Why not a gauge who meters the flow of fuel to the tank, and computes this= flow against the know quantity of fuel on the tank? If the flow is 3= gallons/minute, and the tank has 30 gallons, you have 10 minutes of= flight. It is just a matter of counting how much fuel has passed thru the= flow meter... It cannot be as simple as that, but I cannot see an easier way ---8<---Corte aqui---8<---- Alexandre Souza taito@terra.com.br http://planeta.terra.com.br/lazer/pinball/ ---8<---Corte aqui---8<---- -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
