Context: XP11.40 with Carenado PC12 HD Series XP11 with Simcoders Reality Expansion Pack

Successfully created Aircraft Performance file for PC12 in LNM using standard aircraft performance data and Fuel Type 'Jetfuel'. When I create a new Flight Plan, LNM shows Fuel Type as 'Jetfuel', which is correct.

When I fly the sortie, the Current Performance tab shows Fuel Type as 'Avgas'', which is incorrect.

Have checked online manual and understand from paragraph 35.2.2.2 that Fuel Type is reported by the simulator.

How do I: ''Correct this manually if add-on aircraft do not provide a correct fuel type''

Not sure if this a Carenado or x-Plane issue because it doesn't appear possible to change it manually in LNM.

Thanks for your help.

 

Hi,

simply use "Aircraft" -> "Edit aircraft performance". Then go to the tab "Performance" and change the fuel type on top. This meant by correcting it manually. Check the numbers afterwards if they are still correct. But this will not fix the wrong reporting from the simulator.

Not sure why the PC-12 reports the wrong fuel/weight ratio. Does not make sense for this aircraft.
Some special planes like the DA-62 which is a piston actually consuming jetfuel do report avgas. Understandable there due to simulator limitations.

Hi Alex

Thanks for your suggestion. It sounds like its an aircraft report issue. I've taken 2 screenshots that show the Fuel Report tab with Jetfuel and the Current Performance tab with Avgas for today's flight. I have overlaid the aircraft performance file on both to show it was set with Jetfuel.

It doesn't appear that I can attach the png files on this forum.

I'll take it up with Carenado on the x-Plane forum.

Hi Norman,

you can ignore the wrong report on the current performance tab after changing the fuel manually to the correct type.

But I'm not sure what happens in the simulator if the aircraft has the wrong fuel type. The fuel type for PC-12 it should normally be clear and not require any workarounds (like the DA-62 with its diesel engines).

Hi Alex,

I'm working on this issue at SimCoders to fix the PC-12 fuel reporting thing.

Actually, in PlaneMaker I cannot set the fuel type nor I did change it before. What I did is change the engine type from the old turbine model to the new freeturbine model which is a more accurate representation of the PT6.

Could this be the issue? Could it be that if LittleNavMap does not recognize the new engine type, it falls back to a piston engine and so avgas?

Thanks!

Noted, thanks

I'm looking at the "sim/aircraft/prop/acf_en_type" array dataref which should return 9 for the new free turbine model.
According to a user this returns 0 for the PC12.
Additonally I'm trying to read the acf file and look for the engine type. If this starts with "TRB" its a turboprop.

The new engine model is already supported for a long time in LNM. No issues with the Carenado Saab 340B or the PA31 which also use "P _engn/0/_type TRB_FRE_n2".

What I forgot to mention:
Make sure to use the latest Xpconnect plugin. I fixed the new turboprop model already beginning of last year and I've seen people using stone age versions.
Latest Xpconnect is Version 1.0.18.

Hi Alex

Thanks for the advice to upgrade to latest version of Little Xpconnect. My bad for not spotting that issue. Everything now works fine.

I just checked. It returns 9 in my case. Moreover, REP does not write this dataref at all.

Maybe the user is running other plugins that overwrite this dataref?

In my experience, when dataref are corrupted this way, a clean XP install is the way to go.

X-Plane fills this dataref. There are plenty of those mirroring data in the acf file.

But anyway. Issue solved and could have been solved early by user reading the bold highlighted messages on top of the changelog a year ago.
