Your question was cut short (cut and paste does this sometimes). If your question was that the formula in the explanation for NGM should read NGM = NAM x (GS/TAS) then you are correct. I have corrected it in the databank and the changed version will appear after the next update cycle.
All the best.

Why don't the specify if they want the range in NAM or NGM ?
Or must we assume with a question like this they always ask for NGM?? How can I know...

Thx JJ Jones. Sorry I copied not all but I cannot retrieve the question or its number. Just remember it was a matter of knowing whether they used NGM or NAM in that question. So we will leave it for now. (The formula NAM to/from NGM is clear to me.)
