I had the opportunity to try the georeferenced airport diagram feature yesterday and it works great, except that there is about a 200+ foot error at KLZU, which could easily lead to confusion between two taxi ways. The error is exactly the same on my iFly and my friends brand "G" GPS. Is it the FAA or a third party that georeferences these diagrams? What is the best place / method to report such errors?

Thanks,

Dave

Dave,

Thanks for reporting this. We test the georeference data for airport diagrams against the published lat/lon end points of all the runways at an airport. I looked up KLZU and found the runway to be aligned perfectly. Then I looked at the airport in Google Earth and overlayed the airport diagram, and I see the errors in the taxi ways. So this is an error in the FAA published chart. I will report this to the FAA hopefully for future correction.

Thanks,
Walter
