Opps! I must amend one of the task TPs. Substitute Jerilderie A/F for
Deniliquin A/F. I could say "just testing" (Deniliquin gives 904 km - I wish),
but I would be lying. Sorry about that!
Incidentally, before GPS, and I can't pin the date when I got my first machine,
we had to measure distances off a map: A paper map that might shrink or expand,
depending on the atmospheric conditions! The formula existed to calculate great
circle distances, but you needed to be a mathematical genius to use this, and
have access to 7 figure tables to boot. Yeah, and the formula also changed from
time to time too, depending on the model of the Earth that was being used at
the time. Of course it wasn't called Earth - it was "a flattened oblate
spheroid"... And in remote areas (no obvious landmarks), we had to fly on
compass headings, and calculate drift etc. All I can say is thank God that this
aspect of the "good old days" (just like the start gate), is gone forever.
The introduction of GPS into gliding was without doubt one of the movements
great boons.

Hi All,
If you like a good story, here is Col's account of his 750 km flight
(referred to by Bruce), as it appears on the Canberra Gliding Club's web site.
Date is 7 Jan 1999.
The 4th Jan 1999 was OK too. In Libelle BL did 764 k with a total flight time
of 7h 59m: Benalla - Becom - Deniliquin A/F - The Rock - Urana - Benalla.

This really was a special run of weather. There were several great days in
a row, but the last was the best as far as Temora went - and it was the only
day I didn't have to work. There were at least four 750km flights in club class
gliders on that day - Ziggy Kominek in Jantar Std 2 CQT, Col Vassarotti in Std
Libelle BE, Gary Stevenson in Std Libelle BL, and myself in Std Cirrus AM. I
think David Pietsch may have done a 750 also in ASW20 ZZ (not sure it was known
as ZZ then) although at the time the 20 was a bit above club class.
This was the same day that Tom Claffey set the Std Class Australian record
for a 1000 (1016km) FAI triangle speed in Discus B FV. Gary and I did
Temora-Hillston-Narromne-Temora - a 750km FAI triangle (756km). Mine was
memorable for several reasons - a 12:25 launch after rigging with an optimistic
750 in the little black box, then cruising at 100 knots in a Cirrus to stay out
of the streeting cloud at 11,000 ft on the first leg to Hillston, passing Tomas
Suchanek and Tom at Forbes on the last leg (they were en route to Narromine),
landing after 7:02 (107km/hr)......it was an awesome flight. 900 was possible
in the Cirrus that day. Gary may recollect it too.
I think that that may have been they weather cycle that got Harry from
Keepit to Gawler, but not sure.
The spoiler was the tug release point for me was on the wrong side of the
airfield (en route) so I was never able to claim it. Oh well - I'll claim the
750 when I do my 1000 I thought. Never got there despite many attempts over 10
years (in Discus A D1 - best 925km but not claimable either due abandoning 2nd
turn) - just needed that magic '99 day again. I watched weather closely whilst
juggling work commitments (which as a water resources engineer also allowed me
to get paid for weather watching!), but never saw a day lke it, so I don't
subscribe to the 7 year cycle!
Cheers

Hi All,
The amazing flights referred resulted from some rather special weather
conditions.Most of you would remember the Sydney to Hobart fleet which ran into
a ferocious storm of the Victorian coast and into Bass Strait. Some boats were
sunk and lives lost. This abnormal low pressure system dumped billions of
cubic metres of cold dry air over Victoria and much of NSW, much further north
than the usual cold fronts which pass through at that time of the year and
produce the usual good conditions which are centred along the line Waikerie,
Tocumwal and Corowa . As the succeeding high pressure system went through this
low dew point air warmed up day by day and produced the ideal temperature
profile, including cloud bases of up to 14,000 ft. I remember it well. The
rather wetter patterns of the last couple of years have been the result of the
high pressure systems dragging in warm moist ocean air. the length of fetch has
often extended over a 1,000 km resulting in dew points of up to and over 20
deg. The dew point of air from the southern ocean is usually below 10 an
sometimes a minus number

Perhaps Adam is referring to the El Nino / La Nina oscillation, which
has a large influence on Queensland's weather patterns.
Very roughly 5 year cycles.

WPP,
"I think the weather cycle goes in 7 yr increments." Now that is a very
brave statement indeed!
Memory is a fallible thing, but I seem to recall (from many -30/40?
-years
ago), that the Dutch had to hand at that time, over 400 years worth of
continuous weather records. This data (exactly what was available was
not
stated), was analysed for cyclic pattens. The result - NO PATTEN AT ALL
COULD BE DEDUCED.
Does anyone know about this or similar work, and can comment further?

G'day All,
I've been keen to set up some unofficial club class records since
getting
my Cirrus. Hope you see the concept/idea as I've seen it. The reason
behind
it,
As per '3.2' - All in good fun, to give those who can't go for
official
records due to financial reasons (eg, not being able to obtain a
Discus 2,
to go for a STD class record) or not being their preferred class.
In 1999, Tom Claffey & others experienced some amazing weather
conditions
in AUS. I think that the weather cycle goes in 7yr increments. Now
approaching 14yrs later, I think we could be in for a good season -
cross
your fingers, I & many others would love a regular great season for a
change!!!
All comments & potential additions on the below welcome.
SeeYou,
WPP

Unofficial Australian Club Club Class Records - Rules V1.0
Concept by Adam Woolley
Written by Adam Woolley
1 - Philosophy: To provide a friendly and honest unofficial record
list/rules for Australian pilots, whom race/fly in Australian
airspace, in
the gliders on the Australian Club Class Handicap list provided on
the GFA
website.
2 - RULES: Use the Australian Junior Record Rules (found on
www.joeyglide.com.au & www.ajgc.org.au websites) if you want to go
'official
official', as kindly put together by Andrew Maddocks. The below are
amendments & simple reminders, in no particular order & are generally
based
on the KISS principle, with safety in mind!
If you don't want to read the rules, & if your an honest person - the
below will suffice.
2.1 - Entries Open: 18 JUL 2012.
2.2 - Eligable Gliders: Club Class Gliders, as found on the current
years
GFA Club Class Handicap list.
2.3 - Handicaps: the use of the current GFA Club Class Handicap list
will
be used for the flight (date) submitted.
2.4 - Reference Weight: the use of the current reference weight as
provided by the GFA club class handicap list for the (date) submitted.
2.5 - After Market Modifications: No penalty will be given for the
addition of winglets, wing fillets or extractor vents.
2.6 - Handicap Adjustments: 0.005 disadvantage per part there of 12kg
over
REFERENCE WEIGHT. No performance advantage given for gliders that fly
below
REFERENCE WEIGHT.
2.7 - Start Rule: 1km radius over pre-declared waypoint.
2.8 - Turnpoint(s): 500m radius.
2.9 - Finish: 3km radius from the pre-declared waypoint.
2.10 - Record submission: E-Mail your details appropriate for the
flight
(Start & Finish Point, Turnpoints (if not a free distance or height
gain)
inc waypoint details, glider type, approximate weight (or accurate if
known)), & *.igc file to, agwool...@hotmail.com within 48hrs of 'end
of
roll'.
2.11 - Start/Finish Heights: You must finish at the predetermined
finish
point, within a 1000m of your start height & predetermined start
point. For
'free distance' one way flights, you must start (predetermined point)
below
1000m AGL & land safely at any point.
2.12 - Records: Each record will stay firm until beaten by the current
years GFA handicap for the club class glider used. ie, won't be
changed
each season if the glider handicap or reference weights change.
2.13 - Declarations: A flight must be declared before going through
the
start circle, unless it's a Free Distance flight.
3 - GENERAL
3.1 - Remember, unofficial. If you cheat intentially or not being
honest,
you're only ripping your fellow mates off.
3.2 - All in good fun, to give those who can't go for official
records due
to financial reasons (eg, not being able to obtain a Discus 2, to go
for a
STD class record) or not being their preferred class.
3.3 - If the GFA thinks its a good idea, more than happy for the
rules to
be re-written officially. Though I would like to think that they'll
accept
the unofficial records, even of they have an unofficial column until
the
record is beaten officially - to reward the efforts that we've
previously
gone too!
3.4 - I know there's lots of holes in the above. Use your noggin for
what
you think is right and fair!
3.5 - It's just a game, have fun!
4 - Records obtainable
4.1 - An excel spreadsheet available on request, until I find a place
to
upload it to the web.
4.2 - Free Distance
Free Distance
Free Out & Retun Distance
Free Three Turnpoint Distance
4.3 - Distance to Goal
Straight Distance to Goal
Three Turnpoint Distance
Out & Return Distance
