The helicopter turned left to return to the airport, travelling at about 85 knots. The indicated airspeed had fallen below 65 knots and was still decreasing. The helicopter was at treetop height with an indicated airspeed of zero knots when the right yaw ceased. He asked a mechanic to come and verify the mast nut torque.

The flight crew adjusted the icing bug to 165 knots. The temperature at their cruising altitude was around -9° with westerly winds at 46 knots. The ATR’s airspeed was 191 knots. The crew acknowledged and said that they were at the ideal point of descent and waiting for clearance. The flight crew confirmed SANPA.

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.

“We routinely taxi at 1200 rpm due to the low spray…[we] can cruise at 10 knots” in displacement mode, something a Goose can’t do. 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.
