Pratt & Whitney PW1100G Engine Transient Whine Sound Missing After Latest Update

[Mohamed Elkafas]

Hello,

After installing the latest update for the FSLabs A321neo with the Pratt & Whitney PW engines, I noticed that a specific engine sound characteristic appears to be missing.

In the real aircraft, when the PW1100G engines are at idle and the thrust levers are advanced slightly, there is a distinctive high-pitched whine/howling sound during the initial power increase. This characteristic sound is especially noticeable during the first few seconds of spool-up or when the engine transitions from idle to a higher power setting. After this short transient phase, the engine sound returns to the normal PW1100G operating sound.

Before the latest update, this specific Pratt & Whitney transient sound characteristic was present, but after the update it no longer appears to be audible. The engine sounds generally normal, but this unique PW1100G "whine" during initial thrust increase seems to be missing.

Could you please check if this was changed intentionally or if it is a sound regression introduced with the latest update?

Thank you.
