Brief description of the issue:
When on descent and you pull back the throttle, for a long time nothing will happens but there will be a one millimeter zone where the speed drops 15-30 knots. And if you move the throttle slightly forward again it will pick speed up again.

I believe this is the same issue I have described here: ATR decelerates as if it were in flight idle when it isn't
In the video below, pay attention to the engine torque and airspeed trend indicator as I go in and out of the flight idle detent. In a real turboprop, torque and propeller drag both depend on blade pitch, and are inversely related. This means you can’t have a large change in drag without a large change in torque.
And yet, that’s what’s happening here. Going into the flight idle detent magically causes the propellers to generate a massive amount of extra drag even though the torque changes by less than 1%. This is physically impossible for reasons described above.
It seems that the plane only looks at the cockpit thrust levers and applies a lot of extra drag to simulate prop drag whenever the levers are in the flight idle detent. However, the cockpit throttle levers don’t match what the engines or the user’s physical throttle levers are doing, as described here: ATR - The in game throttle position does not match the real hardware throttle in flight when in the FL Stage which causes this weird behavior of the plane decelerating like it’s in flight idle even though the engines are still producing ~30% torque.

I suspect there may be an invisible spoiler.
Can’t tell for sure because the .cfg’s encrypted, but this is an old trick of flight dynamics developers to make turboprops decelerate faster, goes back to the FSX days.
To be executed properly, the invisible spoiler needs to be coded to deploy progressively, but this behavior as described is exactly the same as we saw with the Twin Otter where the spoiler would deploy fully and instantly at a predetermined throttle position.

This is still happening after the update even though the changelog says it was fixed.
This has been reported as unable to repro on ATR Update 1.0.8 - if you are still experiencing this, please let us know and if possible, provide your reproduction steps and peripherals again. Thanks!
Will retest tonight and report back
This appears to be fixed now. The numbers make much more sens now and there’s no thin line between going full power and massively slowing down.
