Hi!

I have 2 issues in P3Dv4, which may be related. During the preflight checklist, on the last item "Engine Start Levers", I say "Cutoff" and the FO always responds "Are you sure?" then says preflight checklist complete. The engine start levers are of course cutoff.

On starting the engines, I start engine 2 first. Once its started, I command the FO to start engine 1. He clicks the starter switch to GRD to start the engine, then immediate begins acting like the engine has already started. He begins his before taxi procedure before the N2 on the engine has even begun to ramp up. Because of this, he turns the engine start switch to CONT, turns the packs to AUTO, turns off the APU bleed and the APU itself, tries to put GEN 1 on the busses although the engine hasn't started, and blanks out the bottom DU. This causes the engine start to fail as its lost the bleed air it needs to start, and I cannot even get to the point where I need to move the fuel control lever to idle detent.

Any help here would be appreciated!

 

Thanks,

Chris Lezama

Hi Chris,

This be your solution here:

Question: During engine start, the FO says "STARTER CUTOUT" way too soon and starts his after engine start procedure before I even started the engines.

Answer: You have a button or hardware lever assigned to the FS "MIXTURE CONTROL" command/event.  Delete that.  FS2Crew reads the position of MIXTURE CONTROL to determine the position of the Start Levers.

That did it. Thanks!

This is the Exact thing that was happening to me I’m going to try that out also

I deleted all of the mixture controls for all my hardware and i'm still having that issue, Any solutions?

You didn't delete all of them or they're still there somehow.

The issue is 100 percent related the MIXTURE CONTROL event.

Check again.

Cheers,

 

I have not had this issue until recently why are we having to delete mixture control many of us use it for our GA planes and why has this become an issue, I can't use it to move the fuel cutoff levers (saitek pro flight with throttle quadrant) I hope someone has more of an explanation. thanks

The PMDG 737 was actually built around the default Cessna 172 in many respects.

I'm not making that up.  

PMDG connected the fuel levers to the mixture control event in FS.  That's why.

Cheers,

You may not actually need to delete the mixture controls, but if you are having the starter cutout issue you will need to calibrate the axis for mixture.  I recommend setting sensitivity to maximum and also set a dead zone.  Try about 5 for a dead zone to start with.

I would also recommend the same calibrations be carried out for throttle and prop axis.  .  This SHOULD solve the issue.  It did for me.

Thanks for the tip 🙂

I have to take back what I said in the post above, because recalibration of the mixture axis does not seem to be solving the issue in Windows 10.  This worked previously on my Windows 7 setup, but since I got a new PC early January I have had this issue and don't seem to be able to solve it without completely removing the mixture axis.

Driver issue?

 

Hi Bryan,

 

I'm not sure.  I think all my drivers are up to date as I did that when I first got my new PC set up.  I have been flying the Airbus lately, and haven't been in the NGX for a litle while.

 

Cheers,

I see nothing that is specifically "Mixture control" though there are 4 other Mixture related entries such as "mixture lean quickly" etc. Should I be deleting all of those?

Aaron,

Are you using FSUIPC?

Just delete your Mixture entries.
