In our club in hot Aussie conditions, the CFI and his mob will discus
matters with you, if you take off without adequate water, a hat and a relief
system. The drop off in pilot performance due to dehydration is dramatic and
has been attributed to many accident. We have professional colour charts in
the toilets warning of the risks. The volume of water carried for drinking
on a long flight in hot conditions is amazing. Food is another seperate
issue that hopefully someone might like to start a new thread.

The "****a phone" to the outside is great and perhaps a internal comtainer
syastem. You must ensure secure fitting as corrosion is an issue. So is the
little yellow crysals during negative G manouvers. Yes it has happened to
me.

Wine cask bladders with a suitable valve are Ok for ergonomically suitable
gliders and people. The cut off disposable petrol filters work great with
suitable sanding to a smooth surface.

Catheters (called in our club Irish Condoms due to the hole in the end )
work well.

All of these though are best tried on the ground or at home, so troubles are
sorted ot beforehand.

Good soaring
