Yay, Bill - You nailed it.
When I provide J-3 Cub tailwheel transition training, I have the student do the following:
Set low cruise in C-85, Normal cruise in A-65
Head out of the cockpit. No watching the airspeed gauge. Look at the clouds or sky.
Try to find the point where the A/C is on the verge of stalling. Hold this as best they can. Milk it even more.
Notice the feel of the controls, get used to what the A/C feels like in the area of incipient stall. If it takes a large amount of stick and rudder just to keep the bird on an even keel, you are there.
Finally, stall the A/C on your command. This is done from an easy entry and a hard entry.
I can agree with all parties, going out to the practice area; and stalling the A/C has limited benefits. All instructors are keenly aware that the teaching objective is really stall awareness and avoidance. What to do when the stall occurs is a required skill. But, I try to get a student to develop a feel for the A/C and be aware when the A/C says it is not happy.
I did not read the original article, but if the point is to suggest that going out to the practice area to STALL & RECOVER is wasted training time --- I see the point. As an instructor I would rather a person become proficient at stall awareness and avoidance. In some airplanes the recovery is not pretty and sometimes not possible from pattern altitude.
