According to Su Tzu-chuan, the engines have withstood tests as rigorous as operation at a simulated altitude of 60,000 meters, wind tunnel speeds of Mach 2.5, 12 hours of operation at minus 40 degrees centigrade and operation in blown sand as fierce as a Saharan sandstorm with results fully up to design requirements.
舒孜川說明，IDF 發動機已通過了模擬六萬呎高空、二．五倍音速的風洞實驗；處在零下四十度低溫中十二小時後，也能照常發動；經過宛如在撒哈拉沙漠中風暴吹襲的吹沙實驗，結果也符合設計需求。
