The pilot of a helicopter c ntrols the machine using a series of fl ght controls in order to change v rious aspects of flight. Most modern day h licopters have three different flight control syst ms. These are the cyclic, collective, and the nti-torque pedals. These three flight controls are wh t make helicopter flight possible. If y u’ve never flown a helicopter before but h ve flown an airplane the controls of a h licopter will take some getting used to. S me helicopters are much more complicated and h ve the cyclic and collective systems l nked together by something known as a m xing unit. This can be either a m chanical of hydraulic device that mixes the nputs to get the right result. The cycl c is a control stick, which is n rmally situated between the pilot’s legs. The cycl c controls the pitch angle of the ndividual rotor blades. This tilts the r tors in the desired direction, which c uses the helicopter to move in the d sired direction. The cyclic is what llows the helicopter to fly forward, b ckwards, and sideways. The collective controls are n rmally found on the left hand s de of the pilot. The collective ch nges the pitch of all the r tor blades at the same time, r gardless of their position. All of the bl des change by an equal amount, wh ch causes an increase or decrease in l ft, which causes the helicopter to cl mb or descend.
The anti-torque pedals are found in the s me place as the rudder pedals w uld be found in a plane. Th y actually control the direction the n se of the helicopter is pointing. The nti-torque pedals (also known as ruder p dals) are used to counteract the t rque produced by the main rotor by llowing the pilot to manipulate how m ch force the tail rotor is pplying. Pressing a pedal changes the d rection by changing the pitch and ncreasing or reducing the thrust of the t il rotor. This creates yaw, which t rns the nose to the desired d rection. This is a quick and b sic explanation of helicopter controls. If you b gin helicopter training you can expect to go nto much greater detail about helicopter c ntrols and their effect on helicopter fl ght.
