What does the Slat Flap Control Computers (SFCC) primarily do?

The Slat Flap Control Computers (SFCC) are integral to the operation of the aircraft's slat and flap systems. Their primary function is to manage the deployment and retraction of the slats and flaps, which play a crucial role in altering the aerodynamic characteristics of the aircraft during different phases of flight, particularly during takeoff and landing. The SFCC processes information from various aircraft systems and inputs to ensure that slats and flaps deploy and retract correctly according to the flight parameters and pilot commands.

In addition to controlling these functions, the SFCC also ensures that the operation is safe, adhering to certain limits to prevent malfunctions or undesired aerodynamic behavior. This coordination is critical for maintaining optimal lift and drag characteristics when needed to ensure safety and performance during various flight stages. The other options, while potentially related to the broader operational aspects of the aircraft, do not accurately capture the primary role of the SFCC in managing slat and flap functions.
