95% torque for take off, and then maintain 90% through the climb (you can push 100% up to FL260). For cruise use the torque you like without exceeding 250 kts or M.67. Start your descend earlier than what the FMC suggests, or set on the DESCEND page a descend angle of 2*. You must keep some torque (do not descend on idle) to keep oil warm.
In Cruise flight with the AP set I will get a pitch oscillation and see that the pitch trim is set to significant pitch down. I turn off the AP and the TBM900 pitches up significantly. I have been able to manually set pitch trim for level flight and turn on the AP. The pitch oscillation goes away. It appears the AP is flighting the pitch trim setting. I would have expected the AP uses pitch trim to control altitude and climb or descent. Any similar experiences. WRS
