What is the maximum allowable deflection for fairleads in cable alignment?

The maximum allowable deflection for fairleads in cable alignment is 3°. This specification ensures that the cables maintain a proper alignment and tension throughout their operation, which is critical for the effective functioning of flight control systems. When the deflection exceeds the prescribed angle, it can lead to increased wear and tear on the cables, potential binding issues, and impaired performance of the flight control surfaces.

Maintaining the deflection within this limit is vital for ensuring safety and reliability in aircraft operations. Fairleads direct the route of the cables and are designed to accommodate certain angles; therefore, the 3° maximum limit serves as a guideline to prevent misalignment and ensure that the flight control systems operate smoothly and predictably.
