Could some native speakers explain to me whether it is possible to use plural nouns attributively? I am writing an essay in a very technical field (aeronautics) in which I need to use contracted forms to avoid too many redundant sentences.
I would like to know if I can use this expression "wing tanks fuel" to express the concept of the fuel contained in the wing tanks of an aircraft. Should I perhaps use the genitive? Then my expression would become "wing tanks' fuel"? But I am not at all convinced that this is the right solution.
