I uploaded my first iteration of my Checklist for the Turbine Duke.

Awesome thanks!
THANK YOU! I’ve never created a custom script but seems I figured it out. Copied your code in AxisAndOhs and it seems to be working. Thank you very much!

For some odd reason after I reset the altitude preselect and hit ATT it went into GS mode. I adjusted the pitch via the wheel and it works as if it’s in ATT mode. Further adjustment of the wheel flashed ATT with GS still lit. Am I not doing something right here? I found this but it doesn’t make sense to me why GS mode would engage in this instance.
do you have all avionics (such as pms50) up-to-date ? someone reported CTD related to FSUIPC. I don’t know if it s related …
if you still encounter issues, it maybe useful to try with a clean community folder to exclud other mod conflicting.
I also saw someone fixing some error he had by clearing his game cache
I had all sorts of problems last night trying to start the engines on the Duke Piston.
I’m guess it’s:
-1% change the plane has bugs
-9% chance it’s controller mapping errors (I have the mag switches mapped to my Logitech Switch Panel, and repurposing the AutoThrottle toggle switch to select L and R engines.
-90% change it’s a “Read the (Fine) Manual” issue 
Will be Away From Sim for a couple of days, so will spend some time going through the doc, as there’s got to be lots of important stuff buried in there.

"I did some testing and I found something weird.
I redownloaded the latest GTN750 version, installed it and as I would normally launch the simulator with FSUIPC running, I did not this time.
Now I can load a flight without a CTD.
Then I quit the simulator, launched FSUIPC, launched MSFS again, and again after pressing fly now a CTD occurred.
Now here comes the weird part.
I started up the sim without FSUIPC running. Loaded up a flight and after the initialization process I launched FSUIPC, BUT NOW WITHOUT CTD.
thats some weird stuff,no?"
Hi,
I use FSUIPC7 to be able to feather the props in light twins and also with the Dukes.
BUT, I launch the Duke in MSFS first, and only after the plane has loaded, I start FSUIPC. Never had a crash doing it that way.

Yes, me too. It took me about 10 to 15 minutes (can’t remember exactly) to fire up both engines.
I was using live weather though, siming at EGNM (Leeds UK) and it was a very hot when I was siming. I was using the standard cold start up procedures though and I think this could possibly be the reason for my start up problems.
Love the aircraft but have a question regarding the pressurization of the turbine Duke - it looks like if you go higher than FL240 you will exceed 10000ft cabin alt. Is this true
for the actual aircraft. I’ve done 2 flights no higher then FL220 but the fuel burn isn’t as good.
I have not had any problems starting since I watched this video

Yes that’s expected. You can see it when you move the pressurization wheel to 28000 feet, it will show you that expected will be 12 000 ft cabin altitude. It’s legal but not very comfortable for passengers, so you might as well turn on oxygen so they can huff it on-demand to get those oxi numbers up 
(and this actually really works in the plane).
You can stay at 25k where it’s close to the more comfortable 10K, there isn’t really much use flying at 28k when you look at the performance tables.
“there isn’t really much use flying at 28k when you look at the performance tables.”
But I’m doing it anyway as I write this - better fuel numbers.
Thanks for the info.
Your fuel flow is better, your true air speed is faster yet your range is less than at FL250 huh?
How does that work?
Right now using the FL280 power setting of 840TQ and 1800rpm I’m getting 31GPH
per engine at FL280.

Hi,
My guess would be that at FL280 you would be above the optimum altitude.
Your angle of attack would be higher just to maintain that altitude. With a higher angle of attack the drag world increase, resulting in less range.

I understand what you’re saying but surely even if an object is travelling vertically if it is producing better fuel flow and a faster true air speed it should still have a longer range?
More drag would create higher fuel flow to achieve that speed?
- Not a physicist👩🔬
Yes, but not only that. The engines would perform better at higher altitude, but it is the wing which has to provide the lift to carry the weight. To obtain the required lift, the angle of attack needs to be increased as the air gets thinner the higher you fly. Eventually at some point the angle of attack will reach its critical angle at which the wing stalls. This is known as the coffin corner.

A rock travels at TAS 253 FF 28
Another rock travels at TAS 263 FF 27
Which rock will have the longer range?
All other considerations shouldn’t matter???
The most important figures for working out range are already stated?
Drag & friction would only be factors if they had an effect on fuel flow or speed which in this case it does not.
Not saying you’re wrong at all, just trying to make understanding of what you’re saying.
Surely any effect of drag would make itself shown in the fuel flow or TAS figures which it does not
I guess that’s a more elegant way of putting my question
