, "flyable" means weather conditions such that one can safely launch, fly, and land a hang glider
. This means among other things that the wind
, if any, is blowing more or less directly uphill at launch (if foot launching), is not greater than 25-30 MPH (depending on aircraft
and pilot skill
), and is also blowing at a similar or lesser velocity in the intended landing area (LZ
). It also means that there is sufficient visibility
to avoid impacts with other aircraft and the ground.Soarable
conditions are generally preferred, though first flights are usually scheduled for times of day when it is non-soarable but nicely flyable.
