Derated Takeoff` Short runway: TOGA is used & V1 min is high V2 V1=VMCG VR 35ft ACC STOP This is due to excess of thrust The present take off weight is VMCG limited, because of a short ASD and a high V1 min. We can observe a large excess of thrust after lift off. This excess of performance (thrust) is penalizing on ground and not necessary after lift off. V1=VMCG VR 35ft ACC STOP If, for the same TO weight, the maximum TO thrust is reduced or derated by a given percentage of X%, the associated VMCG is decreased. Consequently: – – – V1 may be reduced, ACC/STOP distance is decreased accordingly, climb out performance may still be met. Thus derated take off may allow to increase TO weight DATE: SEP 2006 Page 137 ZUAD172 FLIGHT CREW PERFORMANCE COURSE A318/A319/A320/A321 PERFORMANCE TRAINING MANUAL TAKEOFF PERFORMANCE REMINDER The Derated TO thrust is therefore to be considered as the maximum TO thrust rating available for a given take off. It determines the new VMCG and the new VMCA applicable during that take off.
