I've been tinkering with the PC-12 sounds the past few days, inserting some of my own recordings from the actual aircraft, to make the Carenado feeling a bit more realistic.  I increased the volume a bit on the fuel pumps to see/listen to their behavior some before inserting my own sound.  Perhaps it's just my system, but for some reason, with the pumps in the "ON" position, it sounds like the pumps only operate for 2 or 3 seconds, then shut off for 2 or 3 seconds, then turn back on.  The actual aircraft, they should be continuous for as long as they are "ON", not a strange oscillation like I'm hearing in my sim.  Does anyone else have the same issue?  I know the default sounds are hard to hear with background noise but I'm just curious if it is indeed isolated to my system, or I need to find out how to have the pumps operate continuously in the sim.

 

Thanks.

 i checked the fuel pump sound and experience the same behavior as you describe

 the sound is not continuous, more a periodic activity

 as i have no idea of how it should work inrw i did not bother...

Yep, they should be continuous for as long as the switch is "ON" rather than "AUTO".

 

Any of the smart XML gauge programmers out there know how I might be able to change this?

I've looked into this and there's an error in the xml gauge coding by Carenado.

 

The fix is simple:

 

Open gauge_update.xml in your ...\Prepar3D v2\gauges\GaugePC12 folder using a text editor. Scroll to line 292, change:

 

els{  (A:GENERAL ENG FUEL PUMP SWITCH:1,BOOL) 0 == f{ (>K:TOGGLE_ELECT_FUEL_PUMP1) } }

to:

els{  (A:GENERAL ENG FUEL PUMP SWITCH:1,BOOL) 0 == if{ (>K:TOGGLE_ELECT_FUEL_PUMP1) } }

 

As the "if{" operation is mispelled, the fuel pump was cycling instead of staying on until you click the switch again (sending a toggle command).

Great catch, thank you!
