Engine Start Failure - No oil pressure

[jfuenmayor]

Hi Guys:

First,  many thanks to Sam and his beautiful family for a wonderful time
in Sarasota. It was also a pleasure meeting all of you guys. It felt like a big extended family.

About the problem with starting the engines and lack of oil pressure, I do not know if you guys
had the time to address the issue, but after returning home, I ran some tests in my Sim, and sure enough, I experienced the same problem, and it seems that it has occurred to many others as well. And it is with Prepar 3D v3 and FSX as well, and the ProSim aircraft model.

It seems that there are some conditions that trigger the lack of oil pressure and engine start failure, it may occur with a change of airport after shutdown or if the aircraft remains with engines off for more than 20 minutes. Anyhow, this file seems to solve it.

The file is a modified "panel.cfg" file that goes in the /Prepar 3D/SimObjects/Airplanes/Prosim 737-800 Regular/panel/. It is posted in the ProSim Forum. Anyhow, I have attached it for simplicity.
It is a text file and some modifications have been made. At any rate, the program runs as usual.

I suggest you backup the original file before overwriting it with the new one.

Cheers

Great find! Thank you Joaquin I'll try it to see if it changes.

Hi to all again:

After some more testing and leaving the engines off for one and a half hours, the problem returned. It certainly is a strange behavior. Yesterday evening all flights with intervals of about half hour had no problems. Today, I switched scenery from Paro  VQPR( Buthan ) to KMIA, Gate F11, left it there on GND PWR for one and a half hours, tried to start, and again no oil pressure.

This is beyond me. It is definitively a bug of some sort. Whether it is ProSim or P3D, beats me. The only way to restart is to close all clients, Prosim and restart P3D. What a pain.

I will continue to search.

Joaquin.

I have a similar problem if Prosim is left idle for more than about 20 minutes. The engines usually start but then there is no engine sounds, I have to load a saved scenario with engines running then flick back to where I was and this restores the sound. Another bug is the wet compass which loses half the display when flying due east, many report having this issue but I plan to build a mechanical compass at some stage. Certainly not complaining about Prosim though, it is by far the best 737 software and a joy to use! Cheers Gwyn

Thanks Trevor I will do more West and adopt tacking techniques for going East!!

Tacking techniques is for sailing bud not flying. Ha ha ha ha. Sorry I know this was not productive but it was fun anyway lol.
