整流罩TAI配置代码基于P5-11发动机和机翼防冰面板开关。电子发动机控制器（EEC）从显示电子单元（DEU）标签352位25（Eng 1）或位26（Eng 2）读取信息。通过P5-11发动机和机翼防冰面板的防冰控制开关将DEU设置为True。EEC将单个位转换为两位代码（标签276，位18和位19）。对于每台发动机的EEC（如D226A101-2所示），如果标签276 B19=0和B18=1，则发动机向奶牛提供零整流罩热防冰（TAI）排气。如果标签276 B19=1且B18=0，则发动机向其整流罩供应整流罩TAI排气。
当发动机防冰处于关闭位置且前罩防冰阀位置开关指示关闭时，TAI指示消失。当发动机防冰处于关闭位置且前罩防冰阀位置开关指示打开时，琥珀色TAI指示出现。
