Description

Certain Experimental SkyView HDX displays - manufactured during or after March 2022 - can exhibit adverse behaviors when equipped with Wi-Fi Adapters (Dynon p/n 102405-000). These behaviors include display restarts or display freezing, which can result in the partial or complete loss of flight instrumentation without warning.

Immediate Action

Remove USB Wi-Fi Adapters from affected displays before further flight.

Since this behavior only occurs with Wi-Fi Adapters connected, removing them will prevent the described adverse behaviors from occurring.

Update software per below as soon as practical.

Solution

SkyView System Software Version 16.3.2 and later contains a fix for this problem.

Download and install SkyView System Software version 16.3.2 or later to each affected display.

Once a display is running SkyView 16.3.2 or later, Wi-Fi Adapters can be connected and used.

Time in Effect

This technical service bulletin is in effect indefinitely.
