When skydiving from a helicopter at 3,000 feet. How long should you wait before depoloying your chute?

Since a parachute needs wind to open. How long will it take to build up enough wind speed to properly open the chute? And, at what altitude would you reach that speed?

you generally want to pop your main at about 2,000 feet… then have about 800 for it to open and assess the situation. That gives you time to decide what to do. I’m speaking from experience. I popped mine at 2,000 … the slider fouled… and I had to cut away to my reserve. I cut away at about 1,200 feet, and my reserve opened at about 800-900 feet so I had enough time to get my head together.
From when you jump to when you pop, from 3,000 you’ll have about 7 to ten seconds of flight.

DEFINITELY wait until you’ve cleared the helicopter’s blades.

Don’t skydive from helicopters.

right away, otherwise you will be in the ground in about 5 seconds

You could pitch the main right off the skid but that opening would suck. From three thousand feet you’ve got a good five to ten seconds before you reach 2000 feet. For a skydiver with a C or D license we have to have started the main deployment prior to 2000 feet above the ground. I would take a minimum of a five second delay. Like I said, you could pitch right off the skid, but that wouldn’t be very fun.
on a normal jump from a plane at that altitude I will pitch right out the door and open in the prop blast. For a full altitude jump you will reach terminal velocity in about 20 seconds. You can adjust the speed based on body position and a few other things.
