how does it change in azimuth?
The front crewman goes right and the back crewman goes left or vice versa, this is DCP (Differential Crewman Position). Pitch is achieved by the crewmen moving forward or aft which is known as Longitudinal Crewman Trim (LCT). Pitch can also be varied by increasing or reducing the power on No1 engine which in turn increases or reduces the speed of the rear rotor thereby increasing or decreasing the lift. Or alternatively by increasing or reducing the power on the No2 engine which gives the same effect on the forward rotor head. If you increase the power on both engines then the lift is increased on both rotor heads and the a/c will lift vertically.

Reason: word change
