Hallo,Is it possible to show (in a string) the decrease in total weight e.g. (A:Total Weight,pounds) in time (Minutes) WITHOUT using the fuelburn variables?I am looking for a value showing the average weightdecrease/time.Jan"Procul Negotiis"

Jan, This works.. Keep in mind it will only give the AVERAGE.Difference in weight divided by difference in time.******* RESET / LOAD BEGINNING VALUES ( load once )******(G:Var1) 0 == if{ (P:Absolute time, minutes) (>G:Var2) (A:Total Weight, pounds) (>G:Var3) 1 (>G:Var1) } *********** DISPLAY **********************%((G:Var3) (A:Total Weight, pounds) - (P:Absolute time, minutes) (G:Var2) - / )%!d!% avg lbs/min%*********** RESET ************************* 0 (>G:Var1)Regards,Roman

Roman,Thanks again!The code gives me a useful number which i want to use for screening for icing and fuel jettison. JanNot so "Procul Negotiis"
