Hi all, new user alert so be gentle if this sounds stupid. I am getting to grips with the database and how everything is refreshed and/or updated and have a query about how registrations are kept up to date. I had G-OHAJ recently going into EMA. On checking, this is not a current reg but i think should be G-TOYM (same frame but different reg). I am assuming from the previous posts that some form of database maintenance is essential? I have a database product that is well supported update wise so have a little faith i can use their lookup tool to get accurate code tie ups, but presume i need to be careful with the airnav database? Any further guidance on this subject would be appreciated.
