Basic Helicopter Controls

Before we discuss the complexities of advanced helicopter controls, let’s start with the basics. Helicopters have four primary flight controls: the cyclic, collective, pedals, and throttle. Each control serves a specific purpose in maneuvering the helicopter through the air.

The Cyclic Control

The cyclic control is usually located between the pilot’s legs and resembles a joystick. The cyclic controls the direction of the helicopter’s movement, pitch, and bank angles. Pushing the cyclic forward causes the helicopter to move forward, pulling it back moves the helicopter backwards, and tilting it left or right banks the helicopter in that direction.

The Collective Control

The collective control is a lever on the left side of the pilot’s seat, which allows the pilot to control the helicopter’s altitude. Moving the collective up increases the lift generated by the rotors, lifting the helicopter upwards, while moving it down has the opposite effect.

Advanced Helicopter Controls

helicopter-control,Advanced Helicopter Controls,thqAdvancedHelicopterControls

Advanced helicopter controls refer to the more specialized controls that are used to operate the helicopter’s many systems and functions. These controls make it easier for pilots to fly longer and more complex missions, even in adverse conditions.

Auto-pilot Controls

Auto-pilot is an advanced control system that automatically controls the helicopter’s movement and stabilizes it in flight. It allows the pilot to focus on other tasks such as navigation, radio communication, weapons systems, or surveillance activities. Auto-pilot technology employs a range of highly advanced sensors and microprocessors that can detect changes in altitude, airspeed, and atmospheric conditions. It can also react to other external factors like turbulence, crosswinds, and other weather phenomena.

Electronic Flight Instrumentation System (EFIS)

EFIS is a computer-based display system that presents a range of critical flight and navigation information to the pilot. These systems use advanced graphical interfaces to display the helicopter’s altitude, speed, heading, and position in relation to the ground. They can also provide information about fuel levels, engine performance, and system alerts that require the pilot’s attention. EFIS systems have become increasingly advanced over the years, and many modern systems now feature touch screens and interactive graphics that make them easier to use.

Components of Helicopter Control System

helicopter-control,Components of Helicopter Control System,thqComponentsofHelicopterControlSystem

A helicopter control system is designed to provide the pilot with the ability to control the aircraft’s altitude, speed, and direction of movement. The system is composed of several key components that work together to make flight possible. Here are the main parts of a helicopter control system:

The Collective

The collective is a control lever located on the left side of the pilot’s seat, which allows the pilot to control the helicopter’s altitude. When the pilot pulls up on the collective, the helicopter will gain altitude, and when the pilot pushes down on the collective, the helicopter will lose altitude. The collective is connected to the main rotor blades through the helicopter’s transmission and is responsible for changing the pitch angle of each rotor blade.

The Cyclic

The cyclic is a control stick located between the pilot’s legs, which allows the pilot to control the helicopter’s direction of movement. When the pilot moves the cyclic forward, the helicopter will move forward, and when the pilot moves the cyclic backward, the helicopter will move backward. Similarly, when the pilot moves the cyclic to the left or right, the helicopter will move in that direction.

The Tail Rotor

The tail rotor is a small rotor located on the tail boom of the helicopter. Its purpose is to counteract the torque produced by the main rotor blades, which would cause the helicopter to spin uncontrollably without the tail rotor. The tail rotor is controlled by pedals located on the floor of the helicopter, which allow the pilot to change the pitch angle of the tail rotor blades.

The Electronic Flight Control System (EFCS)

The EFCS is a computerized system that provides automatic control of the helicopter’s flight. It consists of several sensors and actuators that work together to keep the helicopter stable in flight. For example, if the helicopter starts to pitch up, the EFCS will automatically adjust the pitch angle of the main rotor blades to counteract the motion and maintain stability.

Flight Control Techniques

helicopter-control,Flight Control Techniques,thqFlightControlTechniques

The art of controlling a helicopter is largely dependent on the pilot’s skill and the techniques they use. Here are some common flight control techniques used by helicopter pilots:

Hovering Flight

Hovering flight is when the helicopter maintains a stationary position in the air. To hover, the pilot must adjust the pitch angle of the main rotor blades using the collective while simultaneously adjusting the cyclic to counteract any movement caused by wind or other external factors. Hovering is considered one of the most challenging flight maneuvers for a helicopter pilot.

Vertical Takeoff and Landing (VTOL)

VTOL is a technique used by helicopters to take off and land vertically, without the need for a runway. To perform a VTOL, the pilot must use the collective to increase the pitch angle of the main rotor blades, which will produce enough lift to get the helicopter off the ground. Once in the air, the pilot can use the cyclic to control the direction of takeoff or landing.

Auto Rotation

Auto rotation is a technique used by the pilot to perform an emergency landing in the event of engine failure. To perform an auto rotation, the pilot must disengage the engine and use the kinetic energy stored in the rotor blades to slow the descent and make a controlled landing. Auto rotation is considered an advanced maneuver and requires significant skill and experience to execute properly.

Forward Flight

Forward flight is when the helicopter moves forward in a straight line. To achieve forward flight, the pilot must adjust the pitch angle of the main rotor blades using the cyclic to generate forward thrust. The pilot can then use the collective to control altitude and the tail rotor pedals to control yaw.

Helicopter Flight Controls

helicopter-control,Helicopter Flight Controls,thqHelicopterFlightControls

Helicopter flight controls are a set of devices, mechanics, and operations that work together to achieve the desired helicopter maneuverability. Helicopter controls are made up of three main components: the collective, cyclic, and tail rotor system. All of these work together to control the pitch, roll, and yaw of the helicopter. These controls can be either hydraulic or mechanical, but most modern helicopters use hydraulic systems, which provide excellent precision and responsiveness compared to mechanical controls.

Collective Control

The collective control is a central lever that controls all the helicopter blades’ angles for increase or decreased lift. The increase in lift is achieved by collectively increasing all the blades’ angles equally while decreasing lift will have the opposite effect. Collective control works by changing the angle of the blades collectively to create either lift or reduce lift as desired by the pilot.

Cyclic Control

The cyclic control is situated between the pilot’s legs and controls the pitch and roll movements. The pitch movement is forward and backward, whereas the roll movement is side to side. The cyclic is designed to send commands to the rotor blades, which causes them to tilt and decrease the lift on one side while increasing it on the other. This allows for smooth manoeuvering, and the helicopter can be oriented in any direction, such as forward, sideways, or backward, by adjusting the cyclic controls.

Helicopter Rudder Control

helicopter-control,Helicopter Rudder Control,thqHelicopterRudderControl

The helicopter’s rudder control is located on the tail of the helicopter and controls the yaw movement of the helicopter. It consists of a rudder pedal on each side of the pilot’s seat. Pressing the left pedal will change the helicopter’s yaw to the left while pressing the right pedal produces the opposite effect. When the pilot wants to turn, they push the corresponding pedal to pivot the helicopter in the desired direction. The amount of pressure applied to the pedal controls the amount of yaw angle.

Tail Rotor Control

The functioning of the tail rotor is to counteract the torque produced by the main rotor. The tail rotor’s pedals provide the necessary control over the direction and speed of the tail rotor, which steers the helicopter in the desired direction. The pilot has to be very skilled when using the tail rotor to make the helicopter move as the tail rotor affects the yaw control on the helicopter.

Helicopter Control Systems

helicopter-control,Helicopter Control Systems,thqHelicopterControlSystems

Helicopter control systems are the different types of mechanisms that allow a helicopter to maneuver in different directions and perform complex aerial maneuvers. There are two types of helicopter control systems: mechanical and electrical. Mechanical control systems rely on hydraulic and mechanical linkages, while electrical control systems use electrical signals to control the helicopter’s movements. Both systems work together to ensure the helicopter can be safely and effectively flown.

Mechanical Control Systems

Mechanical helicopter control systems have been around since the early days of aviation. They are made up of a complex series of hydraulic and mechanical linkages which connect the pilot’s controls to the helicopter’s rotor system, tail rotor, and other components such as the landing gear and brakes. These mechanisms allow the pilot to control the helicopter’s attitude and movements, including direction, altitude, and speed.

Electrical Control Systems

Electrical control systems are more modern than mechanical systems and are used in most modern helicopters. These systems use electrical signals to control the helicopter’s movements and are made up of a series of sensors, computers, and actuators. The pilot’s controls are connected to a computer, which interprets the input from the controls and sends electrical signals to the helicopter’s systems, telling them how to move. Electrical control systems are more precise and efficient than mechanical systems but require more maintenance due to their complexity.

Helicopter Flight Control Systems

helicopter-control,Helicopter Flight Control Systems,thqHelicopterFlightControlSystems

The flight control system is designed to control the helicopter’s pitch, roll, and yaw with the use of flight instruments and control devices in the cockpit. It can be either mechanical or electronic, depending on the helicopter’s design and purpose.

Mechanical Flight Control System

In a mechanical flight control system, the pilot uses physical force to manipulate the flight controls, which are connected to the helicopter’s control surfaces by cables or rods. The pilot controls the pitch of the rotor blades with the collective lever and cyclic stick, which is connected to the rotor hub by a swashplate. The anti-torque pedals are used to control the yaw of the helicopter.

Electronic Flight Control System

The electronic flight control system (EFCS) uses computers and automation to control the helicopter’s flight. It includes sensors, actuators, and flight control computers that interpret the pilot’s commands and provide feedback to the control surfaces, helping to stabilize the aircraft and perform complex maneuvers. The EFCS can also provide added safety features such as automatic recovery from unusual attitudes or autopilot functions.

Hybrid Flight Control System

Some helicopters use a combination of mechanical and electronic flight control systems, known as a hybrid flight control system. This allows for a balance between the reliability of mechanical systems and the precision of electronic systems, providing greater safety and performance in challenging flight conditions.

Helicopter Stability and Autopilot Systems

helicopter-control,Helicopter Stability and Autopilot Systems,thqHelicopterStabilityandAutopilotSystems

Stability and autopilot systems are designed to enhance the stability and flight control of the helicopter, particularly in challenging weather conditions or during long flights.

Stability Augmentation Systems

Stability augmentation systems (SAS) use computer-controlled sensors and actuators to provide additional stability to the helicopter’s flight control system. It can help to mitigate turbulence, wind gusts, and other undesirable flight conditions, making flying safer and more comfortable.

Autopilot Systems

The autopilot system automates certain aspects of the helicopter’s flight, such as altitude, airspeed, and heading. It uses sensors and GPS to maintain the helicopter on a predetermined flight path, reducing physical and mental fatigue on the pilot during long flights. It can also incorporate fail-safe features that will take over manual control if there is a malfunction or pilot incapacitation.

Basic Helicopter Controls

helicopter-control,Basic Helicopter Controls,thqHelicopterControls

Helicopter control is vastly different from airplane control, and it takes great skill to manage the three forces upon which helicopter movement relies – lift, thrust, and weight. Each component has a separate control system that the pilot must be familiar with to pilot a helicopter. The pilot can roll, pitch, and yaw the helicopter with its unique set of controls in combination with collective and cyclic pitch, while managing the power output from the engine and propellers.

The Collective Pitch Control

The collective pitch control lever alters the pitch angle of all rotor blades simultaneously, which directly affects the rotor’s lift. The power from the engine is converted into rotational forces that provide lift under the helicopter. When the pilot moves the collective control up or down, the rotor blades’ pitch angle variances change in unison. As a result, the lift force generated changes by the same degree, allowing the helicopter to rise or descend.

The Cyclic Pitch Control

The cyclic pitch control lets the pilot roll, pitch, or yaw the helicopter in the desired direction of motion. It alters the blade’s pitch angle as it rotates around the rotor blade’s span to control the lateral motion and forward motion of the rotorcraft. When the pilot tilts the cyclic control stick in a given direction, he changes the pitch for the rotor blades’ slice-disc part according to the location it is in on the rotorcraft.

Flight Control Systems

Helicopter Control FAQ

Helicopter Control FAQ

If you have concerns or anxiety about helicopter control, we have prepared a list of common questions and answers to help you feel more comfortable.

1. What is the collective control in a helicopter?

The collective control is used to adjust the pitch angle of the helicopter’s main rotors, which determines lift.

2. How does the cyclic control work?

The cyclic control adjusts the pitch of the rotor blades as they rotate, which causes the helicopter to tilt in a particular direction. It allows the helicopter to move forward, backward, left, and right.

3. What is the purpose of the tail rotor?

The tail rotor counteracts the torque created by the main rotor, which would otherwise spin the helicopter in the opposite direction. It also helps the helicopter to turn left and right.

4. Why does the helicopter need anti-torque pedals?

The anti-torque pedals control the pitch of the tail rotor. By applying pressure to the pedals, the pilot can adjust the amount of torque being generated by the tail rotor to maintain stability and prevent the helicopter from spinning out of control.

5. What should you do if the helicopter starts to spin uncontrollably?

If you find yourself in a spin, immediately apply opposite pedal and cyclic control to try and stop the rotation. If this does not work, use the collective control to decrease altitude and reduce speed until the spin stops.

6. How important is weight and balance in helicopter control?

Weight and balance are critical factors in helicopter safety and control. Overloading or improper weight distribution can make the helicopter difficult or impossible to control.

7. What is an auto-rotation?

An auto-rotation is a maneuver where the helicopter’s engine is disengaged, and the rotors spin freely, using gravity to generate lift. This allows the pilot to land safely in the event of an engine failure.

8. How can you prevent a tail rotor failure?

Tail rotor failures are typically the result of improper maintenance or damage to the rotor components. Regular inspections and maintenance can help prevent these kinds of failures.

9. How do you safely land a helicopter?

To land a helicopter safely, the pilot should gradually reduce altitude and speed while maintaining rotor RPM. Just before touching down, they should slightly increase collective pitch to cushion the landing.

10. How do you control speed in a helicopter?

Speed control is primarily achieved through the collective control. To increase speed, the pilot will increase collective pitch to generate more lift and accelerate forward. To slow down, the pilot will decrease collective pitch to decrease lift and decelerate.

11. What should you do if the engine fails during flight?

If the engine fails during flight, the first step is to establish an auto-rotation to land the helicopter safely. The pilot should immediately turn towards a suitable landing site and begin the auto-rotation procedure.

12. How can you tell if a helicopter is experiencing a mechanical problem?

If you notice any unusual vibrations, noises, or behavior from the helicopter, it may be experiencing a mechanical problem. Pilots are trained to listen for these signs and take appropriate action to prevent an accident.
