MilViz Releases Service Pack 1 for King Air B350i

Popular aircraft developer Military Visualizations has released the first service pack for their King Air B350i addon for Prepar3D. An extensive changelog was released over on the MilViz forum, detailing what we can expect to see in the latest version of this turboprop.

While no major changes were announced, a wide array of smaller fixes have been made that mostly concentrate on the FMS, systems, PL21 avionics system and visual tweaks.

Originally releasing in December 2019, the King Air B350i addon is a faithful rendition of the famous Beechcraft Super King family member and boasts a full FMS-3000, TrueGlass integration and realistic sounds. 

The latest rendition of the King Air B350i is available from both the MilViz store and SimMarket for $79.99 and €70.08/£63.01 excl. VAT respectively.

Existing customers can grab SP1 free of charge from the MilViz support forum or the original download link they received upon purchase.  As of this date, the only simulator that supports this product is Prepar3D Version 4.5.
