June 2, 20215 yr Hello! I recently switched to P3DV4 and purchased the 757 that I used to enjoy in FSX, but I'm having overspeed in the climb. With the climb AT mode selected (and even with it de-rated on a heavily-loaded 757) this airplane will NOT meet any sort of speed restrictions. It blows right through 250 below 10,000 (with the limit set in CDU) and when it levels off in between climb altitude changes, it accelerates well into overspeed territory. The throttles also don't appear to be reducing power correctly; they will start to reduce and then jump forward again. I don't understand why this is happening and I really want to be able to enjoy the 757 again. I've seen others report this issue and I'm curious if anyone determined a resolution. Thank you for the help!
June 2, 20215 yr You might try checking to see if your throttles are noisy/spiking--I don't have this add-on, but I have seen with others that a change in the axis value often overrides the A/T. Generally when on A/T I park my throttle levers at max, where I have a sufficiently wide end-of-travel dead zone defined such that any wobble in the raw throttle axis value stays within the dead zone and does not produce a change in the value sent to the sim.

Thank you for the help! Well I mentioned this an issue which relates to the 787 last July and yet to be addressed. whereby if I assign the A/T toga to a keu in my saitek throttle quadrant the aircraft overspeeds over 10000ft. mike
June 5, 20215 yr Author @w6kd Good idea, I'll give that a try; I also have the throttle reduced to zero on the physical throttle hardware. Thanks for the input!
