When I access the weather information page (Not the weather map) it displays both the raw and translated text for the METARS and TAFs at the same time. Now this is ok, but if there are several sites in the "report", it can be several pages long when both the raw and translated text are displayed. Personally, I think most pilots are pretty good at reading the raw text in the METARS & TAFs and I actually find it a lot easier to absorb the information in the raw text. There are some occasions when you need a little help with an obscure abbreviation but for the most part, I think most of us do well enough with just the raw text.
My suggestion would be to add a radio button to select how the user wants to display the METARS & TAFS. For instance "Raw", "Translated" or "Both"
