Re: [hankusaurelius] Opening in High Winds Aloft

I have no idea what this person's context was when he/she made the comment, but the actual opening of the canopy won't be affected by high winds aloft.
Orientation to the wind line, however, does become very important. In very high winds aloft, I like to face into the direction of the winds at opening altitude. Assuming an upwind jump run, this keeps me facing directly into the upstairs winds while I handle all of my post-opening tasks prior to clearing my brakes and actively flying the canopy. I control my heading during these tasks with my lower body using harness inputs to stay pointed in the desired direction.
Now once I clear my brakes I have preserved as much linear distance between myself and my pattern entry point as possible, and have remained directly on the wind line. In cases when the winds at opening altitude are stronger than the inherent forward speed of the canopy I am jumping, I have the advantage of the forward airspeed of the canopy reducing my (backward) ground speed as much as possible to keep me upwind until I choose to change position. At that point I have also prevented straying laterally off the wind line requiring some sort of olympic effort to crab back onto it and ensure I reach my pattern entry point.
At my experience level I like jumping in high winds under canopy because it requires my "A Game" and I get better by working through the challenges high winds present. Bear in mind that I trained into that over a lot of years and a lot of jumps. Anyone can do that with good coaching, choosing reasonable goals and choosing the right conditions for each stage in their progression.

In the conditions I am speaking of, facing into line of flight will allow me to hold my position over the ground or move backward (negative ground speed) as little as possible, but not travel back up line of flight.
Having inventoried the load already at the mockup and knowing who exited behind me, I keep those jumpers in sight - I look for each of them as soon as I open.
With proper exit separation due to the aircraft's reduced groundspeed (another subject altogether) I have plenty of space to set myself up for successful pattern entry.

At our DZ every student has to SPOT the plane at least three times and land with in 50 meters of the target before they get their solo. (Which means they try to figured what the ground winds are doing, winds at opening and half way). It is funny when we all go to a boogie and ask: "How does the guy at the door of the otter tells the pilot where to go in JR??"
Related to the post: It doesn't matter which direction you face on opening, and a good practice is, after opening always fly perpendicular away from the line of flight as long as none is there.
