Microsoft Flight Simulator Patch Update

Microsoft Flight Simulator has released its update, which latest update implements the new AIRAC cycle 2105 and FAA data for its navdata solution. Moreover, it fixes a crash and here is the official list of changes and additions made with this patch. 

This patch doesn’t have much going on in the major game changes department, but it does one certain thing right when it comes to reducing download size. In fact, the download has been reduced from 170+ GB to 83 GB, which should mean a massive improvement in your hard drive space. However, if you’re curious about the rest of the changes,

Here is the full list of patch notes for Microsoft Flight Simulator Update
