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)

When guiding a static rope descent, the speed is controlled by how much braking friction you apply and the load you’re supporting on the rope. The belay device creates resistance as the rope runs through it, and your braking hand determines how much of that resistance translates into slow, controlled movement. Increase the friction or your braking pressure, and the descent slows; ease off and the rope glides faster. Rope length doesn’t set the pace, and you’re not fixed once attached—you can adjust speed at any moment by changing the braking force or the device’s friction. Foot position or stance matters for safety and control, but the actual rate comes from friction through the device and how you manage the load on the rope.
