I've used a similar technique on an Archer. Slow down gradually applying full flap, trim all the way back and the aircraft decends at 200 - 700 fpm as the nose gently bobs up and down. It was described to me as the black hole landing method for night forced landings. I was taught keep my feet off the pedals.
Demonstrating this helped me sell the aircraft to a very safety concious buyer.
DO.
