Nothin to do with the green ones mate, this is the story according to the late lamented BV234!
Flying controls operate as any other helo.
Rotor articulation is a bit different.
There is no fore and aft (cyclic) movement in either disk. (there cant be, theyd strike each other) Aircraft pitch is controlled by differential collective between the disks.
Roll is produced by lateral (cyclic) in both disks simultaneously, and yaw by differential lateral cyclic, if you follow my terminology.
Actually there is a slight fore and aft input by a systen called LCT (Longitudinal cyclic trim) that tilts the gearboxes fore and aft to reduce excessive deck angle at speed, but it is not part of the primary flight controls.Conventional flight controls produce these rather unusual inputs via a very complex mechanical mixing unit in the broom cupboard behing the P1.
Due to the dynamics the Chinook develops maximum translational lift in sideways flight to the left, hence the antics of the logging machines plugung sideways on the end of theit long cables - gives them greatly increased lift capacity.
Chinook is extremely docile in handling, yet extremely maneuverable when light. Autorotation is of the thistledown type, rotor inertia is massive and the beggar wont come down fast even if you want it too. Engine off landing is merely a continuous flare to a running landing on the rear wheels which requires quite a lot of runway. I dont know if the military use other techniques.
Take off requires progressive fwd movement on the cyclic as the nose rises to prevent it scuttling off backwards, and vv for landing. There are no torque effects. On icy surfaces it is semi-hover taxiied on the back wheels - groung handling is not helped by rather delicate landing gear, fronts fixed, aft portside castoring and aft stbd only steerable.
What a fabulous toy!
Flying an ILS backwards was fun too (in the sim). Lift off on the landing datum, translate backwards and climb up the slope on instruments. 60Kts sideways and backwards rings a bell??
