[Light Speed]

In a "Flight Journal" article a non Russian pilot discovered that the SU-27 suffers from roll continuance...in some cases the aircraft will continue to over roll near 90 degrees after the stick is centered.
The aircraft has pitch problems and shape control in some manuevers.
With the over roll ..the stick is recentered..but the aircraft still slides laterally.
Comment form Flight Journal on over roll on U.S. aircraft such as F-15 and 16..is the onboard computer acts to counter the dynamic..
The SU-27's comp suite is in catch up mode...to flight shape profile.
Maybe milliseconds slower than U.S. systems..but a serious concern....and leathal at certain elevations.

Absolutely.

The question remains: The jet was established in a stable turn, and after what I figure was about 270 degrees of turn, it rolled over. . .what would cause this?

(For those that don't fly, the stick is centered right after you establish your desired bank angle. This is not like a car where you turn the wheel and hold it there during the turn. In an aircraft, you center the stick once you achieve the desired bank angle as this neutralizes the ailerons and stops the banking maneuver.)

Given the Russians loss of face, I wonder if we will ever find out the "cause" of the mishap?
