There are two compatibility tables. One for cargo-cargo compatibility and one for cargo-tank compatibility. A green bullet means that the two are compatible, while a red bullet means that the two are incompatible.
Cargo compatibility input
Indicades if loads are compatible with each other. Please note that a load is always compatible with itself and that if load A is compatible with load B, then load B will always be compatible with load A.
Tank compatibility input
Indicades if cargo is compatible with a specific tank.
