目前我国森林火灾的扑救手段很落后,特别是在飞机喷洒灭火方面,仅有为数不多的国产运五型飞机。这种飞机不仅量小,携带化学灭火药剂有限(最多一吨),对稍大一些的森林火灾无能为力,而且由于只能飞回机场添加灭火剂,对于距离较远的火场,往返时间长,架次衔接不上,灭火效果和经济效益都较差。为了改变这种落后状况,民航黑龙江省分局和林业部东北航空护林局协作研制成功米八型直升飞
At present, China’s forest fires are very laggard in fighting for firefighting, especially in the area of jetting firefighting. Only a handful of domestic-shipped five-type airplanes are available.
