rolling takeoff

Correlation of the DFDR and CVR recordings disclosed that the flightcrew had set the flaps and stabilizer trim at 10° and about 5° aircraft noseup, respectively, for takeoff. A rolling takeoff was made, takeoff thrust was stabilized at 80 KIAS, and left rudder and right aileron were used to compensate for the right crosswind. The V₁ and V_R callouts were made about 2 sec after these speeds were recorded by the DFDR.
