Hello,I'd like to make a fuel transfer pump to pump fuel from the aux to the main tank for example, with FSBUS CCC.My idea is to assign a taster switch to a timer linked to a counter which substract gallons from a tank and add it to another, repeated every seconds till the tank is full or the other is empty or if the switch is set off.That's quite lots of conditions to solve ...Therefore the fuel is coded in capacity (%) and not directly in gallon, as the tanks are different size, we've to calculate the fuel quantity in gallon by multiplying % and total gallon, I don't know how to do that with fsbus ...If someboy have ideas or propositions ....Thank'sBOB

Hi BOB,sorry the Add/Mul will not do the trick with fuel quantity but why not, instead of thinking in gallons, thinking directly in %.The total capacity of each tank in your aircraft is fixed. You can calculate the relationship between a % of one tank compared to a % of another tank. Let's take an example: the main tank has got a 100 gallon total capacity whereas the aux tank is only 50 gallons total. 1% for the main tank is equal to 2% for the auxiliary. Using the Multiplying property of the Add/Mul object you can multiply by 2 the FS input of fuel aux tank then add or subtract to the FS input of fuel main tank...Hope it will help,Francois

Unfortunately in the current available router software it's just the counter that does not work :(

Thank's Fran
