The Federal Aviation Administration (FAA) is proposing a new airworthiness directive for specific Gulfstream Aerospace Corporation GVII-G600 airplanes. This proposal is in response to a reported issue where the pitch attitude on the primary flight display can freeze for up to 20 seconds due to a software failure. To address this, the FAA suggests updating both the data concentration network and the flight deck master operating system software. The aim of these updates is to prevent misleading flight information that could lead to a loss of control in certain flight conditions.
Simple Explanation
The FAA wants some Gulfstream airplanes to get a software update because there's a problem that can make a screen showing important flight information stop working for a little while, which could be unsafe. They are suggesting fixing the software so pilots always see the right information.
