This is a feature that we are exploring for future application, but the audio team needs actual usage data on it in order to determine its viability.  Please feel free to let us know what you think.

➡️  Fixed Icing issue in Airbus A320 Neo – Instruments will no longer fail, reducing airspeed to zero when encountering icing
