For a single main rotor helicopter, control around the vertical axis is handled by the anti-torque rotor (tail rotor) or from the fan’s airflow on a NOTAR type helicopter. Like in an airplane, rotation around this axis is known as yaw.
Does a helicopter have rudder pedals?
The anti-torque pedals are located in the same place as the rudder pedals in an airplane , and serve a similar purpose—they control the direction that the nose of the aircraft points.
Do helicopters have pedals?
There are three major controls in a helicopter that the pilot must use during flight. They are the collective pitch control, the cyclic pitch control, and the antitorque pedals or tail rotor control.
How a helicopter is controlled?
A helicopter has four controls: collective pitch control, throttle control, antitorque control, and cyclic pitch control . ... The throttle control is twisted outboard to increase rotor rpm and inboard to decrease rpm. The antitorque controls are pedals linked to operate a pitch change mechanism in the tail rotor gearbox.
How does a helicopter control its movement in air?
In addition to moving up and down, helicopters can fly forward, backward and sideways. This kind of directional flight is achieved by tilting the swash plate assembly with the cyclic , which alters the pitch of each blade as it rotates. As a result, every blade produces maximum lift at a particular point.
Why is helicopter pilot on right side?
Because the cyclic controls attitude and direction, it is the primary control of the helicopter, and right-handed pilots prefer to keep their right hand on it because it makes it more comfortable to control .
What happens when a helicopter engine fails?
If the helicopter engine stops, everything will go quiet in the cockpit, and the machine will yaw violently to one side . When this happens, the pilot needs to instantly lower the collective, taking the pitch off the rotor blades, and initiating a descent.
What do pedals do in helicopter?
Hovering turns are commonly referred to as “pedal turns.” At speeds above translational lift, the pedals are used to compensate for torque to put the helicopter in longitudinal trim , so that coordinated flight can be maintained. The cyclic control is used to change heading by making a turn to the desired direction.
Do helicopters have steering wheels?
To achieve this, the project replaced the helicopter’s cyclic stick, which is responsible for movements around the longitudinal and transverse axis, with a steering wheel . Pilots simply need to turn the wheel in the intended direction.
How high can a helicopter fly?
| Helicopter Name First Flight Highest Altitude Records | Mil Mi-8 1961 30,000 feet | Boeing CH-47 Chinook 1961 >18000 feet | AgustaWestland AW109 1971 13,800 feet | Sikorsky H-60 Black Hawk 1974 19,151 feet |

Why do helicopters take off backwards?
Helicopters take off backward to allow the pilot to keep the helipad in sight in case they need to re-land in an emergency . When taking off vertically, the helipad disappears out of sight around 30ft to 50ft up, backing up allows the pilot to keep the helipad in sight through the chin bubble window.
Can helicopters fly upside down?
Flying a helicopter upside down is rather different from flipping over an aerobatic airplane, whose wings can generate lift whichever way they’re pointed. Helicopters can only can only send lift-generating air in one direction . Turn it over, and it’s going to accelerate you toward the ground.
Why do helicopters need a second set of blades on the tail?
The second job of the tail rotor is to control the direction the nose of the helicopter points , and thus the direction the pilot and passengers face.
What was the life expectancy of a helicopter door gunner in Vietnam?
According to popular legend, the door gunner on a Vietnam era Huey gunship had a life-span of 5 minutes . This was obviously exaggerated but displays the hazards of this particular military job at the time. Today, helicopters like the UH-60 have two machine guns firing out of two windows located behind the pilots.
Do any helicopters have ejection seats?
2- Are there any helicopters with ejection seats? Yes . ... The seat is more of a tractor rocket system than a full ejection seat, but it does provide for escape from the helicopter. The system first fires explosive bolts to jettison the rotor blades then jettisons the canopies and finally tractors the crewmen out.
Do helicopters have 2 pilots?
The pilot will sit in the cockpit with a co-pilot; helicopters not requiring 2 pilots can have another person in the front seat . There are four main controls a helicopter pilot must use in flight: cyclic, collective, anti-torque pedals, and throttle.
