3、航高度的时间少于“最大爬升推力+最大起飞重量”爬升至巡航高度的时间为原则制定了如下程序：起飞全重（TOW）200吨，选择D2；200吨起飞全重（TOW）210吨，选择D1；起飞全重（TOW）210吨，选择MCL。在通过起飞全重确定了减推力爬升的级别后，机组必须确定该减推力爬升满足运行限制的要求（如ATC的要求、SID高度或爬升梯度的要求等）。在可行的情况下选择DCLB2，当DCLB2时的推力级别 运行限制时，飞行机组应执行DCLB1级别爬升，如果需要，使用最大爬升推力(MCL)。注：机组可通过 FCOM 中性能-爬升-减推力爬升图表来检查使用减推力后，该级别的减推力是否满足高度限制。To al

4、l A330 pilots,In order to increase engine life, improve engine reliability and reduce directmaenance costs, according to the relateds of company, now flight crew arerequired to select suitable derated climb level as required before takeoff.There are two derated climb levels: Derated Climb 1 (DCLB1)

5、and DeratedClimb 2 (DCLB2). DCLB1 redutheum climb thrust by 5% to 10%;DCLB2 redutheum climb thrust by10% to 15%. Rolls-Royce Limitedformulates the following procedure according to the principlet the time ofusing reduced thrust to climb to cruising altitude is lessn the time of using“um climb trust +

6、um takeoff weight” to climb to cruising altitude:Takeoff Weight (TOW) 200 ton, select D2; 200 ton Takeoff Weight(TOW) 210 ton, select D1; Takeoff Weight (TOW) 210ton, select MCL.After confirming the reduced thrust climb level by TOW, flight crew mustconfirmt the reduced thrust climb meets the requir

7、ements of operation limits(such as the requirements of ATC, SID altitude or climb gradient, etc.). SelectDCLB2 under feasible condition. When thrust level of DCLB2 can not meet therequirements of operation limits, flight crew should implement DCLB1 level climb.If needed, useum climb trust (MCL).Note: Flight crew can check whether this reduced trust level meets therequirements of altitude limits after using reduced trust by
