Hang gliding general :: Yosemite Hang Gliding Association 2016

The 2016 Yosemite hang-gliding season is almost upon us - opening weekend is June 3rd through 6th and the calendar is already full for that weekend.

If Yosemite is on your bucket list of places to fly in 2016, let us know a date when you would like to fly, and we'll do what we can to have a monitor available to safely get you off "The Rock".

We are currently working on a new website, and hopefully a sign-up system that is more user-friendly.

In the meantime, contact us if you'd like to get on the summer calendar - our flying season is June through September each year

You must be a H4 and have a monitor present with all flight activity.

email: speedglidinchris at gmail dot com

Fly safe!

Unless you're superman, the 0,7 horsepower å human is capable of generating cannot be described as towing, in fact, when you reach flying speed most of us are barely able to keep up with the glider.

Whenever I get a wing lifted during launch I lean/run towards the LIFTED wing! The oposite of what you are telling me to do but it works and I haven't crashed in a long time. My experience trumps your theory.


What else is it if it’s not towing? If the word bothers you I’ll use something else. Splunging is as good a word as any.

This has nothing to do with horsepower. In a breeze a man just has to hold onto a rope, not too much horsepower involved there.

It has to do with the fact the glider cannot do what it wants to do because of a 200lb tether namely the pilot.
If the glider banks but can’t go where it naturally wants to go because of a tether then we are talking towing dynamics. If the pilot’s feet have left the ground or are hardly touching then we are not.

I’m not telling you to do anything and I assume your crash free take offs don’t involve you running down a hill hands off. As a responsible pilot you will be holding the control frame and supplying input.

Sadly I can’t say I have not crashed in a long time but that was a landing so it doesn’t count.

I would second all of the above as to flying behavior. Never bought a new wing before but I just ordered one of these.

Hang gliding general :: RE: So Cal the last week of April

I'm not not much of a weather guru around here but I'd say this:
Saturday I think we'll be shut down at Kagel but Sunday has potential to be very good if we can get off the hill and I bet we will. The rest of the week should probably be flyable both places, but the picture is a little unsettled. The last half of April is when we usually get our highest days of the year, but we may have already seen them this past week with one guy on Monday flying Kagel to Crestline and another almost.

I guess that doesn't help much but hey, life is uncertain. If you want a sure thing, wait a few weeks and you'd be pretty much guaranteed flights every day but with lower odds of hitting an exceptionally good day.

First night of the flight, the profile tells the story. Topped out at 30K with 100% batteries, bottomed out at 3900 with less than 25% battery before the sun came out and he started climbing. Looks like was a glider until around 8K and then used the batteries to flatten out.

I bet the pucker factor that close to the ocean was on the high side. Wow.

One of my favorite quotes from his book that always stuck with me,

"I'd rather hit the ground at 70 miles trying to go 250 miles than watch the sun set and run out of lift at 190 miles"

You can decide if this attitude made him one of the greatest pilots, an inspiration to many trying to improve their XC skills, or a total asshole - or maybe all three...

Aside from Torrey, pretty much all the sites you listed are fairly unregulated. There is not yet a USHPA toll booth that you are required to swipe your membership card to gain access to the site, although I think this is coming in the near future.

Wouldn't the glider's response to the vector change actually be a roll in the opposite direction?

Combination of altitude management and battery power at lower altitudes.
Climb and recharge batterys during the day then glide at nite until low and use battery power until the sun again starts the cycle.
Pretty amazing that they are making it work so well.

Makes me wonder when the first solar Hang Glider crossing of the US will be!!!.
E-assist take off -Thermal and glide - Land and deploy solar panel - Charge and repeat.

I rejoined USHPA this year after a 15 year layoff. H-0... After busting my butt for 4 months getting into shape and losing weight, I went down to Lookout (where I trained in 1996) for a week. By some miracle of fate, my 62 year old legs held out on the torturous flat slope launch (where they insist on no wind launching...just to make it more technique sensitive:) , and I regained my H-2 and a mountain launch. Didn't have time to solo for my AT, but to get the ratings starting anew as a complete noob is a great accomplishment, when you consider that the body as well as the weather all have to cooperate in a limited time frame. All in all, I did about 30 foot launches in three sessions to get the job done. Thank God they now have Kubota 4 wheelers shuttling to the top of the training hills, or I would have coded out. Back to flying in the local club. Felt they prepared me well. Great one on one attention, especially when it's time for the run from the radial ramp. Good folks.

Yup, batteries. However, they do use them as sparingly as possible so the overnight flying is all a gentle descent and the daytime is for climbing. The reason they've been stuck here since July is that they didn't have sufficient cooling for the batteries on the long run from Japan and pretty much cooked 'em.

Quotes from their web site...
Quote: Solar Impulse 2 will have to do what no airplane has ever done before: fly through 5 consecutive days and nights without using any fuel
Which made me think that it must be generating enough power during daylight to not only sustain flight, but also to charge batteries, but then I found this...
Quote: Si2 is currently at 22763ft and still climbing to reach a high altitude before night sets in #futureisclean
So maybe not batteries. Maybe it just flies as a glider at night and stores energy during the day in the form of altitude. That would make more sense as batteries would add weight. Is that even possible though? Gliding through an 8 to 12 hour night would require a lot of altitude to start with and a very low sink rate. 50 fpm = 30k ft over 10 hrs.
