Recently started flying the NGX  600/700 expansion after installing it in P3D4.1, and encountered a strange issue:

After apparently normal startup flow from NGX SHORT, when I advance throttles above idle to start taxiing out, the left engine suddenly fails.  Yellow ENG FAIL warning on EGT display. and low oil pressure.  Yet the PMDG SETUP\AIRCRAFT\FAILURES, shows no active failures.  Service based failures are off.  Performing maintenance doesn't resolve the problem.

I've also tried loading the NGX DEFAULT panel - with engines already started - but get the same problem.

Have seen this behavior with both the SWA N940WN and the UAL N17730  B737-700 WL liveries

Have never encountered this using the B737-800 versions.

Any idea what the cause is and how to fix it ?

 

Hi,

Can you check whether the fuel flow drops just before the engine fails? If yes, I would suspect something with the fuel mixture be assigned to one of your hardware axis/button.

Thanks Budbud - Indeed I had dual FSUIPC axis assignments.  Problem resolved.

You are welcome.
