So recently I tried to Figure out why the engines in the Learjet 45 were not shutting down all the way. I pulled the throttles to cutoff but the engines kept running at around 1.9 percent, so they were almost shut down, but not completely. I was wondering if anyone else has experienced this issue, or is it just my Device (iPhone 7 plus)?
The engines can windmill for some time and because of residual heat they can also keep spinning. I'll increase the internal friction caused by the accessories and bearings.
