Glide ratio with full brakes and side slip

Charlie: could you explain what the "Snowbird" involves? (And say "hi" to my old friends at HHSC, if they're still there - it's been a long while!)

Energy management mostly.
Each flight covers 4 items together:
-precision duration (usually multiples of 15 minutes timed to the second)
-touchdown in marked zones, touching before 1st zone is a big point hit, touching further is lessor hits
-stopping at a cone, scored to the inch
-cumulative altitude gain

So, duration 5 seconds off, touchdown in prime zone (no deduction), stopping within 5" of cone and no altitude gain would yield a score of 990 points.
You're allowed 2 flights Friday and 2 flights Saturday, a good year will require averaging high 900's!

HHSC's website should have more info on it, but that's the basics. It really measures energy management and pattern planning, good skills for off airport landings.
