A mathematical model has been used to describe experimental results for core and skin temperatures in subjects undergoing a rest/activity cycle in two aircrew clothing assemblies at two environmental temperatures (wet bulb, globe temperature (WBGT) indices of 25.9 and 28.9 degrees C). The model presented compares well with published data for subjects in standard aircrew equipment assemblies. Aircrew flying at a WBGT of 28.9 degrees C in chemical defence clothing may reach an unacceptable level of mean body temperature within 40 min and deep body temperature will rise at 1 degree C.hr-1. To prevent deterioration in flying performance during repeated sorties, an alteration in the work/rest activity pattern or the introduction of effective cabin or personal conditioning systems may be required,
一个数学模型已被用于描述在两种环境温度（湿球、黑球温度（WBGT）指数分别为25.9摄氏度和28.9摄氏度）下，穿着两种空勤人员服装组件经历休息/活动周期的受试者的核心温度和皮肤温度的实验结果。所提出的模型与标准空勤人员装备组件中受试者的已发表数据比较吻合。穿着化学防护服在WBGT为28.9摄氏度的环境中飞行的空勤人员可能在40分钟内达到不可接受的平均体温水平，深部体温将以每小时1摄氏度的速度上升。为防止在多次飞行任务期间飞行性能下降，可能需要改变工作/休息活动模式或引入有效的机舱或个人调节系统。
