UK RASP Ridge Day Tool: the hang gliders’ version

I’m interested in compiling a version of the ridge day tool for hang gliders (and a third for paragliders — can’t really leave you out :) ).

I personally think the ridge day tool is the best thing since sliced bread but I’m not sure it’s used that widely.

However I have a friend who hang glides and apparently this site is quite well known amongst them, so I’d like to extend the ridge tool to cover them too.

So if you have a favourite ridge and would like a tool that can scan seven days of forecasts and tell you when that ridge may be working, what I need from you is:

  • Site name
  • The lat/long in decimal form (e.g. “52.3675,-1.2433”), to four decimal places
  • The wind speed range (in knots) and the wind direction range the ridge works in (e.g. “300-350”)

I have a suspicion that the wind speeds will be fairly fixed — something like 8-15 knots for paragliders and 10-20 for hang gliders? Do educate me though!

Either leave a comment with the info below or use the “e-mail me” link on the left.

Gliding GP/Nympsfield

You heard it here last…

  • Nympsfield have moved to a proper blog (and WordPress at that, good choice boys). Link on left updated.
  • It’s the World Air Gliding Games GP (or something), supposedly at grandprixchile.org, though the site is not working for me at time of posting. I took the link from the FAI’s page too… Note that apparently this isn’t the Sailplane GP, as that page makes no mention of the Chile event. Whatever.
  • (I’ve also removed the Bicester link, as they’re not updating very often. At all.)

(No, as far as I know, Nympsfield haven’t been given a GP event!)

Not Saturday

But not forgotten, either.

(This point was due a friend pointing out that it wasn’t Saturday anymore, and hadn’t been for some time. I think it was actually a Wednesday at that point.)

What do you want from competition weather briefings?

Here’s your chance to say what you would like to see in competition weather briefings, and also what you want on those bits of paper everybody leaves on the floor afterwards.

First, the briefing itself.

You can chose up to five options, but try to chose fewer if you can—-briefings shouldn’t last forever! On the other hand, I need to cater for everyone—-not just those who have sat24.com on their smartphones.

I’ll be doing cross-sections for sure this year, but there’s more than one way of doing them. They can be for just the airfield, or one can make an attempt to “follow” the route, taking into account when and where the gaggles should be going, and what they’ll find there. My housemate found a wonderful old soaring weather book from the 1970s in our library with a section on competition forecasting, which had things like top-down charts of the task with weather symbols and cloud bases etc. pencilled in along the legs, which I rather liked. There were more ideas in there but I can’t remember them now! Will get the book out when I’m back…

RASP charts would be my favourite fields—-surface sun and cumulus base, plus probably climb strength. But show those charts for two times, and that’s six charts of detailed information to display. Can people really take all, or even any, of that in? How much would they remember if I asked them again in ten minutes?

Forecast charts would be blow-ups of maps of temperture or wind from sites such as Wetterzentrale—-again, same issues of data-overload.

Personally I’d like to see simpler briefings, with perhaps a synoptic, a sounding, latest sat pics, and then a chat around the cross-section. But tell me what you think.

[poll id=”5”]

What should be in the hand-outs? Obviously there’s a limit to what organisers can afford to print, so we’re probably limited to a double-sided sheet of A4 here, and the vote limit is 4 options. Bear in mind that if you want more than two items on the hand-out, they’re going to be A5-sized images.

[poll id=”6”]

Here’s a separate poll about what comp forecasters should be talking about—-what happened (and why) for yesterday? An outlook for the rest of the competition? Or just the day? You can vote for everything here if you want, but again, think about if you really want all of that.

[poll id=”7”]

Finally, there’s probably things that you’d like to see but I’ve not thought of and made an option, so let me know in the comments if there’s anything you’d like added as a poll option.

More live glider racing

It’s the World Air Games in Turin, with live tracking and re-runs. It’s the usual stuff with GPS trackers feeding flight-sim like graphics to show the race, and live commentary. Must say the quality of the video stream is disappointing—-generally quite blurry, and I can’t read the onscreen stats at all.

Looks like the next race kicks off at 12-1pm our time tomorrow, then there’s the final on Saturday.

Sarah Kelman is representing Britain (good luck Sarah!).

New polar satellite link

Update 9 June Old link is working again, so I’ve restored it. However the link that was standing in was rather lovely to look at, so I’m keeping it here. (The advantage of the “ftP” link is that you can get older images as well as the latest, and being zoomed in on the UK gets the most out of the images.)

It was pointed out to me that the existing polar satellite image link no longer worked (boo, it was a good site). I’ve replaced it with, as far as I know, a second-best. However the pass the link will display won’t always cover the UK :-( . I’ll have a look around for anything better…
