AT_Youmu Posted July 19, 2020 Share Posted July 19, 2020 I used to set it to HI during take-off , landing and AAR. Thought I can get faster engine response. But I just notice that in idle position, no matter its in LOW or HI, the fuel flow doesn't change a bit. Is it right? If its right, the switch only changes the way RPM display?

Captain Orso Posted July 19, 2020 Share Posted July 19, 2020 Low is the default setting, and what you should be using. The switch choses which compressor step is displayed, and I'm not even sure if it is working. Either way, it only a display choice. It doesn't affect performance in any way.

Thebaron45 Posted July 19, 2020 Share Posted July 19, 2020 There's 2 "compressors" in the Pegasus engine: A Low Pressure High Bypass fan that you see in the intake, and a High Pressure compressor that is further inside the engine. They have separate axles and rotate at different RPM's. The switch just changes which compressor you want to see the RPM of. It's only real use that I know of is troubleshooting. Low is normally used. Link to comment Share on other sites More sharing options...
