# Logbook

Logbook stores personal flight records and supports exports for supported formats.

## <mark style="color:$warning;">Flight entries</mark>

A flight entry can include:

* Date.
* Origin and destination.
* Off-block and on-block times.
* Block duration.
* Aircraft type and registration.
* PIC.
* Role.
* Day and night takeoffs and landings.
* Night, IFR, dual received, and instructor time.
* Notes.

## <mark style="color:$warning;">Auto-fill behavior</mark>

When adding a flight, AvComp can auto-fill common values:

* Duration from departure and arrival times.
* IFR actual for jet aircraft where applicable.
* Night time based on night landing fields where applicable.

Review all auto-filled values before saving.

## <mark style="color:$warning;">Import and OFP pre-fill</mark>

Where available, Logbook can import or pre-fill flight details from OFP data to reduce manual entry. Imported data should be checked against the original record before saving.

## <mark style="color:$warning;">Exports</mark>

Supported export formats depend on the current app version. Use the export selector in Logbook to choose the available output format for your needs.

## <mark style="color:$warning;">Storage</mark>

Logbook data is stored locally in browser storage. Export important records regularly if you need a backup outside the device.
