Brief description of the issue:

Reducing the physical throttle so that the in-cockpit throttles go into the FI detent and IDLE-IDLE is shown on the PFD causes the plane to start decelerating rapidly as if it were in flight idle, but the engine instruments show that it isn’t (torque will be 25-30%; actual flight idle torque is in the low to mid single digits), and no large torque changes occur.

Conversely, increasing the physical throttle so that the in-cockpit throttles move just barely out of FI stops the unexplained deceleration, again with no large torque changes.

Both of the screenshots below were taken at 230 knots by first accelerating to 250 knots and then setting the throttles to the desired position and allowing the plane to decelerate through 230 knots. The first one was taken with the in-cockpit throttles just barely above FI, and the second one was taken with the in-cockpit throttles in FI.

Notice how the torque difference between the two screenshots is only about 1.5%, but in the second screenshot, the airspeed trend indicator shows the plane decelerating at least twice as quickly.

This kind of sudden deceleration should be accompanied by a major reduction in torque as the props go to fine pitch. It’s impossible otherwise.

This issue may or may not be related to the throttle position mismatch bug here:

ATR - The in game throttle position does not match the real hardware throttle in flight when in the FL Stage

Provide Screenshot(s)/video(s) of the issue encountered:

Detailed steps to reproduce the issue encountered:

1. Accelerate to a high speed
2. Reduce in-cockpit throttles to just above the FI detent (not in the detent!)
3. Observe engine torque and airspeed trend indicator
4. Accelerate to a high speed again
5. Reduce in-cockpit throttles into the FI detent
6. Observe engine torque and airspeed trend indicator again
7. Torque between the two configurations will only differ by 1-2%, but the FI detent magically gives at least twice the deceleration.

PC specs and/or peripheral set up if relevant:

• VKB Gladiator NXT joystick
• Winwing Orion 2 F/A-18 throttle
• VKB T-Rudder pedals
• Controls configured through SPAD.neXt

Build Version # when you first started experiencing this issue:
