“The Q400 is not yet supported on the Prepar3D V3.0 platform. Although it is possible to fly the aircraft, the known issues are:
1. No cabin sound
2. Stuttering of the aircraft from the outside view when in the air
There are are few other tweaks and adjustments that will be required before testing for the new installer is completed.
When the appropriate fix becomes ready we will publish the announcement. Questions of it release date/time frame will be ignored.
