Empty Weight: 9060 kg
Max.Weight: 19500 kg
Internal Fuel: 4000 kg
it makes a good sense to take weight as 4000 kg. max weight is a conflicting figure.but even with taking lowest figure of max wt(19500)
the ratio is 0.20.
range really depends upon the configuration used.the engine efficiency and speed of flight will be big factors.but the higher fuel fraction for su30 surely wont stop it from getting the good edge in range.
