Rolling Wings
When the aircraft is rolling, and additional term may be added that will add the wing station distance multiplied by the rate of roll to give additional angle of attack change. Equation 3 will then become
where
- is the rate of roll in rad/sec,
Note that y can be negative. This addition will introduce non-zero even coefficients in the equation which will have to accounted for.

Famous quotes containing the words rolling and/or wings:
“It is only when we are very happy that we can bear to gaze merrily upon the vast and limitless expanse of water, rolling on and on with such persistent, irritating monotony, to the accompaniment of our thoughts, whether grave or gay. When they are gay, the waves echo their gaiety; but when they are sad, then every breaker, as it rolls, seems to bring additional sadness, and to speak to us of hopelessness and of the pettiness of all our joys.”
—Emmuska, Baroness Orczy (1865–1947)
“Girls blush, sometimes, because they are alive,
Half wishing they were dead to save the shame.
The sudden blush devours them, neck and brow;
They have drawn too near the fire of life, like gnats,
And flare up bodily, wings and all. What then?
Who’s sorry for a gnat ... or girl?”
—Elizabeth Barrett Browning (1806–1861)
