I am setting up my Saitek BIP panel to indicate to me when my fuel is running low and critically low.  I fly many different aircraft so I would think it would be best to set it based on percentage and not gallons (or pounds).  This maybe is also subjective?   What would you suggest I should set the two indicators for?  Not looking for perfection.  My first guess was 25% and 15%?

Thx for any input.

Does the front end for the Saitek BIP panel allow scripting? If so, something more "concrete" would be how much fuel is left versus time.
This would work for any aircraft regardless of # of engines or how much fuel is carried. 
 

<Update Frequency="1">

	(A:FUEL TOTAL QUANTITY, gallons) (A:ENG1 FUEL FLOW GPH, gallons per hour) (A:ENG2 FUEL FLOW GPH, gallons per hour) (A:ENG3 FUEL FLOW GPH, gallons per hour) (A:ENG4 FUEL FLOW GPH, gallons per hour) + + + 0.0001 max / sp1

	<!-- Both require power supplied to the cockpit panel -->
	<!-- Caution, between 30 minutes and 10 minutes of fuel left -->
	0.166667 0.5 l1 rng (A:CIRCUIT GENERAL PANEL ON, bool) and if{ 1 } els{ 0 } (>L:Fuel_Caution, bool)
	<!-- Warning, less than 10 minutes of fuel left -->
	l1 0.166667 &lt; (A:CIRCUIT GENERAL PANEL ON, bool) and if{ 1 } els{ 0 } (>L:Fuel_Warning, bool)

This depends a lot on the aircraft. On the 767-300ER e.g. the low fuel cautions come on at less than 3% remaining fuel. 

Thx for the reply guys.  I am setting it up through SPADnext.  It does allow for some coding but I think it is all "pre-programmed" to make selections like conditions and actions user friendly (which it is).  Spokes2112 I do not recognize the code.  Is that xml or sort of a psudo to explain what needs to be done.  Basically one can select a condition using FSUIPC or Simconnect like TOTAL GALLONS <= _____  so I was thinking of a percentage just to get me started and further from there.  I may be able to set this up per aircraft type but want just something to work so I understand.  Trying to determine what represents percentage in FSUIPC or simconnect.

It is a snippet of of gauge XML.

With that example it looks like you will need to know the total gallons available and do the math yourself for the trigger percentage - per aircraft. 😞
There is one way to get a global annunciator across all aircraft but I would have call it "advanced".
1)  Write a .lua to do the calculations using FSUIPC (must be registered) and writing the results to user available offsets. This could include both percentage remaining and/or time remaining.
2)  Modify the SpadNext file: "FSUIPC Local.xml" so it will tell SpadNext where to look in the FSUIPC offsets to obtain the lua produced values. This will also add an easy user interface to use within the SpadNext program. ( reference )
3) In the SpadNext program you would then use the selections to use any of the possible, as examples -
FSUIPC Fuel Time <= _____
FSUIPC Fuel Percent <= _____
etc..

I don't have SpadNext but have done some other projects during the now expired 14 day trial.
This may be a perfect project during the morning coffee over the next few days.. ☕
Interested?

Yea, I'm gonna mess with it over the next few days in my spare time see if I come across anything, but if you also find it a nice little challenge I welcomne all input.

Happy Holidays

Happy Holidays to you too!
A little kit is finished, available here if you haven't had any luck with SPADneXt direct fuel values.
The lua itself is tested and working fine (since Sunday) all it took was a readme.. ( for me, the real difficult part 😠 )
If you use it, hope it works well.

Hey Roman,

I clicked on your link but all I see is a blank dropbox page... no file?  

I was able to obtain some xml code that works pretty good based on percentage of full quantity.  I was unaware that one could drop in xml code right into SPADnext so that is convenient.  Now I want to try setting up for individual tanks (left, center, right, etc.), so I still want to see your code.
