I thought I knew how to PLF until yesterday when I needed it. Downsized to a smaller canopy (still relatively large)... tried to avoid traffic & ended up on runway. No big deal I thought. I've landed on the runway as a student without a problem. Then I got a pop up towards the end of my flare and my PLF turned into a somersault thing with my body pivoting off of my forearm.
Surprisingly I walked away without a problem but I realized it could have been much worse.
How often do experienced jumpers practice PLFs?
Do you practice them on landings even if not needed once in a while?
