I meant to ask you... what's the procedure for flight into the teens in this thing?  I think the power settings in my pic are too high (I wanted to go fast).  What would be more suitable for 75% power?  Like 30 / 2700pm?  And then with the turbochargers do you still lean out at 17,500 to the 75% power range on the fuel flow gauge?

Yep, those power settings look high at ANY altitude! 🙂  IRL, you'll pay for that in engine costs and longevity.  Don't know what Black Square's algorithms will make of them though.

Remember that in a turbocharged airplane with an automatic wastegate, the settings for x% power will be roughly the same regardless of altitude up to the critical altitude (with some small variations).  So, for example, on an ISA standard day, the book gives recommended power settings of 31.9 inches of mp and 2750 RPM for 75% from sea level up to around FL220.  That's what I typically use, with some adjustments if temps are dramatically warmer or colder.  Note, I rarely fly the piston duke above FL240 due to diminishing returns and the limitations in cabin pressurization.  I fly even lower mid-summer.  My passengers don't want to hear that they have to don oxygen masks!

As for leaning, I don't use fuel flow.  With the JPI EDM-760 and it's "Lean Find" mode, accurate leaning based on EGT is a breeze and far better than the approximation you get with FF.  I've never found detailed info on leaning for the Grand Duke (if anyone knows of a source for the Grand Duke POH, I'd love to know about it) so I lean about 25d ROP once I reach cruise.  And again, up to the critical altitude, FF should be mostly unchanged at those settings.

Does anyone happen to know if these are compatible with SU4 beta?

I've updated all of my liveries now - please note this was a pain in the rear.... probably took a good 8-10 hours to update all of them.

Thanks for updating your paints!   paintin' ain't easy, but it sure is fun. 👌

Hi Ryan,

 From sea level up to FL200 75% power is 31.9 In MP at 2750 RPM. Fuel flow should be 133 PPH per Engine which should net you 241 KTAS in the Grand Duke, and 225 KTAS in the stock Duke.  Same settings lower will give you 217 KTAS in the Grand at 10,000 feet and 198 KTAS at sea level again in the  Grand.

Climb to FL 240, and increase the throttle to 34.1 in MP with the same 2750 RPM for the same fuel flow of 133 PPH per engine but at 250 KTAS in the Grand or 234 in the stock Duke. 

Above FL240 you loose ground, so avoid it unless you are climbing above weather. FL300 at 29.3 in MP and 2750 RPM will save fuel, at only 104 PPH per engine but your TAS drops to 243 in the Grand and 227 in the stock Duke.

Recommended climb speeds gettin you up there are 140 KIAS from sea level through FL200, 130 KIAS through FL250 and 120 KIAS through FL300

 

 

Power setting charts can be found on Page 74, 75 of the  Piston Duke Manual.

Thanks for the detailed response.. I guess I had forgotten this 😂

I haven’t tested every function and feature, but the turbo Duke at least seemed to behave normally when I used it yesterday. 

I just hopped in the Turbine Duke for the first time since the update yesterday and enjoyed it once I got up in the air. Getting set up for the flight reminded me of why I sometimes get tired of Black Square products, though: the checklist is so mind-numbingly long. Especially for a multi-leg flight (e.g., land, shut down, walk to the FBO for lunch, then start up again and fly somewhere else), I suspect that it wouldn't be realistic to run through the entire list of pre-takeoff checks for every single leg of the flight. 

What would be a realistic way to handle this which is true to life? I know there are checklists out there on flightsim.to which label the essential items for just getting going, but are there any that give guidance on how often each systems check should be done?

Personally I try to memorize pre-takeoff checks into groups.  For example (piston Duke), run up to 2000 rpm and do the electrical stuff (mags, generators) and props.  2500 pressurization tests, then back down to 1500 for the rest (de-icing switches).  This way I don’t have to memorize each specific checklist item, and I can fly through everything in maybe 5 minutes or less.

Does the free PMS50 GTN 750 work? I've downloaded it and extracted to community folder. But I can't get it to show up using the tablet. Default GNS530 works.

Yes, it should work fine.

Hmm, does not here. Anything else what I have to do? I open the tablet, choose the GTN 750 as primary. Confirm. But nothing happens.
