Active flow control systems are being researched, as they might allow to reduce the size, weight, and complexity of high-lift devices.
The loss of the leading-edge high-lift devices resulted in the crew getting a stall warning stick-shake just after lift-off, but the crew kept the aircraft airborne and the slats redeployed less than a minute later.
Data Item 99004 is focused on the pitching coefficient of wings with high-lift devices deployed.
Because of the simplicity of design involving reoptimized high-lift devices and ease of installation, the Increased Gross Weight Program allows operators plenty of decision time to purchase and install Stage 3 kits before January 1, 2000.
