better idea than just showing up and trying it.



No, ASA has flown at the site (Clark Memorial, Williams, AZ ) before
but for our next contest there the organizers have decided that water
ballast will not be allowed. Some members have questioned that rule
on the basis that some pilots used water ballast last time they were
there and thought the risk was acceptable.

I think limiting the discussion to takeoff distance misses the point.
I like to know if I can expect a climb rate that will allow me to
return to the airport, or other known safe landing area, from any
point in the tow.
