Reviewing emergency procedures with an appropriately rated Instructor is one of the most critical components of obtaining each CoP. The key here is “Emergency Procedures” not just reserve procedures (eg aircraft emergencies, injuries etc).
It used to be that the only time a person received training in emergencies was the first jump course. With the advent of the SOLO, A, B & C CoP, reviews of this valuable information can be refreshed and new layers of sophistication added to the basics. At the "A" CoP level review the basics (buildings, trees, power lines and low obstacles, free fall emergencies) while refining unintentional night and water jumps, basic RW safety, canopy avoidance drills and group landing approaches. Cutaway practice must be performed and a high level of proficiency displayed.
