Downwind turn discussion
Elsewhere, thread drift has wandered to a discussion of the characteristics of a downwind turn at a slower airspeed. Passions smoulder on two sides:
One being that the wind has no affect on turn performance nor indicated airspeed, as the aircraft is moving in a parcel of air. The airplane does not know that the air is still or moving, just that it is flying with indicated airspeed, which is not affected by wind. What it was doing into the wind, it will be doing out of the wind once turned 180 degrees. Albeit with a slewed turn, and differing groundspeed.
The other side mentions characteristics of inertia of the aircraft, with the belief that it could be possible for the change from into the wind to out of the wind could occur faster than the inertia of the aircraft [in space, not the parcel of air] could be overcome by the turn acceleration. The possible result being a temporary reduction in indicated airspeed resulting from the turn out of wind, while the inertia of the aircraft is overcome and accelerated in space back to the original IAS, while groundspeed increases too.
Thoughts form the group? How is this concept taught and learned?
