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. We experimented with varying descents from an emergency descent profile—from coming down at nearly 10,000 fpm to seeing if we could cure being high and fast on an arrival procedure.

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. The resulting loss of lift leads to a rapid descent by the aircraft.

The reaction in the form of increased thrust allows the aircraft to overcome drag and accelerate or climb. The complication with helicopters is that the main rotor is driven by an engine that applies a twisting force (torque) to spin it. Other Designs The tail rotor is not the only way to solve the torque reaction problem.

The crew acknowledged and said that they were at the ideal point of descent and waiting for clearance. This signifies a significant increase in drag which is causing the airspeed to drop by 15 to 20 knots. The approach controller instructed the crew to continue to wait for the descent clearance. The flight crew confirmed SANPA.

Another advantage of the counter-rotating props is the elimination of torque roll. This is the tendency to dig in the left tip float during takeoff while countering engine torque. The airfoil is a Harry Riblett shape, giving modernized flow separation on the leading edge for a soft stall yet with good lift and drag performance.
