As I remember, since the 2017 update, the engine sound now is the opposite of before the update. I don’t know if there’s anyone notice this.
So when climbing and throttle up to desired speed (usually after 10.000 feet we change the speed to 300 knots from 240), the engine sound from front side and rear side is now switched. What used to be the sound of the engine thrust (rear engine sound) is now becoming front side sound, and vice versa.
Is this on purpose by FDS?
Or maybe you guys confused with what I have explained above? :)
Maybe you would like to try doing a flight and listen to the engine sound from front side and rear side when throttling.
This is not a complain post, just curious. :)
