In guiding a static rope descent, what is the key factor to control speed?

• A. Rope length alone determines descent speed.
• B. Operator footwork controls descent rate regardless of equipment.
• C. Friction via belay devices and controlling load to modulate descent rate.
• D. Descent speed is fixed once the rope is attached.

Answer: (C)

Descent speed in a controlled static rope setup is determined by how much braking friction you generate and how you manage the load on the rope. The belay device creates resistance, and your braking hand and body position control how much of that resistance is felt. When you apply more braking force or put more load on the rope, the system resists gravity more, slowing the descent. Releasing braking or reducing load allows gravity to pull you faster. Rope length only sets distance, not rate. Footwork affects balance and control, but the actual speed comes from the friction you create with the device and how you modulate the load. And the speed isn’t fixed once the rope is attached—you can adjust it anytime by changing the braking and load.
