Nope, you can't get Obs Planes with that recipe. Those seaplanes are in the steel/fuel result table, therefore " / ≥ " has to be true for the recipe. The biggest input in your recipe is bauxite, so Obs Plane won't appear with it.

If you want Type 0 Observation Seaplanes, use either 20/10/10/20 or 10/10/20/20.
