Electronic Aircraft Registers
I will always remember the months of March, April and May as the months all the new registration books were published. These also came with the knowledge that all the entries from the previous years had to be transfered across, hours and hours with the ruler and pen.
As the spotting increased so the annual transfer took longer and longer and hence I gave up in the end, happy with just the photography side of the hobby.
Enter the electronic age and computers for the spotter, this ten prompted the electronic registers. I have used "No More Underlining" for a number of years, I have upgraded from the basic version to world verion with lifetime updates - a very good deal.
Take a look at there website NMU for more information.
If you use a different programme I would love to publish a report on it, the more information we can give to our fellow spotters the better.
