to rappelling is taught on a static tower (see figure 1-1). Using the building block approach to training, Soldiers systematically progress to more demanding platforms including taller static towers and helicopters. The static tower used may vary in size and height, but a 34foot minimum is required. The concept of learning basic rappelling techniques before helicopter operations does not vary. Figure 1-1. Static rappel tower Note. Static rappel towers should be inspected annually by post safety or post engineers. Anchor points should be load tested every six months. Installations, major Army commands, and unit commanders may establish additional policies and safety procedures, as needed, to ensure safe and effective rappelling operations.
