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 Cabri G2 comprises a shrouded tail rotor, usually referred to as a “Fenestron” (a registered trade mark of Eurocopter) that was proven to provide excellent maneuverability in every flight condition, in every direction of flight up to 40 kt at least. The pair took off from Gruyère Aérodrome at 14:00.

The flight crew adjusted the icing bug to 165 knots. 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 ATR’s airspeed was 191 knots.

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.

True, a slightly higher aspect ratio wing was desired, which in turn required a larger vertical tail and thus a little extra mass, but the size, approximately 20% larger than a Widgeon, was set. 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.
