ATA 31 – Fusion Equipped King Air USB Device Requirements
Fusion equipped King Airs require periodic database and software updates. On airplanes without the IMS 3500 system, this is performed through the USB port on the AFD 3700 displays. The port on the AFD 3700 is compliant to USB 2.0 standards. The Rockwell Collins airplane maintenance manual excerpt shown below, currently calls for a USB 2.0 or equivalent device formatted with FAT 32. Collins has provided additional clarification that a version 3.0 USB device is an acceptable equivalent as long as it is USB 2.0 compatible and has a capacity between 4Gb and 32Gb. Collins will be adding clarification to the reference below in a future update to the manual.
