The cockpit windows have this strange grey reflection that looks completely unrealistic, and it really breaks the immersion. It doesn’t even look like a proper NEO. Hopefully this bug will be fixed.
Regarding the PTU sounds, it was mentioned that they were updated and should be more realistic, but when playing, it’s exactly the same sound as on the other A320 versions. Apart from the engine sound, which also isn’t very accurate, there’s this continuous “whistling-like” noise when the engines are at idle which is not realistic at all.
Regarding the whale sound, yes, the actual sound sample is realistic, but there’s an issue with it. It starts sounding every single time when the engines reach those parameters (e.g. 300–400), no matter if the thrust is increasing or decreasing the power, if the thrust is in those parameters during descent you can hear it the whole time. In reality, this sound is only occur when the thrust is increasing. I hope this makes sense. These small details are what really make the difference.
As for the lights, the issue is already known and hopefully will be fixed soon, and I would also be happy to see that finally in the a320 the beacon light is flashing the top part of the wing and winglet as well like in real life. What’s also missing are the fuel pumps which I like to call the “signature sound of an a320” and the electric pump is not realistic at all, it doesn’t match real-life sound in any way.
I really hope the A20N gets proper improvements, with accurate sounds, lights, and detailed systems. It would be a shame to add a new aircraft just for the sake of “adding it”, because right now that’s exactly how it feels, like something rushed just to be included. Don’t take it as a complain, it’s just a friendly feedback.
Thanks for reading. 🙂
