I have been thinking of writing something like this. It would be web based using PHP and MySQL database, including all the necessaries for FAA acceptable electronic signatures.
The data could be stored in a cloud or local.
But the system I was thinking of was for both pilot and plane. Say you make a flight. You enter that flight and the pertinent pieces go into pilot log, airframe log, engine log, squawks, etc. Reminders & many other things automated.
If the entry is maintenance only, then maintenance entries only. Paper certifications, documents scanned and stored, but also entered in the logs. Several printouts to paper available.
Would this come close?
