The invention belongs to the field of aircraft thrust management, and particularly relates to an implementation method of a thrust-reduced takeoff function of an aircraft. The method comprises the following steps: step 1, determining a thrust-reducing takeoff scheme, and dividing the thrust-reducing takeoff scheme into two thrust-reducing levels, namely a first thrust-reducing level and a second thrust-reducing level; wherein the first thrust reduction level adopts a level thrust reduction mode, and the first thrust reduction level comprises a plurality of thrust reduction levels; setting a second thrust reduction level between the first thrust reduction level and the second thrust reduction level, wherein the second thrust reduction level adopts a flexible temperature thrust reduction mode; step 2, converting the thrust value of each thrust reduction grade under the standard condition into a takeoff weight grade according to an equal thrust-weight ratio mode; and 3, selecting a thrust reduction level according to the takeoff weight to calculate the takeoff performance, judging whether the selected thrust reduction level meets the takeoff requirement or not, if so, taking off by using the current thrust reduction level, and otherwise, entering judgment of the next thrust reduction level.

    本申请属于飞机推力管理领域,特别涉及一种飞机减推力起飞功能实施方法。方法包括:步骤一、确定减推力起飞方案,将减推力起飞方案划分为两种减推力层级,分别为第一减推力层级以及第二减推力层级;其中,第一减推力层级采用等级减推力方式,第一减推力层级包括多个减推力等级;在第一减推力等级与第二减推力等级之间设置第二减推力层级,第二减推力层级采用灵活温度减推力方式;步骤二、将每个减推力等级的标准条件下的推力值按照等推重比的方式换算为起飞重量分级;步骤三、根据起飞重量选取减推力等级计算起飞性能,判断选取的减推力等级是否满足起飞要求,若满足,则使用当前减推力等级进行起飞,否则进入下一减推力等级的判断。
