Static Lateral and directional stability due to combined Dihedral effect and sweep  




My question here is if for a positive side slip (nose of aircraft to the left)  the aircraft is yawing to right and rolling to the left due to swept back wing. Then what will be the effect of dihedral  on the already left rolling aircraft as the wind is coming from the right and right wing is already higher than the left. Will the Dihedral here will be stabilizing or destabilizing. From the explanation given in the video ,  To visualize the question pause the video at @11:05 rotate the aircraft to the left  around the longitudinal axis and keep the wind direction as same.   Thanks once again 🙂
