PMDG 747 v3 Eng 3 and 4 failure every flight

[swisscathal 1]

Hi,

 

Not sure if Im doing something wrong but every flight now I get an engine 3 and then engine 4 failure while on  the descent. Has happened in three different flights, three different aircraft but always on descent.

 

Ive now switched off random failures but this must be a bug or am I flying her wrong??

 

thanks

FSUIPC for throttle and/or mixture mappings?

I hope your engineers topped the engine oil up.

 

Do you have remember oil quantity option set ON?

 

What in particular is causing your engine failure?

Hi, yes fsuipc for all control mappings.

Yes I do

Failure is caused by an oil leak. Oil pressure then drops and temp rises then engine failure.

 

I ran a service on the qantas 747 after first failure, but then during a flight with newly downloaded Martin air it happened again, and then next flight with cargo Lux same failures always on descent engine 3 then 4

 

Thanks

If remember eng oil quantity is on then it should fail at beginning of next flight and not 12 hours in right.

Temporarily move the fsuipc.ini from the <sim root>\modules folder and place it in the <sim root> folder. Run the sim. My bet is that the engines will not fail. In which case, it's an FSUIPC issue.

If you have a phantom axis (something like a gamepad axis) assigned to the mixture 3/4 control, it could be spiking and momentarily setting mixture/fuel shutoff to 0, which would shut down the engines.

 

Go through all your controls in FSX/P3D and make sure that the sim has not auto assigned any axes you didn't intend, and then look in the calibration tab of FSUIPC to see if any of your control axes are making an input to the mixture axes.
