Hi J-P,

First of all let me say the new training scenario by Claudio is awesome, he surely put a lot of thought and effort into it! This is the first time I tried a training scenario, and actually the first time I tried failures in general Hope there are lots more of those coming!

But I'm having some problem executing the NNC, and I'm wondering if I'm doing something wrong or if it's something else:

When I'm at step 5, I

• set the BUS TRANSFER switch and both ELEC HYD PUMP switches to OFF

• start the APU

• once the APU is running I switch the APU GEN switches ON (one at a time)

• => the SOURCE OFF lights always stay illuminated and I remain without power

But - if set the BUS TRANSFER switch back to AUTO before switching on the APU GEN switches (which is listed as the next step 10), then both SOURCE OFF lights extinguish and I get power back...

Why doesn't it work for me when I follow the steps exactly ? I'm using the 737-800 scenario, in case it matters...

Thanks!

Hi,

Many thanks for your message,

I just tried it again and both Source OFF lights extinguished.

When you start your APU, do you wait around 90 seconds for it to be available before switching the APU gen one at the time?
You need to wait until APU GEN blue light is on, was it the case?

Cheers,

Hi J-P,

thanks so much for your response! Yes, I did wait until the APU was fully started up, and the APU GEN blue lights came on. I made a little recording of what happens in my cockpit so that you can see yourself (it's already forwarded to when the APU GEN light is about to come on):

So if it's working for you (and I assume others as well) I would really like to find out what's the difference that it won't work for me. Could it be some PMDG or Sim setting?


Thanks!
