I’m not sure whether that’s inherited from BK-117, or whether any other Eurocopter models do the same. Is that innovative or scary?
I am not familiar with the Eurocopter heli's either, but with hydraulic servos used in flight controls, the input from the cyclic and collective needs to be as 'friction free' as possible to prevent jerky control movement. A Teleflex type cable has virtually all its surface area in contact with the outer cable, giving it maximum opportunity to bind if lubrication is lost or if contaminated with grit etc. and we all know how well helicopters can stir up dust.
I would have to guess that the push/pull cables in the 145 have a better or new type design than the standard cables currently in use on other A/C. Perhaps they have a throwaway life.
