How to control a Chinook...

I believe I am correct when I say that there is definately no "notar" type system on a chinook or a tail rotor. Essentially when pedals are pressed in the cockpit both rotor systems are tilted in opposite directions.

I got this from another website:
"This is accomplished by pedal only inputs. By depressing one pedal over the other, cyclic inputs are put in both systems in opposite directions to pivot about the center of the aircraft. Both rotor systems receive equal cyclic inputs, and the helicopter just spins nicely at its center without the pilot having to move his cyclic control at all. A pivot around the tail is accomplished by heavy cyclic inputs by the pilot, and little or no pedal inputs. This will make the tail stay in one place, and the nose of the aircraft move laterally until it spins about the aft mast."

Needless to say it is a complicated system that requires a lot of linkages, a lot of control tubes, and a pilot who trusts his maintenance crew to make sure it all was put together properly!

Hope you won that pint....
