Hello All,
I was flying at 27000-29000 ft at M1.4 today (on my way home after a zoom climb, if you wonder why I’m so fast at this altitude) and I put my throttle at idle position. Then I hear a “Bang” noise, then another one after about 30 seconds, then repeat every 30 seconds-ish. There’s no cockpit shaking nor stick shaking (I’m using a FFB stick), just this “Bang” noise. It goes away if I push the throttle back to mil position.
I’m not sure if this is a compressor stall? If so, how is that possible? Because in my understanding the engine won’t go below certain power setting (possibly mil power?) when supersonic, regardless of the throttle position. In fact I don’t observe any change in my engine RPM/TIT/FF indicator when I move the throttle between idle and mil.
Would love to know the reason behind this! Thanks in advance.
