  • NavData: airports, waypoints, procedures (AIRAC cycle every 28 days)

  • Obstacle Database

  • Terrain Data

  • Charts (if supported)

Jeppesen provides most of these via their Jeppesen Data Service for Avidyne products 

✅ What You’ll Need Before Updating

  1. Jeppesen subscription linked to your Avidyne system ID

  2. Jeppesen Distribution Manager (JDM) installed on your computer

  3. A USB flash drive (FAT32, between 4–16 GB, WINTEC recommended) Avidyne Pilot Support

  4. Physical access to your IFD410 unit (ensure the aircraft is grounded)

🔧 Step-by-Step Update Process

1. Set Up Jeppesen Distribution Manager (JDM)

  • Download JDM from Jeppesen’s website

  • Log in with your credentials and confirm your IFD410 system ID

  • Make sure subscriptions for NavData, terrain, and obstacle datasets are active 

2. Prepare the USB Flash Drive

  • Format the USB drive to FAT32

  • Use a reliable 8–16 GB WINTEC flash drive or equivalent 

  • Insert into your computer; JDM should detect it automatically

3. Download and Transfer Data

  • In JDM, select the IFD410 as the target device

  • Choose which updates to download (NavData, terrain, obstacles, charts)

  • Begin the download and wait for completion before removing the USB

4. Enter Maintenance Mode on IFD410

  • On the aircraft, enter Maintenance Mode before updates begin—this is required under FAA rules (14 CFR Part 43, App A) 

  • Navigate to the Update tab, which lists all files on the USB drive

5. Load the Database Files

  • Select desired files using the knob or touchscreen

  • Press Proceed to start the update

  • Stay powered via ground power and do not interrupt the process until completion—power loss can corrupt data 

  • Upload times vary—NavData: ~20 s; Charts (if applicable): up to several minutes depending on size

After installation:

  • Go to Aux > System > Status > Databases to verify all cycle dates

  • Ensure your NavData reflects the current AIRAC cycle

  • Use map overlays and chart modes (if supported) to visually confirm functionality

⚙️ Troubleshooting Tips

IssueFix
USB not detected Try reformatting it to FAT32, use a WINTEC drive
Wrong files uploaded Clean old files off USB before reusing
Update errors during maintenance Use reliable ground power; do not reboot mid-update
Incorrect region or data cycle Confirm your Jeppesen subscription covers the correct region

  • Keep a backup drive with the previous cycle if legally allowed

  • Maintain accurate log records of database update cycles for compliance

  • Ensure unit firmware (software version) is up to date via an Avidyne dealer if needed—especially for newly released features or bug fixes
