ATA 31 – Fusion Equipped King Air Software and Databases

The Fusion avionics system requires a number of software and database files to function. This information is to clarify the software and database requirements for current production, factory-installed Fusion Avionics in all King Air models. The data in all three Adaptive Flight Displays (AFD) must also match or the system will flag an error upon initialization and present a configuration fault on all screens. The following tables define the items loaded into current production airplanes. Files can be accessed and the target component can be uploaded. If an AFD file becomes corrupted, that individual file or database can be reloaded. If an AFD, Aircraft Personality Module (APM), Audio Storage and Playback Unit (ASPU), or Electronic Standby Instrument System (ESIS) configuration module is replaced, all of the respective files and databases will need to be reloaded into that unit. A replacement ESIS Remote Sensing Unit (RSU) should come from the vendor preloaded with the correct flight software, but can be reloaded if required. Note that the maintenance test box TE79-KA-MAINT or software loading plug presented in King Air Communiqué 2016-01 is required to load software into some components.

To access the Textron Aviation-supplied data, log in to the customer support web page at www.txtavsupport.com. If you have not previously registered, click on the Register link and complete the registration process. Once logged in, select the airplane model on the left side of the page. On the next page in the AVIONICS box, select the Rockwell Collins Pro Line Fusion Support link. Select your airplane model from the drop down menu, enter your airplane serial number and click submit. The available software will be listed. Save the zip file locally and unzip them. Copy the files to the USB drive you will utilize on the airplane. It is recommended that any new USB drive be formatted to FAT 32 before being utilized to eliminate any non-system files. Save that program and the database files to a separate USB device. Note that the ICIT and program folders need to be in the root directory on the USB drive for the displays to locate them. For best results keep the database and program files on separate USB devices. For vendor data, contact the source listed for the current method of access (reference this Communiqué on the Textron Support website at www.txtavsupport.com).

ATA 32 – Tire Usability Rev 2

King Air Communiqués 99-005 and 2003-01 touched on the subject of tires used on various King Air models. Since the last revision, there have been some models added. The chart below is updated with the new King Air models.

Any tire brand that meets these specifications can be used on King Air airplanes. The links below provide a guide to the most popular brands. There may be others.

ATA 56 – Windshield Electrical Connections

Owner/operators that replace an original King Air windshield with an overhauled windshield may find a difference in the electrical connector block. This is common in overhauled windshields that have an extra sense element connection. The following photo shows how these windshields should be wired.

ATA 56 – Windshield Electrical Connections Miswired

The wire terminals to the windshield connector block are the same size. It is possible to connect the wires at an incorrect location. A miswired windshield could be operated continually in high power mode with no significant effects, but it would fail shortly after low power mode is selected. Reference the applicable Wiring Diagram Manual and the wire codes on the wires to make sure that the windshield wires are connected correctly.

The following photos show the end result if the windshield is miswired.
