    There is no one answer for this question. If the plane was empty and departing at sea level with the wind at 0 knots, then the power setting would be quite different than fully loaded at 8000 ft above sea level. The amount of thrust needed to lift off the aircraft depends on the wind, weight, and elevation. Power settings are also different for each aircraft.

    Landing power is adjusted to keep the aircraft within the proper airspeed for the altitude and flap setting. The landing power needed for a crosswind landing with maximum payload would be different than cruising in on a calm day at 50% capacity.

    I will leave it at this or else you would be up all night reading each individual scenario and the power setting calculation.
