Unfortunately, RunwayFinder was recently shut down because of a patent that FlightPrep recently was awarded. Like many patents, the patent is not new and novel but was awarded none the less and they are currently bullying these small free online resources to pay outrageous fees or shut down.
It is the free innovative sites that make flying safe, fun and exciting. I would encourage you to let Flight Prep know if you are not happy with their current strategy as it most certainly harms general aviation and adds more costs.
Here is the contact info for FlightPrep:
Avweb and many other sites have been covering this if you want to read more about it.
I will also choose not to purchase any FlightPrep software or any other products associated with Flight Prep. I just don’t feel the actions they are taking are best for aviation. I don’t mind paying for products that are innovative and unfortunately, RunwayFinder was a better product at a free price. The aviation community is relatively small and our voices can be heard loud and clear.
