I was a user of RunwayFinder before I became a PnP Pilot. It is an easy way to plan a trip on a VFR sectional chart using a home computer. Dave Parsons, the brains behind RunwayFinder, posted on his blog today that due to several factors, he has decided to pull the plug on Runwayfinder effective the end of February. Both Skyvector and RunwayFinder are linked in our PnP bulletin board when we check on requests for flights. Skyvector will serve our purposes well, but some of us prefer RunwayFinder.
I won't go into all the messy background, but suffice it to say that a certain software developer claimed a patent infringement by Runwayfinder, and thus, due to the "sticky" hands of legal proceedings, RunwayFinder came out on the short end of the "stick." The shame of it is that the software developer that claimed a patent infringement does not offer a product that does near what RunwayFinder does. Oh well, that is progress, I suppose, in the USA, United States of Attorneys.
Have a good day!
