I agree, why traces are needed is really the point. But I believe a GPS with
WAAS is far more accurate than a barograph and should also be more cost
effective. But unless someone seeks approval then I would not expect any
specification to change. I was just wondering if there is any movement in
this area.

I don't think it happens quite that way. If you submit a recorder that
does not conform the Specification in Force at the time, approval will
not be granted until it DOES conform. The specification would need to be
changed FIRST.

I do not believe that the requirement for Barometric Altitude will be
removed any time soon.

As opposed to NOT approving a recorder which does meet the
specification at the time and then changing the specification later?
Which GFAC has done.

I agree, that would be far too sensible a decision for IGC/GFAC to
make.
