Hi,I have questions on how to delete obsolete airports, modify airport's coordinations, or update navaid data, such as frequencies? The real-world Hobby (HUB) frequency is 117.10. Also, KIAH now has 15R ILS, not 15L ILS. I found some coordinations for some airports were not correct. Thank you very much for your time and help.Regards,Eddy

Eddy,These types of changes require editing the database. I would recommend Vol!Edit and DexImport as being essential tools to begin database-editing. Download the latest versions from the file library. Ironically, I've been working on releasing a tutorial on this, but my job keeps intervening. :-)For right now, I would check out the Database Minitutorials at the top of the Developers forum.Also, a basic DB-editing by Colin and myself is posted here on Salty's site: http://www.thesalters.org/fly2/database_editing_tutorial.htmHere's a basic ILS-editing tutorial by Harald Kraft that will also give you great info: http://ftp.avsim.com/library/sendfile.php?DownloadID=14441

Randall,Thanks again for your response. Please let me know when your tutorial is available.Eddy
