Does extending the flaps aggravate the roll off tendency at stall?

Extending the flaps on an aircraft alters the aerodynamic characteristics, particularly at slower speeds. When flaps are deployed, they increase lift and drag, which can lead to a change in the aircraft's center of pressure. At or near stall speeds, this change can exacerbate any rolling tendencies, especially if there are asymmetrical lift conditions due to factors like variation in weight distribution or control input.

This is particularly relevant during slow flight conditions, where the aircraft is already close to its stall threshold. The increased lift from the flaps may not be enough to counteract the loss of control effectiveness and the potential for a roll-off is heightened as you approach the stall angle of attack. Therefore, saying that extending the flaps aggravates the roll-off tendency at stall is accurate, as the deployment does alter the handling characteristics, making the situation more precarious when nearing stall conditions.
