Propeller RPM (Np) issue


Recommended Posts


I am using version 1.13 for the moment. Yesterday, I did a short flight with a brand new airframe and all components in an excellent shape (looking at the maintenance manager).

Today, I left it on ground power for a while to familiarize myself with some systems and procedures. So, after a while I decided to try and start up to do a short flight. I had a normal start, and then I disconnected the GPU and put the generator to MAIN. But, when I put the power lever into flight idle, the propeller should unfeather and stabilize well above the yellow band. But in this case, the propeller would not accelerate beyond the yellow RPM, even with the power lever placed in flight idle. I tried a couple of times to feather (HI IDLE and LO IDLE) it, and then unfeather it again. So, I shut down and check the maintenance manager. Every component ok. Never seen this behaviour before. Any clues?
