Descent Tail Torque

The deicing boots seem to mate so smoothly with the wings and tail that the only way to tell where that happens is that they are different colors. Pulling the prop back to 1,500 rpm (from its normal 1,700 rpm) reduces the noise level but does not change speed or fuel burn as the autothrottle adjusts torque. gph fuel burn.

The rotational force thats needed to move an object about an axis is called torque. The simplest formula for torque is: Torque = F x L L is the distance between the object and the axis of rotation, also called the moment arm. Most of the ailerons mass lies behind the hinge, making it tail-heavy.

The complication with helicopters is that the main rotor is driven by an engine that applies a twisting force (torque) to spin it. This is called torque reaction, and if its left unchecked, the helicopter fuselage will spin in the opposite direction of the main rotor. These rotors create equal and opposite torques that cancel out.

At approximately 30-40 feet agl, the spinning stopped and the helicopter appeared to stabilize for a brief moment before continuing a nose-low, forward descent into the grass north of Runway 28. The operator confirmed that the tail rotor had been installed the day before the accident. As it descended it spun around 2-3 times.

As the airplane contacts the ground, the tail will be forced down very rapidly by the back-elevator pressure and by inertia acting downward on the tail. This not only stops the descent, but actually starts the airplane climbing. This climbing during the roundout is known as ballooning.

The elevator, situated on the horizontal tail surface, adjusts pitch, raising or lowering the nose for ascent or descent. The rudder, attached to the vertical tail fin, manages yaw, enabling the nose to move left or right. Helicopters use a cyclic, collective, and anti-torque pedals, requiring coordination for stability.

Flying in clouds of cold and warm fronts can lead to very small supercooled water droplets which build up as rime ice on the parts of the aircraft exposed to the wind: probes, antennas, and the leading edges of the wings and tail. The crew acknowledged and said that they were at the ideal point of descent and waiting for clearance.
