• Yes it does. AvionLog does automatic backups for first use of the day and last use of the day for the previous few days of use. This is so you can ‘unwind’ errors and mistakes while offline, say when you’re at work.

    Long-term backups to Box and DropBox are manually initiated.

  • Box and Dropbox are cloud storage providers independent from AvionLog. They are both reputable and well known companies. For more information see:

    No, you do not have to back up to both, but our terms assume you will use both services and we strongly encourage this.


    Many of AvionLog’s features borrow one of aviation’s strongest principles which all aviators are familiar with, system redundancy. Since your pilot logbook is so important we want to keep it as safe as possible so please use both Box and Dropbox.

  • Essentially yes. Box and Dropbox provide a certain amount of storage for free before asking you to pay. A typical experienced commercial pilot’s logbook when stored electronically is kilobytes of data rather than megabytes. This means you can store many historical versions of your logbook without cost and you can delete old backups. Of course if you use Box/Dropbox to store other files it may push you over the storage limit.

  • No they are not. Backups to Box and Dropbox are manually initiated. Mainly because you’re now pushing your data outside of AvionLog and we believe you should be in complete control of your data.

    To access the Box and Dropbox backup features, while online:

    1. Navigate to: Settings > Backup
    2. Ensure the toggle switches next to Box and Dropbox are turned on.

    From there a backup can be initiated at any time by clicking the 'Backup Now' button.

    1. Go to Settings > Backup.
    2. Make sure both Box and Dropbox toggle switches are on and ensure you have signed up to Box and Dropbox.
    3. Click ‘Backup Now’ button.

    Your logbook will be backed up to both services. Be sure to switch on backup reminders.

  • Yes you can and we encourage you to. You can copy your files outside Box/Dropbox to anywhere you’d like. Please make sure to keep a copy of your backup files in their current location within Box/Dropbox so they will remain accessible within AvionLog.

    1. Navigate to Settings > Backup > Backup Sets and Restore
    2. Click on the backup you wish to restore from.
    3. Click ‘Restore’ on the top right corner of the screen.
  • The time of backup is filed in UTC (Zulu) time.

  • Find the logbook file you want to delete, swipe left on that file and click delete. This will delete the file from Box/Dropbox.

Flight Logging

  • If not already on it, click on the ‘Flights’ icon on the bottom navigation bar then click the ‘+’ button at the top right corner of the screen.

  • The flight number feature will to pre-fill departure and destination airfields based on the last use of that flight number. The flight number can be in any alpha-numeric format.

    This feature is controlled at: Settings > Display > General - scroll to the bottom and enable the toggle switch for ‘Flight Number Recognition’.

  • The return flight feature speeds up a flight that returns to your original point of departure. It is accessed by clicking on the ‘fast forward’ button at the top right of the screen after you’ve logged the outbound flight. AvionLog will create a new flight on the same date as landing, swap your departure and destinations airfields, and pre-fill the aircraft and pilots names. It will also toggle the ‘Is pilot flying’ switch (if you’re using it). All you have to do is enter the flight times and your flight is logged.

  • Like the return flight feature detailed above, the next flight feature pre-fills as much information as possible based on your previous flight but leaving your destination airfield for you to define. The next flight feature is designed for an onward leg rather than a return flight.

  • The fastest way to enter an airfield is using an ICAO (4 letter) or IATA (3 letter) code. You can also ‘search’ by airfield name. For regularly used airports, making an airfield a favorite will make that airport appear at the top drop down menu when you click on an entry field.

  • There’s a lot of detail you can store when creating a new person in your logbook. You can search for people you’ve flown with before based on their staff number or their first/last name. You can also make a person a favorite so they appear high up the list when you click on the name field.

  • Yes, in fact you can choose any one person in your logbook as a default PIC and any one person as a default SIC if you want. For example you can set yourself to be the default PIC or SIC. If you’re flying in a small corporate flight department and you tend to fly with the same colleague a lot you can default them as a a PIC/SIC so their name automatically enters when you start to log a flight. This is done with a toggle switch when you create a person. You can do this at any point as follows:

    1. Navigate to Data > People
    2. Search for the person and select them
    3. Towards the bottom of the screen select ‘Set as Default PIC’ or ‘Set as Default SIC’ by clicking the toggle button.
  • Our in-app search capability for entry fields such as aircraft registrations, offers as much flexibility as possible with finding what you want. Let’s say your Aircraft registration is ‘A1-23BC’ and you’ve logged it before. You can search any combination of that registration such as ‘BC’, ’3BC’ or ‘A1-2’ as an example.

  • Finding someone you’ve flown with before is very fast. Use any of the letters in their name for example, to find Jennifer Mckenzie, you could search ‘Mck’ or ‘Jenn” or even ‘er Mc’. If you’ve stored an ID/Staff Number you can find them with that too.

  • All aircraft registrations, people and airfields can be made a favorite when they’re created by you, or if they already exist, they can be made a favorite by visiting:

    1. Navigate to Data > Airports [or any data type]
    2. Select the item you want to make favorite
    3. Scroll to the bottom and active the ‘Favorite’ toggle.

  • You can carry forward flight hours not yet logged in AvionLog by clicking on Data > Historical Flights.

    Make as many entries as you need. The philosophy feature of this is similar to a paper logbook. Once you’ve finished a paper logbook you carry your old flight hours totals forward to a new logbook. This feature allows you to do that while preserving some of the data quality to make it more searchable and useable in AvionLog’s Reports functions. You can be as detailed or as vague as you choose when carrying forward your previous flight hours.

    Duties behave much the same as flight hours.

  • AvionLog has an extensive database of airports. Due to storage space we do have to use some discretion for which airports are in the app. Also you may be flying from an unlisted airport such as a private strip or an unlisted helicopter landing site. To compensate for this AvionLog has the ability to add a new airport.

  • There are two ways you can add an airport to AvionLog, while adding a new flight, or directly in to the airports database.

    1. Add a new airport while flight logging: in the From or To field entry name your new airport and click on ‘Add new Airport:’. Enter the details you require.
    2. Add a new airport directly in the database by navigating: Data > Airports and click the ‘+’ button at the top right of the screen.

    Latitude and Longitude must be in decimal format. There are websites that can convert hours, minutes and seconds lats and longs to decimal.

    To allow night time calculations from an airport ensure timezone data is entered.

  • A mobile airport is typically a ship or aircraft carrier but can also be used if you want an airport without entering latitude, longitude and other geographic data such as timezones. Just beware that AvionLog won’t know where this airport is and so can’t calculate night flight time and flight distances.

  • Firstly, activate the signature field on your flights page by:

    1. Going to Settings > Display > Flight Editing Fields And Order
    2. Scroll to or search for ‘Sign Flight’
    3. Activate the field by switching on the toggle switch.
    4. Navigate to the flight you want to be signed on the ‘Flights’ navigation tab at the bottom of the screen.

    You can now scroll to where the signature field is, usually at the bottom of the page and click to sign the flight. Ensure you can ‘Edit’ the flight by clicking ‘Edit’ at the top right corner of the screen.

Free Trial


  • Yes you can. AvionLog has built in import features so you can import your data directly in to the app.

  • Yes you can. Our import feature enables you to navigate to the AIMS mobile website and load a logbook report. AvionLog then imports your flights to log them.

  • Step 1.

    In the LogTen Pro app navigate to Reports > Exporters.

    Step 2.

    From LogTen export the following files to your email or a files folder. It’s easiest to email the files to yourself:

    • Address Book Export
    • Export Flights (Tab)
    • Export Places (Tab)
    • Export Aircraft
    • Export Aircraft Types

    Note: Ensure all data is exported. A common error is using a custom date range. Make sure the date range is for all data.

    Step 3.

    1. Navigate to the file on your device. Typically in an email if you chose to share it that way.
    2. Click the ‘Share/Send’ Icon.
    3. Choose the AvionLog app icon or click on the ‘More’ icon and find ‘Copy to AvionLog’.
    4. AvionLog will open but you won’t see the files on the page. Keep going, it is there.

    Step 4.

    RepeatStep 3 for all the files you downloaded in step 2.

    Step 5.

    1. In AvionLog navigate to the LogTen data importer: Settings > Import and Export > Import Data
    2. Select LogTen Pro and click ‘Start Import’
    3. Note: If you were already in this screen and don’t see the uploaded files, navigate out and back in.

    Step 6.

    Drag and drop the green labels next to the correct file you uploaded from LogTen. LogTen Import Match File Names AvionLog will now ask you a few questions about your LogTen data to match to our database particularly for any unknown airports or aircraft. Usually it’s just a slight difference in the way we match data. To match to an aircraft in the AvionLog database choose match and find the aircraft. To create a new aircraft in the database, choose Update Existing.

    5. Click continue.
    6. Once you see your logbook loaded on screen click ‘Next’ in the top right corner of the screen.

    Due to the way some aircraft and airfield codes work you may have to give AvionLog a bit more information. Click each aircraft, choose or search for the correct aircraft and click ‘Match’. If there’s no match, create the aircraft in your local database by clicking ‘Update Existing’.


  • AvionLog is built with your syncing needs in mind. You can move your logbook and individual flights across your devices in any one of the following three ways:

    1. Live Sync - entries made on multiple devices are transferred to each of your online devices in real time. Allows you to use several devices at the same time or to work on a primary device with syncing to additional devices when they are brought online.
    2. Manual Sync - designed as a backup to Live Sync, but it is initiated manually on each device.
    3. Backup Restore - transfer a backup from one device to another. This will take all the data on one device and move it all to another device. It will not respect any entries made on the second device. It’s fast and easy to use if you only make entries on one device, say iPhone, and view on a second device, like an iPad.
  • We use a cloud based solution to keep your data in sync, therefore we need a way to identify you on the server and on all the devices you want to sync between.

    1. Setup sync on your first device. Go to Settings > Sync > select ‘Live’. Then Click Login to setup your sync account. Those credentials can be used on any new devices in the future.
    2. Now go to the same location on any additional devices, click ‘Login’ and use the same login credentials you used in step 1.
  • Live Sync has a lot going on behind the scenes. It comes down to the complexities of deciding which data is right. Sync uses the concept of “last change wins”, meaning if there are two entries competing, the one that was entered last will win and will be synced to your devices. If syncing appears to be not working correctly, use the “Run Full Sync” button on the Settings > Sync page (see instructions below). If that doesn’t work, restoring data from a backup across your devices should put absolutely identical data on all your devices so that sync can get back to work.

    1. Go to Settings > Sync (do this on all devices you sync with)
    2. Look at the ‘Sync Data Version: XX’
    3. The device with the highest number is the one we believe to be correct
    4. On all other devices click on ‘Run Full Sync’
  • If live sync doesn’t work after doing the steps above, use the backup feature to bring your logbook on all devices up to the same state. Note: It may help to disable sync while going through this process.

    While you have internet access choose the device with the correct logbook data and

    1. Go to Settings > Backup > click ‘Backup Now’
    2. On all other AvionLog equipped devices, go to Settings > Backup > Backup Sets and Restore
    3. Choose the backup file you just created and click ‘Restore’ in the top left corner.

    All your devices should now be up to the same correct state. If required re-enable Sync.

  • Yes. You need a WiFi or cellular data connection on each device you want to manually sync with.

  • To start, AvionLog requires that you have enabled at least one backup location, e.g. Box and/or Dropbox. You can then choose one of these as the location where a ‘sync’ file accessible to all devices is placed.

  • Just like the backup capability and other AvionLog features we believe in the aviation industry principle of multiple redundant systems. Manual sync relies on your Dropbox or Box account and you taking some of the actions. Think of it like this, our live sync technology is like GPS, it works great almost all of the time but it’s not perfect (just yet). Manual sync is like a VOR backup, it’ll get you there but with just a bit more work.

    1. Make sure all devices to be synced are logged in to the same Box/Dropbox account(s)
    2. On all devices go to Settings > Sync > Select ‘Manual’
    3. On all devices click ‘Set Manual Sync Location’
    4. Click on Dropbox or Box (make the same selection on all devices, if you cannot see the same option then you need to login to that service on that device)
    1. On one device click ‘Run Manual Sync’ and wait until it’s complete (a few seconds)
    2. Repeat above step on all devices
    3. Continue to repeat on all devices one by one until all data is in sync
