Help!
I’ve got a red ‘H:M’ flashing in the engine management thingy.
What does this mean?
thanks
Hours:Minutes
Why it’s red, I don’t know.

Thanks.
I can’t imagine either.
Sometimes these aviation acronyms are just overwhelming…
You’ve set the fuel differently in there from your actual load and it’s telling you that you have no hours or minutes of fuel remaining.

Exactly!
After each refuel you need to “tell” the device what the current fuel quantity is.
For example: if you put in 30 gallons, subtract the remaining quantity and put that into your JPI.
You also can do it the easy way by pressing the “update digital engine monitor” on the fuel/payload screen on the EFB.

I believe there is also a button on the tablet that syncs the current fuel level with the JPI.

I’m a newb with these things. Please tell me how I might have done that?
Thanks
I’m gonna be honest - I don’t know how to set it, either! I need to RTFM on that one, haha.

I’m having a little trouble understanding the relationship between adjusting the wieght of the plane via the table and the FS2020 weight adjustment fields.
I noticed that the fuel levels will match between the Tablet and FS2020 window but the weight and weight distribution doesn’t!
I also noted that the CoG slider in fs2020 window will allow you to shift the CoG of the plane but that doesn’t effect the CoG reading in the Tablet but you can feel/see the CoG being shifted!
So is there a way to link the data between the Tablet and FS2020 window or if not, what is the correct way of using it?
And how does this all work together with AddOns like NeoFly?
I just do it the easy way, which is to hit the Sync button in the fuel/payload tab in EFB. Forget exactly what it says, but it’s the longer button on the bottom of that tab.

"Why can’t I change the fuel quantity in the default weight and balance menu?
Accu-Sim includes an external simulation of the Lycoming O-540 engine and its fuel system, including removable tip tanks. For the reason, the default fuel system isn’t supported, and you must use the fuel/payload page of the tablet to add or remove fuel, passengers, and baggage."

The default weight and balance tables have no effect on the Comanche. That’s what the tablet is for. 
Yes that’s the reason but it’s not a good enough one. They should be able to use the sim supplied method for setting fuel and allow communication both ways to/from their model. It seems to only be one way but it should be a 2 way thing which would allow you to use whichever method you choose. It’s not a standalone sim it’s an aircraft designed to work within the framework of an existing sim. I commend A2A for the quality of the aircraft but it could be better when it comes to sim integration. This and other integration things need improvement.

How does the EDM-830 know the fuel levels are different?
You set it for a certain amount of gallons, it calculates how much time you have remaining based on current fuel flow.
If I set it for 5 gallons, but actually have 20 on board, then fly for 30 mins at 10GPH, it’s going to read zero time remaining, even though I still have 15 gallons (1hr 30m) remaining.

A fuel computer function of which you find in the EDM uses fuel flow to do its calculations. The idea is that you have an independent means of monitoring your fuel levels to the basic fuel quantity indicators. Older aircraft like the Comanche generally have low quality fuel qty indicating systems so having a fuel computer is a more reliable means of monitoring and more importantly it gives an independent source for fuel management. The two systems are not connected in any way and share no data. For a fuel computer based on flow to function correctly it needs to know what you start with so every time you add fuel you need to tell it what the new total fuel remaining is. Depending on the fuel computer model you do this in slightly different ways but entering what you just added is a common way. The fuel remaining value and other associated calculated values then change according to the measured fuel fliow. None of this takes away the need to visually inspect fuel levels but it’s another source of information and totally relies on correct entry of fuel by the pilot.

I disagree. I find the MSFS clunky at best. Any time I change anything on the page it resets everything (usually inaccurately) to 50%, and getting it to accept 0 weight for the copilot is problematic at best. If A2A can supply a better solution I’m all for it. If the MSFS version ever becomes reliable I may reconsider, but at this point, I’d much rather have a reliable external source, than an unreliable internal source.

My feeling too
Two ways that I know of. One is on the tablet, where you set fuel. There is a “sync” button right below those controls.
The other is on the engine management computer itself. It will pop up asking you to set fuel, and the left button cancels that option. The right button toggles between set amounts, but you can also increment/decrement single gallons too.
It doesn’t know the values are different. It thinks you’re running out of fuel which is why it’s throwing the error for the pilot.
