Well, my system has been running a month now, and seems to work well. Although we had a long run in with a trial system, we still had a few problems when we went live. One was me, and the others were people not being very sensible. All sorted now, and our 120 members seem to find it very easy to use.
It isn't graphical in the same way as the open fliers one above, but is intended to mimic the "fill in the boxes" sheet we used before. Because it's written in Flash/PHP/MySQL it's much prettier than the sheets, and there's no Tippex or maths errors. It helps by showing the last Hobbs reading, and offering lists of destinations and flight types that can just be clicked on, rather that written. The club members who look after aircraft engine hours and finance have custom csv file downloads for the various parts of the database that they need, which speeds up and simplifies their tasks enormously. I must admit I'm quite proud of it. I'll wait a few months to see how it shapes up before I start work on version 2. Maybe v3.5 will turn commercial....
