Crew App - Offline Mode

Calendar & Duties on Android

When your device is offline (e.g., in airplane mode with all radios disabled), the FL3XX Crew App does not fetch new roster or flight‑count data from our servers. Instead, it displays only what’s been saved in your device’s local cache. If you open the app offline without having previously cached any data, the calendar will appear blank.

By default—after you log in while connected to the internet—the app automatically caches your roster duties and flight counts for the current month, plus 15 days before and 15 days after that month. In offline mode you will see duties only within that cached window; any dates outside it will be empty until they’re added to cache.

To ensure you can view past or upcoming duties offline, simply scroll the calendar (or navigate to the desired month) while online so the app downloads and stores that month’s data. For detailed flight information (beyond the flight‑count summary), use the app’s Download Flight feature while connected; downloaded flights remain accessible offline even if they fall outside the default cached range.

When using iOS devices in offline mode, the app will only display flight information for days that you have previously accessed.

Flights

The app includes an offline mode that enables you to access your flights and view all the details from the most recent update, even without an internet connection. Your flight data, including any changes you make, will be saved and stored locally for easy reference. This means that you can continue to view and edit your flight data, including any attachments, whether you're offline or if you reopen the flight in the app.

To view flights offline, you'll need to open or download the flight while you're online so that you can access it when you're offline. Simply click on the flight and open any of the icons on the flight details page. Alternatively, you can swipe left on a flight and select the download option, or use the Download option in the top right menu.

Once you've done that, you can open the flight offline and make any necessary changes, with or without an internet connection. When you regain online connectivity, you can press the orange cloud within the flight or simply tap on the flight again if you've exited it. The mobile app will compare your local records with the new records from the web app. If there are any conflicts between the two sets of records, you'll be notified. This ensures that any changes you made while offline are synced with the web app, allowing you to seamlessly continue working with the most up-to-date information.

Poor Network Conditions

It's crucial to understand how the Crew App handles network connectivity challenges, particularly during tasks that require data transmission, such as uploading a Post Flight document. Should you find yourself in areas with suboptimal network conditions, the app attempts to proceed with downloading or uploading processes. However, it does not automatically switch to offline mode in such scenarios. These attempts might result in a timeout after 30 seconds, leading to unsuccessful data transmission.

To mitigate this, users experiencing poor network connectivity are advised to manually activate Airplane Mode on their device. This action forces the app into offline mode, allowing it to store data locally without attempting any online transactions. Once a reliable network connection is re-established, users can then synchronize their data with the app. This proactive approach ensures that your work progress is preserved and subsequently synced accurately, optimizing app functionality and data integrity in varying network conditions.
