Maintenance items

Maintenance item

Set hours, months, or both (whichever comes first). Leave both blank for a one-time item such as a service bulletin.
Only used until the first sign-off. If it was already done, add a sign-off with the date and times instead.
Sets the next due by hand, for example to defer an item. Cleared automatically at the next sign-off, after which the normal interval applies again.

Sign off

Prefilled with current times. Change them if the work was done earlier.

Correct sign-off

The original values are kept in the correction history. If this entry is already in the paper journey log, you'll get a correction entry to write under it.

Journey log entry

Edit flight

Change an airport only if the automatic one is wrong; clear it to go back to automatic.
Set a known total (e.g. from your paper logs) on any flight; running totals count forward and back from it.
