F16 Flight Control Surfaces
The F16 is a single-engine, multirole fighter jet that can perform various missions such as air-to-air combat, air-to-ground attack, and reconnaissance. One of the key features that make the F16 agile and maneuverable is its flight control system, which consists of several movable surfaces on the wings and tail of the aircraft. These surfaces are called flight control surfaces, and they allow the pilot to control the pitch, roll, and yaw of the F16.
The main flight control surfaces on the F16 are:
- The elevators:
These are two horizontal surfaces on the tail that move up and down together to change the pitch angle of the nose. The elevators are used to climb, descend, or maintain level flight.
- The ailerons:
These are two small surfaces on the outer edges of the wings that move up and down in opposite directions to change the roll angle of the wings. The ailerons are used to turn left or right, or to correct for crosswinds.
- The rudder:
This is a vertical surface on the tail that moves left and right to change the yaw angle of the nose. The rudder is used to coordinate turns, or to counteract adverse yaw caused by the ailerons.
- The flaps:
These are large surfaces on the trailing edges of the wings that extend downward to increase the lift and drag of the wings. The flaps are used to reduce the speed and increase the angle of descent during landing or takeoff.
- The leading-edge flaps:
These are small surfaces on the leading edges of the wings that extend downward to increase the lift and camber of the wings. The leading-edge flaps are used to improve the high-angle-of-attack performance and stall characteristics of the F16.
- The stabilator:
This is a single-piece horizontal surface on the tail that acts as both an elevator and a stabilizer. The stabilator can move up and down as well as pivot around its center to change both the pitch and roll angles of the F16. The stabilator is used to enhance the maneuverability and stability of the F16 at high speeds and low altitudes.
The F16 flight control system is a fly-by-wire system,
which means that there is no direct mechanical connection between the pilot's controls and the flight control surfaces. Instead, the pilot's inputs are sent to a computer, which then sends electrical signals to hydraulic actuators that move the flight control surfaces. This allows for faster and more precise control, as well as automatic compensation for aerodynamic forces and faults.
The F16 flight control system is also a relaxed static stability system, which means that the F16 is intentionally designed to be slightly unstable in pitch. This gives the F16 a higher lift-to-drag ratio and a lower drag coefficient, which result in better acceleration, climb rate, and turn rate. However, this also makes the F16 more difficult to fly, especially at high angles of attack. To overcome this challenge, the F16 flight control system uses a quadruplex digital flight control computer (FLCC), which constantly monitors and adjusts the flight control surfaces to maintain stability and prevent departure from controlled flight.
The F16 flight control system is one of the most advanced and sophisticated systems in aviation history.
It enables the F16 to perform impressive maneuvers such as tight turns, high-alpha flight, and post-stall gyrations. It also provides the pilot with enhanced safety and survivability in combat situations. The F16 flight control system is a testament to the engineering excellence and innovation of Lockheed Martin and its partners.
Aircraft Flight Control Systems (FCS) -
According to Stratistics MRC, the Global Aircraft Flight Control Systems (FCS) Market is accounted for $12.31 billion in 2020 and is expected to reach $18.93 billion by 2028 growing at a CAGR of 5.5% during the forecast period. Increasing demand of aircraft due to consistent growth of air travel is driving the market growth. However, limited lifespan and high manufacturing costs of components is hampering the growth of the market.

Aircraft flight control systems (FCS) are aerodynamic devices
that combine automation and electromechanical skills. These control systems adjust the orientation of a vehicle about its center of gravity. These aircraft control systems enhance the performance of aircraft and are used to provide safety to the aircraft during pitching, banking and rolling.
Based on the technology, the fly-by-wire segment is going to have lucrative growth during the forecast period as fly-by-wire (FBW) is a technology system which is substituted as an electronically connector for the standard manual aircraft checks. Flight power motions are transformed by cables to digital transmissions and aircraft command machines determine how the actuators can be moved at each controlled area in order to deliver the requested answer, due to these features this segment’s demand is expected to increase in the aircraft flight control systems (FCS) market. By geography, Asia Pacific is going to have high growth during the forecast period to growth in the aircraft industry and airline travel, which in turn is resulting in an increase in the demand for aircraft flight control systems in many of the Asia Pacific countries.

In order to understand the operation of the components and subcomponents of an aircraft, it is important to understand basic aerodynamic concepts
Aerodynamics is the branch of dynamics dealing with the motion of air and other gases which give us the performance we need to fly
It can be associated with the forces acting on an object in motion through the air or with an object that is stationary in a current of air
Several factors affect aircraft performance including the atmosphere, aerodynamics, and aircraft icing
Pilots need an understanding of these factors for a sound basis for prediction of aircraft response to control inputs
