This chart is based on a
SkyDoc™ Aerostat that has been trimmed at +4 degrees of attack angle, and
no payload. Changes in the attack angle and payload will vary the height the
SkyDoc™ Aerostat will settle at in wind conditions and vary the amount of
lift. Varying the attack angle from +4 to -8 degrees, changes in wind speed,
and amount of payload can vary the angle of the tethered SkyDoc™ from 90
Degrees to 20 Degrees and the amount of lift available. Greatest stability with
lift is generally found by trimming the Aerostat to a -4 degrees attack angle.
