Dear friends,
We have been extremely excited about the Qualifying Grand Prix in Chile from
January 17th to 25
I wonder if they will offer the same stretched cockpit as the new Duo
Discus XL?
Pretty good news that they'd receive so many orders so quickly despite
the global economic crisis.

Are you casting aspersions as to the performance of the HP-14 or

It's mandated for larger ships and SOLAS use, but is also gaining

As to why the numbers work out like that, it's probably something an
actuary could answer better but I expect it's because most payouts will
be around or under the $1million mark, so even if you have $3million
cover, most times a claim is made the payout will be less.
I guess this means that it's

A new device, that is NOT a replacement to a PLB, has become available
on the market: the SPOT Satellite Messenger.
It uses the globalstar sat network, contains a GPS, and allows tracking

type messages.

Not necessarily, Mark. For convection we need temperature differences
between the airmass and ground heating. So global warming could
actually make for worse gliding conditions.

Hi Don,
Your Ipaq 5900 will work fine as a glide computer.
XCSoar (www.xcsoar.org) is a free glide computer and moving map system

With your figures, approximately 17 hours were flown on average per
pilot. Assuming half the launches were cross-country at 100kph average,
this gives 17*100/2 = 850 km xc flown per pilot.

Hi Todd,
Reichmann's technique as described in his book does indeed work. I
think you may be misunderstanding it slightly because of what might be a
translation error or oversimplified use of language.
To be more formal (and correct), his technique is:
- 1) While the climb is improving, flatten
developers,
users and testers working on it on a daily basis.

Hi Tom,
I don't think the image of gliding in Australia is by any means perfect,
but I just wanted to emphasise that the problem is not that there are
too many 'youth-challenged' pilots --- indeed I think it is a positive
thing that they are able to dominate the sport here if there isn't

Perhaps this can be turned into a positive view:
How many sports offer deep challenges to provide a lifetime of
entertainment and honing of skills; that allow talented and intuitive
young competitors to win yet do not exclude those out of their physical
prime?
I see this as one of the most wonder
I know a few pilots that were there; apparently it was a VNE overspeed

other will tend to have a similar GPS altitude offset, this is not
guaranteed to be true, due to the fact that each receiver may in fact

Yes, all FLARMs worldwide have a time-bomb that requires the firmware to

Hi all,
A gliding safari from Benalla to the Flinders Ranges is planned starting
boxing day to about 5 January. We have about 8 gliders going and would
like to invite another two gliders to come along on the adventure.
Anyone interested?

Another particularly annoying thing about the newer phone services
is that they are increasingly more difficult to work with at a low level
from the phone.
GSM stands out at having a somewhat open standard interface for sending
and receiving SMS messages; CDMA etc have phone-manufacturer proprieta
areas.
I did my testing with GSM mobile phones.
Anyhoo, it's doable.

There are a few things that can be done to make the most of the PDA
