"The power required to satisfy the programmed 80 kts and 750 fpm climb rate is less then the initial power used. When engaged at 60 kts reduces the power and sets up a sink rate to reduce climb. This technique may work on departure from runway but not in an area with obstructions. It is better to engage airspeed and heading maintaining the higher power setting and accelerate to VY with cyclic trim. The climb rate will be more than double of the GA mode."
DAPT, I believe you are overdue for refresher training. To put it mildly.
