Wikipedia:Articles for deletion/Phase lag (rotorcraft)
I added a couple of secondary references describing phase lag and rewrote the article from those references. It is shorter, but hopefully on a more solid basis. In my search for references, phase lag looks to be a notable topic and it is an effect to be accounted for in all modern helicopters. A notable topic, per  and an article with surmountable problems, per , suggests that the article be kept
