I got this many years ago. It's essentially the Pilot Charts
and a rudimentary weather-routing package using simple polar performance data. It might give you a reasonable first cut at a potential route
, and will tell you what the conditions might be along the calculated path.
It knows *nothing* about actual weather
, just the historical average pilot chart data, so you will probably find that your actual route
and speed will be significantly different.
I would consider it an interesting sanity check for a proposed passage
, but not much more than that. It's educational, but not all that practical.
