How do you teach stretcher entry to the cabin or even double lift entry to the cabin?
Do it on the ground. Sit the stretcher on the ground next to the skid (he should already know how to lift it to the skids) or put both teabags on the ground, and pick them up from skid level. Instructor can stand outside to watch. Simples. Tcchhkkt!
OR: do it on a simple rig in the hangar.
