Sudden power loss

Featured Replies

Hi guys,

I have a few times experienced a sudden and unexplainable power loss with the 744.
There are no system to it as it have happened while taxiing out, initial climb and today 3 times on final approach. It has mostly happened with the RR Freighter, but today it was the PW pax version for the first time.

What happens electric power and engines fail leaving me with a almost cold and dark cockpit for a few seconds until it comes back alive as just before it goes out.

There are plenty fuel and I use AS16 for weather which fairly quiet.

Best regards

Do you have any hardware axes assigned as mixture controls for use when flying piston models? I know that in the NGX those levers can affect the jet engines - they act like fuel shutoff controls when the NGX is active. Perhaps they would affect the 744 the same way. 

I always advance the two hardware mixture controls to full forward when flying a jet model. With the NGX, if I forget and leave them fully back in the idle cut off position, the engines will start OK on the ramp, but will flame out the moment I advance the power levers to taxi.

If you don't have hardware mixture controls assigned, perhaps a hardware or keyboard control assignment you are using for something like flaps or landing gear is also bound to engine mixture controls as well.

What hardware controllers do you have, and do you assign controller functions directly in the FSX or P3D menus, or using  FSUIPC?

Thanks Jim,

I am using CH Products yoke and hadn´t thought the axis could be the reason.

Since I don´t fly GA I have deleted the 2 other axis so hopefully I won´t encounter those problems again.

Best regards

Following from what Jim said.  I had something similar.  Engines 1+2 and 3+4 shutting down simultaneously.  I went to fsx assignments and deleted the controller assignments except for the x and y axes.  That fixed the problem.
