744 QOTS 2 Electrical Issue

Recommended Posts

Has anyone had an issue with, after engine start, your APU Gens will remain in the ON position and not automatically switch to the AVAIL position? If I turn off the APU or the generators after engine start I lose power to the aircraft. With the engines running I have also seen the warning message the engine generators are not on, but with I look at the electrical switches they are normal.

To try and figure out the problem I have gotten rid of saves, all my panel states, leaving the default. I have loaded fresh. selected the 744 default state that comes with the aircraft and the engines are running. I shut them down to test and relight then as normal procedure I use. They generators turned off automatically. So I shut everything down to plan for the flight since the test worked. Once I finished planning the flight and pushed back, it was back to the same problem. I have messed with different scenario with a friend who is having the same problem for two hours and am still having trouble. It is like there is an issue with the engine generators, but loading fresh is not fixing much. 

Let me know if this is a known issue and if you know what the cause is?

Thanks,

Josh

It's not something I've ever had happen consistently, but I have had situations occasionally where one generator might not kick on for some reason. I'd click the switch off and back on again, and that normally solves it.

I gave that a shot on all 4 and that did not help. Thanks for the reply. I will keep trying to solve this issue and I will post if I figure something out.

This hasn't come up in two weeks, folks are learning that you need to may need to bump the throttles a little after starting to bring the generators on line.  This is due to your start not having sufficient flow for a complete start... low duct pressures maybe?  Turn off packs before starting?

I start engines 3&4 and then 1&2, all with all three packs off, yes. I will try to bump the throttle. I just think it is strange I have used the same procedures since I got this and am just hitting this problem. Only other thing different is I have updated my Aerosoft Anchorage X scenery to show correct runway's and now I am having this problem. I am going to undo that update and see what happens. The scenery shouldn't mess with it but with FlightSim anything is possible to break something lol.

You are not doing anything at the end of your flights like a passenger evacuation that will trip all the fields, and then the next flight the fields are all open? Just a thought...

Have you tried different engines? What was the outside air temperature? Looking at the manuals, at super low temperatures, the idle speed of a particular engine type may get close to the speed at which the GCB is allowed to close.

If in doubt, submit a ticket. :wink:

Thanks for the help everyone. It is truly appreciated. Here is what I found out.

My PANC scenery from Aerosoft, the Anchorage X scenery, the runways 33 and 15 were different. They were changed sometime after the scenery came out to 33 and 15. So my friend found an update from Aerosoft that changes the runways to the proper designation, 33 and 15. We both had the issue, and never had it before installing the scenery update. During our 2 hours of testing, my friend loaded up at a different airport and it worked as it should, so I uninstalled the PANC scenery and reinstalled the Anchorage X scenery with the old runway designations.

For some reason, the update to the PANC scenery and the QOTS 2 did not get along. Once I got rid of the update to the PANC scenery and installed the original Aerosoft's Anchorage X scenery, I loaded up my saved flight, and it made the transfer flawlessly.

It makes no sense to me why the scenery would mess with the engine generators, but like I said before. With flight sim, ANYTHING can break.

Thanks again for the help!

Okay, so new question. If you were to have the update installed, but you disabled the scenery, does this problem still persist. I'm just curious here.
