So… when I start the engine, it shows N1=18%, which is impossible. Turbine engines run 60% RPM at idle producing about 15% of max thrust. or less, recips would be around 30-40% of max RPM at idle. Could they fix it?
You need to specify what aircraft you’re refering to. :)
All turbofan/turbojet powered aircraft
you are talking about n2 which is the rpm of the engine core/compressor n1 is the rpm of the big fan on the front… they are very different
the n2 doesnt appear to be displayed in if
Oops I forgot it could be 2 spools
