Normal rated thrust

Web1 de set. de 2012 · Turbofan engines are most efficient at nominal RPMs of 90-95% and relative thrust of about 80% of maximum rated thrust although this is not true for every altitude and every engine (Daidzic, 2012). WebThe rated thrust is lowered in Derated takeoff but not in Assumed Temperature takeoff. Therefore, by calculating the minimum speeds based on a lower engine rating, the pilots can be ensured that sufficient directional control can be maintained on a slippery runway, whereas there is no such guarantee for Assumed Temperature takeoff.
