Interesting presentation. Too bad the person recording did not tend the camera better.
I hope they use swept wing aircraft for teaching the flight portion of the syllabus to swept wing pilots.
The flight characteristics at high AOA and post-departure are significantly different in a swept wing aircraft than in a straight wing aircraft. As they stated, you want to avoid negative training.
If the regulators are going to eventually require this training, it would be good if they also specified which aircraft types are appropriate for this training. No sense creating unnecessary craters.
