Well - there's a thing -as a non SSA UK pilot for years

Chris,

Thanks. That's a good archive site that I knew nothing
about - and it gets me back to what I could previously
access.

I still feel that it is a shame that the SSA have decided
to deny general web access to all of the Johnson tests
at the time they have posted some more recent ones.
The are a unique resource of independent data.

No polars are ever going to be totally true but Dick
Johnson has a record of picking up quite few valid
performance issues over the years. DFVLR polars are
surprisingly smooth, surprisingly better at higher
speeds than Johnson's, don't show individual flap polars,
and are available only by individual purchase 2 years
after measurement or in manufacturers manuals. I always
use Dick Johnson's data (if available) for glide computers.
