Over the years, the most common fatal accidents in GA have been student or student and instructor stall on takeoff and/or in the climbing turn to the crosswind leg. I understand the need to practice short field takeoff, but the pitch to Vx attitude immediately after roll to Vx airspeed (PTS), or even after acceleration in ground effect to Vx airspeed (ACS), is missing the more important lesson about level in low ground effect energy. Looking through the accident reports we often see the survivor or witness claim a loss or reduction in power problem. That reduction in energy, not engine power, came from pitching to Vx or Vy attitude early. That reduction in energy, not engine power, was left on the runway remaining before the need to pitch to Vx or Vy attitude. And that Vx or Vy pitch attitude is appropriate only to just clear the obstruction. Beyond the obstruction Vx pitch attitude is certainly not appropriate and Vy pitch attitude is appropriate only in stable air with close monitoring of the airspeed indicator as in ITO. I remember just one dot pitch attitude in ITO and indication of climb. I don't remember any Vy pitch attitude requirement without minimum crossing requirements close to the airport.
Engine power in only one of many sources of energy in flying, especially in the takeoff. Ground effect, wind energy including shear and up and down air, just over the obstruction rather than high over the obstruction, and down drainage egress are also sources of energy that should be taught and utilized.
