The active posters here who matter also show at least a modicum of

since both civility and competence have a common root in intelligence.


Your own words just two days ago dip****.


Civility, not respect. I deliberately wrote it that way.

Default Gliders in the Grand Canyon

As a cross-country soaring enthusiast, the notion of soaring below the
rim and out again (assuming the legalities of course) is exciting --
and foolish.

A fundamental rule of safe soaring is that you always have a safe
place to land, iow never assume there is a thermal between you and the
closest place on the ground that will not break your glider. I've seen
the Big Ditch a number of times from the air (and twice from my
sailplane) and have never seen a safe place to land.

Understood.

If you _did_ have a safe place to land, somewhere, would there be enough
rising air in the canyon to safely lift you out after gliding some distance
below the rim? If so, how low could you go? I don't know much about sources
of rising air for gliding, so the question may be nave.

Yep, mostly you.

Though in fairness you're mostly malicious.

The answer to your first question is Yes. I have thermalled over the
canyon once, I have friends who have thermalled over the canyon a
number of times, and those thermals had to have originated on the
canyon floor, where daytime heating would be good.

Next time you're there in warm weather and you see cumulus clouds
forming over the canyon, visualize lines from their bottoms down to
the ground, adjusted for winds. You'll see that many of the CUs
originated from thermals by the river bank.

Good thermals, too. Making it to the Canyon is a real treat for
Arizona x/c pilots. I hope to do it again in a few weeks en route to
Parowan, UT.

Don't the current rules pretty much exclude glider flights over the canyon,
even above the rim? It doesn't look like you can get below 11,500 MSL or so,
and not at all through the no-fly areas. Unless gliders are special (which
they could be, since I think the main motivation for the SFRA is noise).

No. The special air traffic rules specify 14500 MSL as the lowest you
can go. That gives a VFR window up to 17999, or higher with clearance
from Center.
