Good suggestion, Mattew. Simple and logical. But the rule would have to be
written so as to prevent someone simply pressing their event button every
four minutes...

Bad luck. Haven't any other ideas. Maybe junk the Altair and run it on a
tablet? Though I don't know if you can achieve the larger text. All the

Re: [Aus-soaring] Parachute

[Paul Mander]

Just to add to Mike's very appropriate comments, the mantra once was that
on hearing a bang, dirty up the glider. Drop the U/C, open the spoilers, as
a reflex action before all others. That way the speed doesn't run away so
quickly and it will remain possible to open the canopy.

Hi Scott, I've booked at the Shamrock and I'll enter in a moment.
At last year's comps the NSWGA provided oxygen top ups for free. The
equipment is in Narromine, I believe.
It was very well received and a great benefit.
Will we have the same facility this year?
All the best, Paul.

Aye to that. Nigel was very generous with his time when we were all

practical support of the introduction of these devices; they were not
universally welcomed at the time.

Mike, that looks like a good app, I've just installed it on my Nexus 5x and
it is very responsive and smooth.
The older versions of these non-mechanical gyros were only good for a few
minutes, after which time they would wander or topple; would you describe
this later model as being stable enough for 15 minutes or so?
If so, priceless as a means to get out of a bad spot.

[Aus-soaring] SkySight and Wave

[Paul Mander]

Take a look at the wave display for today on Matthew Scutter's new
forecasting package, SkySight.
It shows the possibility of a flight in wave from Bunyan to Bairnsdale to
Kempsey; 1020 km, if one could address the airspace issues.
That possibility is exciting, but it also demonstrates the usefulness of
the SkySight model. I recommend it.

Re: [Aus-soaring] SkySight.io - next generation soaring weather forecast

[Paul Mander]

Hello Matthew, and congratulations on your initiative.
I'd like to sign up, but when I entered your website it asked for my credit
card details and that caused me to retreat..
How secure is your site?
All the best, Paul Mander
