Ok, slight misunderstanding in my original post. I wanted to compare
the cost of a "flight recorder" now to a barograph then using 2008
dolar values. What was the cost of a new Barograph 20 years ago? Haw
does it compare to a Colibri, ect. in todays dollars? Is the entry
cost so much different? I'm only talking about the cheapest IGC
approved recorder solution.
