How do I connect an Avidyne IFD440/540/550 to Stratus WiFi

If you have a Stratus 1S, 2, or 2S, you can configure your IFD440/540/550 navigator to connect to the Stratus WiFi network. This will allow ForeFlight Mobile on your iPad or iPhone to exchange flight plans with the IFD and for ForeFlight Mobile to receive ADS-B weather and traffic directly from the Stratus.

Guidance on connecting your IFD to a Stratus is found in the IFD Pilot's Guide:

The WiFi system can be configured to work in "Local" mode where the IFD acts as a "server" or access point, or, "Remote" mode where the IFD acts as a "client" and can attach to a separate remote access point which allows the IFD to join other existing WiFi networks (e.g. connect to an existing Stratus- ForeFlight network).

The factory default WiFi network ID (SSID) and password are “LIO_WIFI” and “abcdef1234”. Both are changeable values via maintenance mode and separate SSID and passwords can be created for both the "Local" and "Remote" modes – instructions for doing so can be found in the Installation Manual.

NOTE: ADS-B weather and traffic received from the Stratus cannot be displayed on the IFD.
