The next stages will be to have a database which has a update/refresh proceadure and also allow the certain rows to be marked so they are not updated or refreshed, incase a customer is adding data manually that is not in our central database.
I think I shell be waiting until the above is complete before doing anything with my Navdata file, I have done a lot of manual updating of my database.
Even GAS don't have all the details of everything, I use a combination of GAS, Airframes etc etc to get all of my information.
Airnav - Can I just say (From the statment above), there is no way I am knocking what you are doing, you are moving things in the right direction - Thank you for that. I just find the combination of all the sites helps me.
