hello
Actually, A/T will do that automatically. Pilot monitoring is supposed to monitor if the A/T does it as it computed in N1 page or Take off page of the FMS. That is, PM will compare the value of what A/T brings the trust lever, with the value computed and displayed in FMS. Most likely it will be the same resulting with the call out "Take off trust set". In some cases somehow A/T doesn't move forward the levers as it is supposed to do. In this case The PM is expected to adjust power manually.
