In the world of aviation, there are numerous terms and components that play a crucial role in the functioning of an aircraft. One such component is the Slat Flap Control Computer (SFCC). The SFCC, also known as the Slat Flap Electronic Control Unit (SFECU), is an essential part of an aircraft’s wing system. It is responsible for the control and management of the slats and flaps, which aid in the overall performance and safety of the aircraft during takeoff and landing.
But what exactly is the Slat Flap Control Computer, and how does it work? Let’s delve deeper into this vital aviation component.

Understanding the Slat Flap Control Computer (SFCC)
The Slat Flap Control Computer, abbreviated as SFCC, is an electronic unit that plays a vital role in controlling the movements and positions of the slats and flaps on an aircraft’s wings. The SFCC receives inputs from various sensors and pilots’ commands, processes the data, and sends commands to the actuators that control the slats and flaps.
One of the primary functions of the SFCC is to calculate and maintain the optimal position of the slats and flaps based on various factors, such as the current airspeed, angle of attack, and aircraft weight. These calculations are essential to ensure optimal aircraft performance, especially during critical phases of flight such as takeoff and landing.
Furthermore, the SFCC also incorporates safety features to prevent any potential hazards or malfunctions related to the slats and flaps. It continuously monitors the position and movement of these components, and in the event of any discrepancy or failure, it can activate warning systems and initiate corrective actions to ensure the aircraft’s safety.
The Functioning of the Slat Flap Control Computer
The Slat Flap Control Computer utilizes a combination of hardware and software to control and manage the slats and flaps on an aircraft’s wings. Let’s take a closer look at the various components and processes involved.
Components of the Slat Flap Control Computer
The SFCC consists of several components that work together to ensure the optimal performance of the slats and flaps. These components include:
1. Electronic Control Unit (ECU): The ECU is the main component of the SFCC. It receives inputs from various sensors and computes the necessary control commands for the slats and flaps.
2. Sensors: The SFCC receives inputs from various sensors installed throughout the aircraft. These sensors provide data on airspeed, angle of attack, weight, and other critical parameters needed to calculate the optimal position of the slats and flaps.
3. Actuators: Once the SFCC processes the data and determines the optimal position of the slats and flaps, it sends commands to the actuators. These actuators are responsible for physically moving the slats and flaps to the desired positions.
Processes Involved
The functioning of the SFCC involves several processes that ensure the optimal control and management of the slats and flaps. These processes include:
1. Data Processing: The SFCC receives inputs from various sensors and pilots’ commands. It processes this data to calculate the optimal position of the slats and flaps based on factors like airspeed, angle of attack, and aircraft weight.
2. Command Generation: Once the data is processed, the SFCC generates the necessary commands for the actuators. These commands specify the desired position of the slats and flaps based on the calculations performed.
3. Command Transmission: The SFCC sends the generated commands to the actuators, which physically move the slats and flaps to the desired positions. This ensures that the aircraft’s wings are appropriately configured for optimal performance during different phases of flight.
The Importance of Slat Flap Control Computer in Aviation
The Slat Flap Control Computer plays a critical role in aviation, contributing to both the performance and safety of an aircraft. Its importance can be summarized as follows:
1. Enhanced Performance: The SFCC’s ability to calculate and maintain the optimal position of the slats and flaps ensures optimal aerodynamic performance during critical phases of flight. This results in improved lift, reduced drag, and enhanced maneuverability, ultimately leading to a safer and more efficient flight.
2. Improved Safety: By continuously monitoring the position and movement of the slats and flaps, the SFCC can detect any potential malfunctions or failures. In such cases, it can activate warning systems and initiate corrective actions to prevent accidents or dangerous situations during takeoff, landing, or other critical flight operations.
3. Automation: The SFCC’s automation capabilities reduce pilot workload and ensure accurate and timely control of the slats and flaps. This allows pilots to focus on other critical tasks during flight, improving overall operational efficiency and safety.
Overall, the Slat Flap Control Computer (SFCC) is an indispensable component in aviation. Its ability to control and manage the slats and flaps effectively contributes to the overall performance, efficiency, and safety of an aircraft.
