B737-800 with Flap 40: what causes increased roll sensitivity?
On approach with the -800 today the winds on approach were gustier than would have been anticipated from the tower wind given. In these conditions the -800 is noticeably more sensitive in roll and seems to be a lot easier to over-control. I noticed that the -700 does not exhibit this trait to the same degree. The aircraft sets up an oscillating roll similar to Dutch Roll if the pilot is overcompensating for the twitchiness. Does anyone know the explanation for this aircraft characteristic (either design-related or aerodynamic?)
Thanks!
