I agree with the others. The GAS programme has it all - live updating (if you want) ability to update in your own time (if you want) and not having it connected does not affect data capture - by that I mean any internet downtime does not stop the sytem working. I regularly use it post outages to look for missing data etc.
Another area for the data - an EASY way to download to Access/Excel or others, that may also allow update of data from other systems. EG I have 10,600 aicraft logged in SBS1 and only 2000 in RB, to be able to use the data I have alrerady obtained for both systems would be great
