The Downwind turn
This is more an aerodynamic question that a flight testing one, but maybe somebody in the fraternity could help me. Among light aircraft pilot's there is a belief that a downwind turn from a strong headwing causes the aeroplane to lose airspeed and stall. Many accidents have occured like this. Yet aerodynamically this should not be so, or should it? Is it just a preception or is there another explanation.
