Realism, whats missing?

Aircraft weights. Specifically Max take-off weight. This is the maximum weight at which the aircraft is allowed to takeoff.
Lets take a look at the SBD-3. (I am referencing the pilots handbook)
The maximum takeoff weight fro an SBD is 9,519 pounds. A combat loaded SBD-3 with a 1000 pound bomb and 100 Gallons of fuel is 9031 pounds. Max fuel for a combat loaded SBD is 260 Gallons.
So technically with a 1000 pound bomb you should only be able to take about 40 percent fuel. Maybe 50 percent. Anymore than this and you shouldn't be able to takeoff.
Its like this with all planes. If you add weight(bombs and rockets) you have to make a trade off(less fuel) to prevent exceeding max weight of whatever aircraft.
Currently the game will let you take a max fuel load and fully loaded down with ordinance. (Watch all the new guys attempt carrier takeoffs with fully loaded corsairs)
So is there perhaps a way for the game to limit you fuel depending on what loadout you take?
