A system for controlling an aircraft includes an airframe a first airfoil , (40), and a second airfoil (50). At least a portion of the first airfoil (40) and the second airfoil (50) are controllably deflectable so that during a , roll maneuver, the first airfoil (40) generates increased lift and a consequent increased drag, and the second airfoil (50) generates negative lift and a consequent increased drag, the increased lift and the decreased lift generating a roll moment, and the increased drag of the second airfoil producing a yaw moment that counteracts the yaw moment produced by the increased drag of the first airfoil (40) such that no substantial change in aircraft yaw moment …

Why it's free to use
- Filed August 13, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 13, 2022.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
