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.
