Even if it is an impossible turn caused by the MSFS flight planning. I do find that the autopilot is smart enough to not actually “turn 150°” but instead turn using a wider radius within safety margins and rejoin the path at another position.
Sometimes the Autopilot also doesn’t wait until it passes the waypoint, and on turns like that, it just make the turn earlier so that the wider turn radius that it does can intercept the next part of the flight path.
I guess for most people who are used to the proper flight planning it’s easy to spot issues like this from the MSFS flight planner. But for people like me, who sees “the result speaks for itself” I tend to not really care about how the flight planning does it. as long as I can safely get from point A to Point B without stressing the aircraft, I’m happy.
