Slider on a ram air parachute

And what is the result of using a round canopy in the high desert. Alan Silver had a good article on whether to use a ram air or round E chute. In the end the round has less potential for problems which could make a bad day even worse.

Sliders are only removed from ramair parachutes for fixed object jumping or dopey stunts. Any 'already in the air' deployments will be likely be at a speed that causes damage either to equipment or jumper. Jumper first, the gear can take more then most people. You really don't want to use a nonslider equipped ramair parachute over 50 mph or so.


Exactly. However, do you want to use a ram air parachute when it deploys slower than an emergency chute?

Google silver parachute ask Allen. He wrote an article regarding ram vs round emergency chutes. Very informative.

I checked with my rigger and jump instructor and here's what he
said:



Your parachute has a slider. The maximum airspeed for slider-off deployments is 65 mph. In an aircraft emergency, you will almost always be deploying at a higher speed than that, so the slider is absolutely necessary. Deploying slider-off at high speed can damage the gear and maybe the jumper.. Your parachute is designed to open as fast as possible without causing damage. It should take about 3 seconds/300 feet for it to open in most situations. Exactly the same as a round parachute of roughly equivalent area.
