer's manuals. It will continue to offer them as downloads or physical copies. President Mark Robidoux said the manuals "focus on getting something done as opposed to the 'buttonology' focus in many manufacturer manuals," adding that his company has received "tremendous feedback" from customers familiar with the books. PilotWorkshops sells a range of products designed to improve pilot proficiency.
