Great little write up on how to perform the forward slip! Although I do question wether it works in this sim or not? I have attempted it many times with very little if any at all success. Maybe it is something we can only do on newer planes?
We would use this while flying the C130s a lot, as you could balloon very quickly once you push flaps to 100.
