1. An apparatus, comprising: a collective control column for an aircraft, the collective control column includes: a rotational interface rotatable in a first direction to provide a first input and a second direction opposite the first direction to provide a second input, the collective control column including tapered surfaces engageable by the rotational interface and structured to encourage the rotational interface to be in a first position between a second position associated with the first input and a third position associated with the second input;a memory to store instructions; anda processor responsive to the first input to execute the instructions to cause the aircraft to perform operations associated with flying the aircraft, the processor responsive to the second input to execute the instructions to cause the aircraft to perform operations associated with idling the aircraft. 2. The apparatus of claim 1, wherein the rotational interface includes a collar that at least partially surrounds the collective control column. 3. The apparatus of claim 2, wherein the collar includes surface structures on an exterior surface of the collar to indicate a rotational position of the collar relative to a longitudinal axis of the collective control column. 4. The apparatus of claim 2, wherein the collar includes a follower structured to be biased into engagement with a surface of the collective control column. 5. The apparatus of claim 4, wherein the collar is structured to be longitudinally and rotationally biased to a central position between a first position of the collar associated with the first input and a second position of the collar associated with the second input. 6. The apparatus of claim 5, wherein the collective control column includes a detent, in the central position, the follower is to be received in the detent to substantially secure the collar against inadvertent rotation. 7. The apparatus of claim 6, wherein the collar is movable relative to a longitudinal axis of the collective control column to remove the follower from the detent and to enable the collar to be rotatable in either of the first direction or the second direction after the follower is removed from the detent. 8. The apparatus of claim 1, wherein the collective control column includes a grip and a head, the rotational interface being disposed between the grip and the head. 9. The apparatus of claim 1, further including a switch responsive to the rotating of the rotational interface in the first direction or the rotating of the rotational interface in the second direction, the switch being coupled to the processor to enable the processor to receive the first input or the second input. 10. An apparatus, comprising: a collective control column, including: a tapered surface; anda rotatable ring to engage the tapered surface, the rotatable ring to enable switchable electronic control of an engine performance state between a first state associated with flight engine control and a second state associated with idle engine control, the ring being coaxially mounted to the collective control column, the tapered surface structured to encourage the rotatable ring to be in a first position between a second position associated with the first state and a third position associated with the second state. 11. The apparatus of claim 10, wherein the rotational ring is releasable to enable rotation of the ring by moving the ring relative to a longitudinal axis of the control column to enable a protrusion to be removed from a detent. 12. The apparatus of claim 10, further including a spring to longitudinally and rotationally bias the ring to the first position between the second position associated with the first state and the third position associated with the second position. 13. The apparatus of claim 12, wherein the collective control column includes a detent, the ring includes a follower to be urged into engagement with the tapered surface or the detent of the collective control column, an interaction between the spring and the ring and between the follower and the tapered surface to bias the follower to be disposed in the detent. 14. The apparatus of claim 10, wherein the rotational ring is disposed adjacent a base or a head of the collective control column. 15. An apparatus, comprising: a rotorcraft including main rotor blades and tail rotor blades;a collective control column disposed in the rotorcraft, the collective control column, including: tapered surfaces;a rotational interface to engage the tapered surface, the rotational interface rotatable in a first direction to provide a first input and a second direction opposite the first direction to provide a second input, the tapered surfaces to encourage the rotational interface to be in a first position between a second position associated with the first input and a third position associated with the second input;a memory to store instructions; anda processor responsive to the first input to execute the instructions to cause the rotorcraft to perform operations associated with flying the rotorcraft, the processor responsive to the second input, the processor to execute the instructions to cause the rotorcraft to perform operations associated with idling the rotorcraft. 16. The apparatus of claim 15, wherein the rotational interface includes a collar that least partially surrounds the collective control column, the collar being rotationally and longitudinally biased by a spring relative to a longitudinal axis of the collective control column. 17. The apparatus of claim 16, wherein the collar is movable from a secured position that substantially prevents rotation of the collar to a released position that enables the collar to be rotated in the first direction and rotated in the second direction. 18. The apparatus of claim 17, wherein, in the secured position, a protrusion of the collar is received in a detent of the collective control column, the collar being movable relative to the longitudinal axis to remove the protrusion from the detent and to enable a transition of the collar from the secured position to the released position. 19. The apparatus of claim 16, wherein the collar includes a follower to be urged into engagement with a tapered surface or a detent of the collective control column, an interaction between the spring and the collar and between the follower and the tapered surface to encourage the follower to be disposed in the detent. 20. The apparatus of claim 15, further including a switch responsive to the rotating of the rotational interface in the first direction or the rotating of the rotational rotational interface in the second direction, the switch being coupled to the processor to enable the processor receive to the first input or the second input. 21. An apparatus, comprising: a collective control column for an aircraft, the collective control column, including: a rotational interface rotatable in a first direction to provide a first input and a second direction opposite the first direction to provide a second input, the collective control column including means for encouraging the rotational interface to be disposed in a first position between second and third positions associated with the first input and the second input. 22. The apparatus of claim 21, wherein the collective control column includes a grip having an outer surface, the rotational interface being outwardly offset relative to the outer surface. 23. The apparatus of claim 22, wherein the rotational interface includes a chamfer that extends outwardly relative to the outer surface. 24.
