So the value for a3 wouldn’t be a calculation, but rather a point taken off a chart.
I’ve included a picture of the chart for 88-2, and you can see below 2A, the value is 33.1.The value for A3 is just a defined number that is a combination of type and rating.
On excel would it just be a case of putting all the values into the sheet somewhere, so you could say if a1=88-2, a2=2A, a3=z1 (z1 being where the relevant figure is recorded somewhere on the sheet).

It's definitely possible (although realistically most stuff is in Excel depending how much effort you want to put in).
This may be what you're looking for with the drop-downs

Not quite sure where A3 is coming from, whether it's a formula or an existing set of data or something.
And something like this for colouring your cell red
