Not when I went through Wallop. I still remember with some horror the zero speed EOL. It was near enough vertical in the Gazelle.
Having instructed in the military Gazelle, I think you're confusing zero speed with constant attitude, or were doing it wrong. A zero speed auto to the ground / EOL would result in a negative ground speed in anything other than zero headwind and that was definitely not taught.
Don't forget that helicopter ASIs don't register properly at very low IAS and it may appear that the speed is zero when it's not.
