A flight control system includes a collective position command module for a lift axis (collective pitch) which, in combination with an active collective system, provides a force feedback such that a pilot may seamlessly command vertical speed, flight path angle or directly change collective blade pitch. The collective position command module utilizes displacement of the collective controller to command direct collective blade pitch change, while a constant force application to the collective controller within a “level flight” detent commands vertical velocity or flight path angle. The “level flight” detent provides a tactile cue for collective position to reference the aircraft level flight attitude without the pilot having to refer to the instruments and without excessive collective controller movement.

A cord material suitable for use in lined textile structures with a gliding component includes a plurality of uniform strands, and a deviant strand. The deviant strand is different from the uniform strands in some characteristic affecting aerodynamic or hydrodynamic properties of the cord, such as size or surface properties. Each uniform strand can have a substantially equal cross section area, while the deviant strand has a cross section area at least five times greater than one of the uniform strands. The strands can be braided or woven together. A major benefit of the material can be that vibration induced drag is significantly reduced or eliminated in lines made with the material. Another advantage is that lines made from the material can have more consistent, predictable line drag, which can improve the quality of handling.
