But the EW D is still an approved IGC recorder up to Diamonds, and National
Comps in most parts of the World (provided it is attached to an appropraite
Garmin so that the record shows it was set to WGS84).

Does the USA have different rules to IGC?

A few years ago one of these friend took his well maintained Schreder
sailplane to the Sport Class National contest. He is a skilled pilot and

placed in the middle of the pack. At the time his EW Model D and Garmin

were acceptable. For him to compete in the future he will be required to

invest between 10 and 20 percent the value of his glider and trailer.

What information is provided by the "approved" flight recorders that
cannot
be derived from a EW Model D?

It appears that this type of rule's only purpose is to keep people with
big
buck gliders from being embarrassed by a kid flying an affordable 40 year

old bird.
