Yes there is a much better application for this than Excel. Microsoft Access!

If you're already a whiz at Excel, then you have a good start on building database tables. The next thing you need to learn is how to relate databases, write queries and reporting. Trust me on this, if you learn and use Access your program will be KILLER!

Furthermore, if you want to market this program, you can easily find a developer who can take your Access database and convert it to a compiled program fairly easily.

Yes, I'm sure AOPA and Sporty's has something that already does what you're putting together, but if you do it yourself what you'll end up with something that works exactly the way you want it. Free.

For instance, for my home based business I use Access to manage my accounting. Sure, I could use QuickBooks or PeachTree, but frankly those programs don't allow me to do any serious bookkeeping shenannigans. My home made accounting works the way I want it.

(are there any IRS agents who fly?)
