Little Navmap creates logbook entries for each flight automatically when detecting a takeoff or landing. A logbook entry containing only departure is created on takeoff and finalized with destination and more information on landing.
Create Logbook entries has to be checked to enable this functionality.
Note that all times, fuel consumption and other values are measured between takeoff and landing since it is not reliably possible to detect the start and end of a flight.
You can speed up the flight or to warp to another position without breaking the logbook record.
Editing functionality in the logbook is similar to the userpoints editing ( Userpoint).
Use Reset all for a new Flight to be sure that the logbook flight detection is set up for a new flight.
The logbook entries will not be recorded between different sessions. Update the logbook entry manually if you have to exit the flight simulator or Little Navmap.
23.1. Logbook Files¶
Each logbook entry has a reference using the full path to the used flight plan and aircraft performance files. Keep in mind that these references naturally break if the files are moved or renamed.
Additionally, the flight plan file, the aircraft performance file and the flown track are directly inserted into logbook entry. These attachments can be saved as LNMPLN, LNMPERF or GPX files. The GPX attachment is also used to show the trail and flight plan preview when selecting logbook entries in the search result table.
See Little Navmap LNMPLN Format for information about the LNMPLN format.
The GPX trail contains coordinates, flown altitude and time as well as the flight plan with airport and navaid idents, coordinates and calculated altitude.
The flight plan file contains all plan information like procedures or remarks.
You can access and modify the referenced and attached files in the context menu of the search result table and edit dialog.
Unfinished flights will not have trail information and show only the departure airport.
23.2. Logbook Search¶
The functionality of the search filters and the result table is equal to the airport and navaid search. See Search for information about search filters and buttons.
A search field
Airport ICAO allows to search entries having either a matching destination or
Additional context menu items and buttons allow adding, editing, and deleting of logbook entries as well as saving or loading the attached flight plan or track.
One or more logbook entries are highlighted on the map with blue lines connecting departure and destination as well as the two airports once selected in the search result table.
The label at the connecting great circle line shows departure airport ident, destination airport ident and great circle distance. A tooltip is shown if hovering the mouse over the blue direct connection or flight plan preview lines.
Logbook details (route preview and trail) on the map are only shown if one single entry is selected in the logbook search result table. Selecting more than one entry shows only the direct connection lines if enabled.
Search for logbook entries with a max distance of zero if you like to remove invalid entries from interrupted flights or pattern work.
23.3. Add Logbook Entry¶
Allows to create a new log entry manually. The dialog layout and
functionality is the same as for editing logbook entries. The button
Reset clears all fields.
23.4. Edit Logbook Entry¶
The dialogs for editing and adding are equal and contain three tabs.
Most fields have a tooltip explaining the meaning, are optional and can be freely edited.
Reset undoes all manual changes and reverts all fields
back to the original state.
23.4.1. Tab Logbook Entry¶
Additional notes about some fields on this page:
- Departure and Destination: These are automatically resolved to an airport. Coordinates (not shown and not editable) are assigned to the departure or destination airport if found. The dialog will show the airport name and elevation if the airport ident can be resolved. Otherwise an error message is shown.
- Date and Time in Simulator UTC: Time set in the simulator on liftoff or touchdown. Always UTC.
- Real local Time: Real world time on liftoff or touchdown. Stored in your local time.
- Route Description: Flight Plan Route Description extracted from the flight plan.
- Flight plan file and Aircraft performance file: Used flight plan and performance files. These are only references which will turn invalid if the files are moved or renamed.
23.4.2. Tab Fuel and Weight¶
Block fuel and trip fuel are extracted from Tab Fuel Report.
Used fuel is the fuel consumption between liftoff and touchdown.
23.4.3. Tab Remarks¶
Free text input field which is also shown in the tooltip and the information window on tab
See Remarks for more information about using web links in this field.
23.4.4. Edit a single Logbook Entry¶
23.4.5. Edit multiple Logbook Entries¶
If more than one logbook entry was selected for editing, the edit dialog shows a column of checkboxes on the right side of available fields. Not all fields are available for bulk edit.
If checked, the field to the left is unlocked and any text entered will be assigned to the respective field in all selected logbook entry. Unchecked fields will not be altered for any of the selected entries.
In combination with the search function, this allows for bulk changes like fixing an invalid aircraft type.
23.5. Logbook Statistics¶
This dialog shows two tabs:
Overviewcontains a general report which can be copied as formatted text to the clipboard.
Grouped Querieshas a button on top which shows different reports in the table below. The content of the table can be copied as CSV to the clipboard.
Some simulators report a wrong departure and arrival time in rare cases which can result in negative flying time for some flights.
The logbook statistics ignore these invalid simulator time intervals.
Correct the simulator departure or arrival time manually if you find such cases.
23.6. Import and Export¶
The full logbook or selected logbook entries can be imported and exported to a CSV (comma separated value) text file which can be loaded in LibreOffice Calc or Microsoft Excel. All data can be exported and imported which allows to use this function for backup purposes.
See chapter CSV Data Format below for more information on the format.
23.7. X-Plane Import¶
Imports the X-Plane logbook file
.../X-Plane 11/Output/logbooks/X-Plane Pilot.txt into the Little
Navmap logbook database. Note that the X-Plane logbook format is
limited and does not provide enough information to fill all Little
Navmap logbook fields.
The imported logbook entries get remarks containing
Imported from X-Plane logbook X-Plane Pilot.txt which allows to
search for the imported entries. Use a pattern like
*Imported from X-Plane logbook X-Plane Pilot.txt* in the description
search field to look for all imported entries.
Available information in the X-Plane logbook:
- Date of flight
- Departure airport
- Destination airport
- Number of landings - added to description.
- Duration of flight
- Time spent flying cross-country, in IFR conditions and at night - added to description.
- Aircraft tail number
- Aircraft type
X-Plane logbook example:
I 1 Version 2 190917 EDDN ESNZ 4 0.8 0.0 0.0 0.0 C-STUB 727-100 2 190917 ESNZ ESNZ 0 0.1 0.0 0.0 0.0 C-STUB 727-100 2 190920 LSZR LSZR 0 0.2 0.0 0.0 0.0 SF34
Automatically converts all legacy log entries that were collected as
userpoints having type
Logbook. The conversion copies them to the
new logbook after showing an information dialog.
The conversion works best if field
Remarks in the userpoints was
not modified and if no entries were inserted manually.
The converted logbook entries are appended to the current logbook. The
original userpoint of type
Logbook are not deleted or modified.
The converted logbook entries get a description containing
Converted from userdata which allows to search for the imported
entries. Use a pattern like
*Converted from userdata* in the
description search field to search for all entries.
Not all values can be recovered but the original description from the userpoint is stored in the description of the new logbook entry.
A warning dialog is displayed after the conversion which shows any issues during conversion.
23.9. Database Backup Files¶
Little Navmap creates a full database backup on every start since undo functionality is not available for logbook entries.
You can also use the CSV export to create backups manually since CSV allows to export the full dataset.
See Logbook for information about database backup files.
23.10. CSV Data Format¶
English number format (dot
. as decimal separator) is used in import
and export to allow exchange of files on computers with different
language and locale settings.
Little Navmap uses UTF-8 encoding when reading and writing files. This is only relevant if you use special characters like umlauts, accents or others. Otherwise encoding does not matter.
If an application fails to load a CSV file exported by Little Navmap, use LibreOffice Calc, Microsoft Excel or any other spreadsheet software capable of reading and writing CSV files to adapt the exported file to the format expected by that application.
See Comma-separated values in the Wikipedia for detailed information on the format.
Altitudes are always feet and distances are always nautical miles in the exported CSV.
The first line of the CSV contains the field names if chosen for export.
