Definition
A method of linking the ailerons and rudder of an airplane through springs so that movement of the aileron control automatically applies a proportional amount of rudder in the same direction. The springs allow the pilot to override the connection by applying independent rudder pressure when needed, such as during a slip or crosswind landing.
Plain English
The ailerons and rudder are linked by springs so that when you turn the control wheel, the rudder moves with it automatically. You can still push the rudder pedals on your own when you need to, because the springs give way.
Context Anchor
Seen in descriptions of aircraft flight control systems, especially where one control is designed to help coordinate or influence another control.
Derivation
Coupled means joined together. Interconnect means a connection between two systems. The springs are what make the connection flexible rather than rigid, so the two controls move together but can still be separated when needed.
Why Pilots Care
Reduces adverse yaw and improves coordination during turns, lowering pilot workload.
Analogy
It is like two handles connected by a spring. Pulling one handle tugs on the other, but the other handle can still be held in place or moved separately.
Grounding Statement
The spring link gives a control a nudge, not an unbreakable command.
Intuition Check
Do not read coupled as meaning the controls are locked together. Here, coupled means spring-linked: one control influences the other, but does not rigidly control it.
Example Sentence 1
Because the ailerons are coupled with interconnect springs, a slight bank input also produces a small rudder deflection, helping keep the turn coordinated.
Example Sentence 2
During preflight, the mechanic checked that the interconnect springs still provided proper tension between the aileron and rudder systems.
