Free FAA Pilot Logbook Application for logging flight time
JFlightLog is a free logbook application for pilots to record their flight hours.
All of the standard fields from the US FAA paper logbooks can be entered in JFlightLog. It is meant to backup and/or replace one's paper logbooks which can be the source of much drama when they become lost or covered with coffee.
The program can be downloaded from this site and then run on your local computer.
