Cyclic
~ controls helicopter position over the ground in both a >longitudinal and >lateral direction
~ is neither a position control or a simple rate control
~ is an acceleration control
~ you move cyclic to the right if you want to accelerate to the right
~ you judge the acceleration to the right
~ when helicopter has accelerated to the correct speed to the right, you center the cyclic
~ as helicopter approaches the desired position, you move the cyclic to the left
~ you judge the decelleration
~ if helicopter is decelerating too rapidly, reduce the amount of left cyclic
~ if helicopter is not decelerating rapidly enough, increase the amount of cyclic
~ as helicopter comes to a stop, center the cyclic

~ in a hover pilot has to learn what pitch attitude will give him zero airspeed flight, and then simply maintains that attitude
~ if helicopter drifts forward or backward, slight attitude changes are made to gain and lose forward or rearward speed until the desired position over the ground is achieved

~ besides pitch attitude, pilot needs to also control the helicopter laterally with the cyclic control
~ he does this by banking the aircraft
~ in forward flight, banking the aircraft causes the helicopter to turn
~ in hovering flight, banking the aircraft simply translates the helicopter laterally
~ by maintaining a no-bank attitude, the pilot will maintain a zero drift rate
